REMARKS:
082100Z POSITION NEAR 22.5S 174.3W.
08APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 408
NM SOUTHEAST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 27
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY (EIR) PORTRAYS AN ELONGATED SYSTEM WITH WARMING CLOUD TOPS
AND A PINHOLE EYE THAT BECAME RAGGED, THEN WAS SUBSUMED INTO THE
CENTRAL DEEP CONVECTION. THERE IS HIGH CONFIDENCE IN THE INITIAL
POSITION, PLACED BY EXTRAPOLATING A PINHOLE EYE THAT THEN
DISAPPEARED. THERE IS FAIR CONFIDENCE IN THE 110 KT INITIAL INTENSITY
BASED BETWEEN DVORAK FINAL AND CURRENT INTENSITY (CI) ESTIMATES OF
T5.5 (102 KTS) TO T6.5 (127 KTS) AND AN ADVANCED DVORAK TECHNIQUE CI
OF T6.4 (124 KTS) WHILE THE RAW T-NUMBER IS T4.8 (UNDER 90 KTS).
OBSERVATIONS FROM TONGA, 53 NM TO THE NORTHESAT, REPORTED WINDS OF
50G75 KTS AND 989 MB AT 081830Z AS THE FAST-MOVING SYSTEM PASSED TO
ITS SOUTH. THE CURRENT INTENSITIES ARE LIMITED BY SPIN-DOWN TIME FOR
THE TANGENTIAL WIND SPEEDS TO REFLECT THE CHANGES IN SECONDARY
CIRCULATION THAT DROVE THE WANING CONVECTION. HIGH (20-40 KT)
VERTICAL WIND SHEAR (VWS) AND CONVERGENT NORTHWESTERLY FLOW ALOFT ARE
OFFSETTING ROBUST POLEWARD OUTFLOW AND WARM (27 DEGREES CELSIUS) SEA
SURFACE TEMPERATURES, RESULTING IN AN UNFAVORABLE ENVIRONMENT FOR
FURTHER INTENSIFICATION AND THE INCREASING DISORGANIZATION. FOR THE
DURATION OF THE FORECAST, TC 25P WILL ACCELERATE ALONG A SIMILAR
TRACK AS IT FOLLOWS THE SOUTHWESTERN PERIPHERY OF A NORTHWEST-
SOUTHEAST ORIENTED SUBTROPICAL RIDGE (STR). THE ENVIRONMENT WILL
BECOME INCREASINGLY HOSTILE DUE TO STRONG VWS AND SSTS BELOW 26
DEGREES CELSIUS AS IT TRACKS EAST-SOUTHEASTWARD. BY TAU 12, TC 25P
SHOULD BEGIN INTERACTING WITH THE MIDLATITUDE WESTERLIES AND START
EXTRATROPICAL TRANSITION (ETT). ETT SHOULD COMPLETE BY TAU 36 WITH
THE CYCLONE BECOMING A STORM FORCE, COLD CORE LOW. NUMERICAL MODEL
GUIDANCE IS IN EXCELLENT AGREEMENT, LENDING HIGH CONFIDENCE TO THE
JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081800Z IS 41
FEET. NEXT WARNINGS AT 090300Z, 090900Z, 091500Z AND 092100Z.

REMARKS:
081500Z POSITION NEAR 21.1S 176.9W.
08APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
248 NM SOUTHEAST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 23
KNOTS (KTS) OVER THE PAST SIX HOURS. THERE IS HIGH CONFIDENCE IN THE
INITIAL POSITION, PLACED NEAR THE CENTER OF A 20 NM OBLONG EYE.
THERE IS FAIR CONFIDENCE IN THE 115 KT INITIAL INTENSITY BASED ON
PGTW/PHFO DVORAK INTENSITY ESTIMATES FROM T6.0-6.5 (115-127 KTS).
MODERATE (15-20 KT) VERTICAL WIND SHEAR (VWS) IS PARTIALLY
OFFSETTING ROBUST POLEWARD OUTFLOW AND WARM (27-28 CELSIUS) SEA
SURFACE TEMPERATURE TO MAKE THE ENVIRONMENT LESS SUPPORTIVE THAN SIX
HOURS AGO. FOR THE DURATION OF THE FORECAST, TC 25P WILL ACCELERATE
ALONG A SIMILAR TRACK AS IT FOLLOWS THE SOUTHWESTERN PERIPHERY OF A
NORTHWEST-SOUTHEAST ORIENTED SUBTROPICAL RIDGE (STR). THE
ENVIRONMENT WILL BECOME INCREASINGLY HOSTILE DUE TO STRONG VWS AND
COOL SST AS IT TRACKS EAST-SOUTHEASTWARD. BY TAU 12, TC 25P SHOULD
BEGIN INTERACTING WITH THE MIDLATITUDE WESTERLIES AND START
EXTRATROPICAL TRANSITION (ETT). ETT SHOULD COMPLETE BY TAU 36 WITH
THE CYCLONE BECOMING A GALE FORCE, COLD CORE LOW. NUMERICAL MODEL
GUIDANCE IS IN EXCELLENT AGREEMENT, LENDING HIGH CONFIDENCE TO THE
JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081200Z IS
45 FEET. NEXT WARNINGS AT 082100Z, 090300Z, 090900Z AND 091500Z.//

REMARKS:
080300Z POSITION NEAR 19.4S 178.7E.
08APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 62
NM SOUTHWEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 19
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THAT ONCE AGAIN, TC 25P HAS PROVEN ESPECIALLY
RESILIENT WITH A SMALL, CLOUD FILLED, PINHOLE EYE DEVELOPING WITHIN
THE PAST FEW HOURS INDICATIVE OF ANOTHER ROUND OF INTENSIFICATION.
THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON BOTH A
RADAR FIX FROM PGTW BASED ON THE FIJI COMPOSITE RADAR LOOP, AND A
PARTIAL 080006Z GMI 36 GHZ MICROWAVE IMAGE WITH A WELL DEFINED CYAN
RING, AT LEAST ON THE EASTERN HALF OF THE EYE CAPTURED BY THE
MICROWAVE PASS. THE INITIAL INTENSITY IS A SLIGHT HEDGE UPWARD FROM
THE SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES OF T6.0 (115
KNOTS) FROM PGTW AND PHFO, AN ADVANCED DVORAK TECHNIQUE ESTIMATE OF
T6.1 (118 KNOTS), AND A SATELLITE CONSENSUS ESTIMATE OF 112 KNOTS.
THE HEDGE UPWARD TO 120 KNOTS IS BASED MOSTLY ON THE APPEARANCE OF A
CYAN RING AND STRUCTURE IN THE MICROWAVE IMAGERY. THE OVERALL
ENVIRONMENT REMAINS FAVORABLE THOUGH SIGNS ARE STARTING TO EMERGE
THAT THIS MAY BE CHANGING. VWS IS LOW TO MODERATE (10-15 KNOTS),
SSTS REMAIN WARM (27-28 DEG CELSIUS) AND OUTFLOW IS STRONG
ESPECIALLY TOWARDS THE EAST AND SOUTHEAST. THE UPPER-LEVEL POINT
SOURCE THAT HAS BEEN ENTRENCHED OVER TC 25P THROUGH THE PAST FEW
DAYS IS STARTING TO WEAKEN AND BE REPLACED BY MORE STRAIGHT WESTERLY
FLOW ALOFT, WITH WATER VAPOR IMAGERY SHOWING THE PRESSURE PRODUCED
BY THIS FLOW ON THE WESTERN SIDE OF THE SYSTEM. COMBINED WITH A
RAPID MOVEMENT SOUTHEAST TOWARDS COOLER WATERS, AND STEADILY
INCREASING VWS, TC 25P IS FORECAST TO SLOWLY WEAKEN THROUGH TAU 12,
THEN RAPIDLY WEAKEN THEREAFTER THROUGH THE REMAINDER OF THE FORECAST
PERIOD. THE SYSTEM IS FORECAST TO TRACK SOUTHEASTWARD THROUGH TAU 48
ALONG THE PERIPHERY OF A NORTHWEST-SOUTHWEST ORIENTED STR CENTERED
FAR TO THE NORTHEAST. BY TAU 36, TC 25P WILL BEGIN INTERACTING WITH
THE MID-LATITUDE WESTERLIES AND BY TAU 48 WILL BECOME ABSORBED INTO
THE STRONG WESTERLIES AND COMPLETE TRANSITION AS A STORM STRENGTH
EXTRATROPICAL CYCLONE. DYNAMIC MODEL GUIDANCE IS IN EXCELLENT
AGREEMENT THROUGH TAU 24, WITH INCREASING SPREAD THEREAFTER, THOUGH
SPREAD IS ONLY 155 NM AT TAU 48. THE JTWC FORECAST IS PLACED ALONG
THE SOUTHERN EDGE OF THE TIGHTEST GROUPING OF MODEL TRACKERS WITH
HIGH CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z IS 45
FEET. NEXT WARNINGS AT 080900Z, 081500Z, 082100Z AND 090300Z.//

MERGE THAT THIS MAY BE CHANGING. VWS IS LOW TO MODERATE (10-15 KNOTS), SSTS REMAIN WARM (27-28 DEG
CELSIUS) AND OUTLOW IS STRONG ESPECIALLY TOWARDS THE EAST AND SOUTHEAST. THE UPPER-LEVEL POINT SO
URCE THAT HAS BEEN ENTRENCHED OVER TC 25P THROUGH THE PAST FEW DAYS IS STARTING TO WEAKEN AND BE R
EPLACED BY MORE STRAIGHT WESTERLY FLOW ALOFT, WITH WATER VAPOR IMAGERY SHOWING THE PRESSURE PRODUC
ED BY THIS FLOW ON THE WESTERN SIDE OF THE SYSTEM. COMBINED WITH A RAPID MOVEMENT SOUTHEAST TOWARD
S COOLER WATERS, AND STEADILY INCREASING VWS, TC 25P IS FORECAST TO SLOWLY WEAKEN THROUGH TAU 12,
THEN RAPIDLY WEAKEN THEREAFTER THROUGH THE REMAINDER OF THE FORECAST PERIOD. THE SYSTEM IS FORECAS
T TO TRACK SOUTHEASTWARD THROUGH TAU 48 ALONG THE PERIPHERY OF A NORTHWEST-SOUTHWEST ORIENTED STR
CENTERED FAR TO THE NORTHEAST. BY TAU 36, TC 25P WILL BEGIN INTERACTING WITH THE MID-LATITUDE WEST
ERLIES AND BY TAU 48 WILL BECOME ABSORBED INTO THE STRONG WESTERLIES AND COMPLETE TRANSITION AS A
STORM STRENGTH EXTRATROPICAL CYCLONE. DYNAMIC MODEL GUIDANCE IS IN EXCELLENT AGREEMENT THROUGH TAU
24, WITH INCREASING SPREAD THEREAFTER, THOUGH SPREAD IS ONLY 155 NM AT TAU 48. THE JTWC FORECAST
IS PLACED ALONG THE SOUTHERN EDGE OF THE TIGHTEST GROUPING OF MODEL TRACKERS WITH HIGH CONFIDENCE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z IS 45 FEET. NEXT WARNINGS AT 080900Z, 081500Z, 082100Z

REMARKS:
072100Z POSITION NEAR 18.7S 176.8E.
07APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 149
NM WEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 17 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS DEEP CONVECTION WRAPPI
NG TIGHTLY ABOUT A CLOUD-COVERED AND OBSCURED LLCC. THE INITIAL POSITION IS PLACED WITH HIGH CONFI
DENCE BASED ON A 1800Z RADAR ANALYSIS FIX FROM PGTW, BASED ON A WELL-DEFINED RADAR EYE IN THE NADI
, FIJI RADAR LOOP, SUPPORTED BY A 20 NM EYE IN AT 071654Z SSMIS 89 GHZ MICROWAVE IMAGE, WHICH ALSO
SHOWS THAT THE EYEWALL IS WELL DEFINED AND COMPLETELY SURROUNDS THE CENTER. THE LOWER LEVELS ARE
NOT AS WELL DEFINED AS INDICATED BY TEH 37 GHZ BAND, BUT THE MICROWAVE EYE IS STILL EVIDENT. THE I
NITIAL INTENSITY OF 110 KNOTS IS ASSESSED WITH HIGH CONFIDENCE, AND IS HEDGED SLIGHTLY HIGHER THAN
THE AGENCY CURRENT INTENSITY ESTIMATES OF T5.5 FROM PGTW AND PHFO IN LIGHT OF AN ADVANCED DVORAK
TECHNIQUE RAW T# OF 6.4 (CI OF 5.4) AND A 071329Z AMSR2 WINDSPEED RETRIEVAL OF 119 KNOTS. THE ENVI
RONMENTAL REMAINS FAVORABLE WITH LOW (5-10 KNOTS) VWS, STRONG DIVERGENT POLEWARD AND EASTWARD OUTF
LOW AND WARM (27-28 DEG CELSIUS) SSTS. THROUGH THE FORECAST PERIOD TC 25P WILL TRACK ALONG THE SOU
THWEST PERIPHERY OF AN ELONGATED STR TO THE NORTHEAST, WHILE STEADILY ACCELERATING ALONG THE TIGHT
GRADIENT BETWEEN THE STR AND AN APPROACHING MID-LATITUDE TROUGH. OVER THE NEXT 24 HOURS, TC 25P W
ILL WEAKEN STEADILY BUT SLOWLY AS VWS SLOWLY INCREASES AND SSTS CONTINUE TO SLOWLY COOL. HOWEVER,
OUTFLOW WILL REMAIN ROBUST, AND WILL TEND TO SLOW THE RATE OF WEAKENING. BEYOND TAU 24 HOWEVER, TH
E SYSTEM WILL BEGING TO INTERACT MORE WITH THE MID-LATITUDE WESTERLIES AND VWS WILL INCREASE MORE
RAPIDLY WHILE SSTS DECREASE, LEADING TO MORE RAPID WEAKENING BEYOND TAU 36. BY TAU 36, THE SYSTEM
WILL START EXTRATROPICAL TRANSITION AND IS EXPECTED TO COMPLETE THIS TRANSITION TO A COLD CORE EXT
RATROPICAL SYSTEM BETWEEN TAU 48 AND TAU 72, IF NOT EARLIER. DYNAMIC MODEL GUIDANCE IS IN STRONG A
GREEMENT THROUGH TAU 36, WITH INCREASING UNCERTAINTY BOTH ALONG TRACK AND CROSS TRACK AFTER TAU 48
. THE JTWC OFFICIAL FORECAST LIES ON THE SOUTHERN EDGE OF THE TIGHEST GROUPING OF MODEL GUIDANCE,
TRENDING MORE TOWARDS THE ECMWF SOLUTION. THERE IS OVERALL FAIR CONFIDENCE IN THE JTWC FORECAST TR
ACK, PRIMARILY DUE TO THE INCREASED UNCERTAINTY BEYOND TAU 48. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
071800Z IS 42 FEET. NEXT WARNINGS AT 080300Z, 080900Z, 081500Z AND 082100Z.//

REMARKS:
071500Z POSITION NEAR 17.7S 174.9E.
07APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
255 NM WEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 14
KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS DEEP CONVECTION SURROUNDING AND OBSCURING
THE LOW LEVEL CIRCULATION CENTER, POSSIBLY INDICATING AN EYE MAY BE
TRYING TO FORM. THE INITIAL POSITION IS PLACED IN THE CENTER OF THAT
DEEP CONVECTION WITH GOOD CONFIDENCE. THE 110 KT INITIAL INTENSITY
FALLS NEAR THE AVERAGE OF PGTW/PHFO DVORAK CURRENT INTENSITY
ESTIMATES OF T5.5-6.5 (102-127 KTS) WITH LOW CONFIDENCE. WITH LOW
(10-15 KT) VERTICAL WIND SHEAR (VWS), ROBUST POLEWARD OUTFLOW, AND
WARM (28-29 CELSIUS) SEA SURFACE TEMPERATURE (SST), THE ENVIRONMENT
IS SUPPORTIVE. FOR THE DURATION OF THE FORECAST, TC 25P WILL TRACK
ALONG THE SOUTHWESTERN PERIPHERY OF A NORTHWEST-TO-SOUTHEAST
ORIENTED SUBTROPICAL RIDGE (STR). THROUGHOUT THE FORECAST PERIOD,
THE ALONG TRACK SPEED WILL ACCELERATE AS THE SYSTEM MOVES INTO THE
MIDLATITUDE WESTERLIES. THROUGH TAU 24, THE INTENSITY SHOULD REMAIN
AROUND 105-110 KTS, ALTHOUGH THE TC MAY GET STRONGER IF AN EYE WERE
TO FORM. AROUND TAU 36, HIGH VWS WILL BEGIN WEAKENING THE INTENSITY.
AT THAT TIME, INTERACTION WITH COOL SST AND THE MIDLATITUDE
BAROCLINIC ZONE SHOULD BEGIN EXTRATROPICAL TRANSITION. BETWEEN TAU
48 AND TAU 72, TC 25P WILL HAVE TRANSFORMED INTO A COLD CORE
EXTRATROPICAL CYCLONE. NUMERICAL MODEL GUIDANCE IS IN EXCELLENT
AGREEMENT THROUGH TAU 24. AFTERWARD, SPREAD INCREASES PRIMARILY DUE

KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS DEEP CONVECTION SURROUNDING AND OBSCURING
THE LOW LEVEL CIRCULATION CENTER, POSSIBLY INDICATING AN EYE MAY BE

FALLS NEAR THE AVERAGE OF PGTW/PHFO DVORAK CURRENT INTENSITY
ESTIMATES OF T5.5-6.5 (102-127 KTS) WITH LOW CONFIDENCE. WITH LOW
(10-15 KT) VERTICAL WIND SHEAR (VWS), ROBUST POLEWARD OUTFLOW, AND
WARM (28-29 CELSIUS) SEA SURFACE TEMPERATURE (SST), THE ENVIRONMENT
IS SUPPORTIVE. FOR THE DURATION OF THE FORECAST, TC 25P WILL TRACK
ALONG THE SOUTHWESTERN PERIPHERY OF A NORTHWEST-TO-SOUTHEAST

REMARKS:
070300Z POSITION NEAR 16.9S 172.0E.
07APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 421
NM WEST OF SUVA, FIJI, HAS TRACKED EASTWARD AT 15 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED AND VISIBLE SATELLITE IMAGERY SHOWS THAT TC 25P HAS REI
NTENSIFIED, OR AT LEAST ARRESTED THE WEAKENING TREND FOR A SHORT TIME, WITH THE REAPPEARANCE OF A
PINHOLE EYE OVER THE PAST FEW HOURS. THE SYSTEM HAS MOISTENED SINCE THE PREVIOUS WARNING, PARTICUL
ARLY ON THE EASTERN SIDE, WHICH HAS ALLOWED FOR REGENERATION OF CONVECTION AROUND THE CORE OF THE
SYSTEM. A 0056Z GMI 37 GHZ MICROWAVE SHOWED THE REDEVELOPMENT OF AN EYEWALL SURROUNDING THE SMALL
EYE, WITH THE EXCEPTION OF THE EASTERN SIDE WHICH IS STILL SOMEWHAT DISORGANIZED AND RAGGED. THE I
NITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE PINHOLE EYE IN THE VISIBLE IMAGERY, SU
PPORTED BY THE MICROWAVE EYE FEATURE IN THE PREVIOUSLY NOTED GMI MICROWAVE IMAGERY. THE INITIAL IN
TENSITY OF 115 KNOTS IS ASSESSED WITH HIGH CONFIDENCE BASED ON DVORAK CURRENT INTENSITY ESTIMATES
OF T6.0 (115 KNOTS) FROM PGTW AND PHFO, AN ADVANCED DVORAK TECHNIQUE ESTIMATE OF T6.1 (117 KNOTS)
AND A SATELLITE CONSENSUS ESTIMATE OF 114 KNOTS. ENVIRONMENTAL ANALYSIS SHOWS THAT THE SYSTEM REMA
INS IN A FAVORABLE ENVIRONMENT, WITH LOW (5-10 KNOTS) VWS, WARM (28-29 DEG CELSIUS) SSTS, AND STRO

UTHWESTERN PERIPHERY OF A DEEP-LAYER STR LOCATED FAR TO THE NORTHEAST, AND WILL CONTINUE TO TRACK
SOUTHEAST WHILE ACCELERATING THROUGH THE FORECAST PERIOD. THE OVERALL ENVIRONMENT IS FORECAST TO R
EMAIN FAVORABLE FOR THE NEXT 24 HOURS, THOUGH THE UPPER-LEVEL POINT SOURCE CURRENTLY OVER THE SYST
EM WILL BEGIN TO MOVE AWAY SLOWLY, LEADING TO INCREASING SHEAR, RESULTING IN A SLOW WEAKENING TREN

REMARKS:
070300Z POSITION NEAR 16.9S 172.0E.
07APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 421
NM WEST OF SUVA, FIJI, HAS TRACKED EASTWARD AT 15 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED AND VISIBLE SATELLITE IMAGERY SHOWS THAT TC 25P HAS REI
NTENSIFIED, OR AT LEAST ARRESTED THE WEAKENING TREND FOR A SHORT TIME, WITH THE REAPPEARANCE OF A
PINHOLE EYE OVER THE PAST FEW HOURS. THE SYSTEM HAS MOISTENED SINCE THE PREVIOUS WARNING, PARTICUL
ARLY ON THE EASTERN SIDE, WHICH HAS ALLOWED FOR REGENERATION OF CONVECTION AROUND THE CORE OF THE
SYSTEM. A 0056Z GMI 37 GHZ MICROWAVE SHOWED THE REDEVELOPMENT OF AN EYEWALL SURROUNDING THE SMALL
EYE, WITH THE EXCEPTION OF THE EASTERN SIDE WHICH IS STILL SOMEWHAT DISORGANIZED AND RAGGED. THE I
NITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE PINHOLE EYE IN THE VISIBLE IMAGERY, SU
PPORTED BY THE MICROWAVE EYE FEATURE IN THE PREVIOUSLY NOTED GMI MICROWAVE IMAGERY. THE INITIAL IN
TENSITY OF 115 KNOTS IS ASSESSED WITH HIGH CONFIDENCE BASED ON DVORAK CURRENT INTENSITY ESTIMATES
OF T5.5 (102-115 KNOTS) FROM PGTW AND PHFO, AN ADVANCED DVORAK TECHNIQUE ESTIMATE OF T6.1 (117 KNO
TS) AND A SATELLITE CONSENSUS ESTIMATE OF 114 KNOTS. ENVRIONMENTAL ANALYSIS SHOWS THAT THE SYSTEM
REMAINS IN A FAVORABLE ENVIRONMENT, WITH LOW (5-10 KNOTS) VWS, WARM (28-29 DEG CELSIUS) SSTS, AND
STRONG, DIVERGENT EQUATORWARD AND EASTWARD UPPER-LEVEL OUTFLOW. TC 25P CONTINUES TRACKING ALONG TH
E SOUTHWESTERN PERIPHERY OF A DEEP-LAYER STR LOCATED FAR TO THE NORTHEAST, AND WILL CONTINUE TO TR
ACK SOUTHEAST WHILE ACCELERATING THROUGH THE FORECAST PERIOD. THE OVERALL ENVIRONMENT IS FORECAST
TO REMAIN FAVORABLE FOR THE NEXT 24 HOURS, THOUGH THE UPPER-LEVEL POINT SOURCE CURRENTLY OVER THE
SYSTEM WILL BEGIN TO MOVE AWAY SLOWLY, LEADING TO INCREASING SHEAR, RESULTING IN A SLOW WEAKENING
TREND THROUGH TAU 24. THEREAFTER, VWS BEGINS TO INCREASE DRAMATICALLY, WHILE OUTFLOW DECREASES, LE
ADING TO MORE RAPID WEAKENING THROUGH THE REMAINDER OF THE FORECAST. BY TAU 48, THE SYSTEM WILL BE
GIN TO INTERACT WITH THE DEEP WESTERLIES SOUTHEAST OF TONGA, AND WILL BEGIN TRANSITION TO AN EXTRA
TROPICAL CYCLONE, COMPLETING THE TRANSITION BY TAU 72. DYNAMIC MODEL GUIDANCE IS IN TIGHT AGREEMEN
T THROUGH TAU 36. WHILE ALL MODELS AGREE ON THE GENERAL TRACK SCENARIO, DISAGREEMENT IN THE SPEED
AND CURVE TOWARDS THE SOUTH BETWEEN MODELS INCRESAES AFTER TAU 48 WITH A 270NM DIFFERENCE BETWEEN
THE NAVGEM AND GFS OUTLIERS BY TAU 72. OVERALL THERE IS HIGH CONFIDENCE IN THE JTWC OFFICIAL FOREC
AST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070000Z IS 40 FEET. NEXT WARNINGS AT 070900Z, 071500

REMARKS:
062100Z POSITION NEAR 16.7S 170.4E.
06APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 507
NM WEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A WEAKENING SYSTEM, WITH THE EYE BECOMING MUCH SMALLER AND MORE RAGGED OVER THE PAST FEW HOURS.

REMARKS:
062100Z POSITION NEAR 16.7S 170.4E.
06APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 507
NM WEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A WEAKENING SYSTEM, WITH THE EYE BECOMING MUCH
SMALLER AND MORE RAGGED OVER THE PAST FEW HOURS. A 061706Z SSMIS
PASS SHOWED THAT WHILE THE MICROWAVE EYE IS STILL WELL DEFINED IN
THE UPPER LEVELS AS SHOWN IN THE 89 GHZ BAND, THE FEATURE HAS BECOME
MUCH LESS DEFINED IN THE LOWER LEVELS AS SHOWN IN THE 37 GHZ BAND.
WATER VAPOR IMAGERY ALSO INDICATES DRIER MID-LEVEL AIR WRAPPING
AROUND THE WESTERN PERIPHERY OF THE SYSTEM, EVEN ENTRAINING AROUND
TO THE EASTERN SIDE AS WELL, AS SHOWN BY A BAND OF WEAK TO NO
CONVECTION AND A WEAKENING OF THE EYEWALL ON THE NORTHEAST SIDE OF
THE CORE. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED
ON THE SMALL EYE IN BOTH THE INFRARED AND MICROWAVE IMAGERY NOTED
ABOVE. THE INITIAL INTENSITY OF 135 KNOTS IS ASSESSED WITH MODERATE
CONFIDENCE, HEDGED SLIGHTLY HIGHER THAN DVORAK CURRENT INTENSITY
ESTIMATES OF T6.0 (115-140 KTS) FROM PGTW AND PHFO, WITH AN ADVANCED
DVORAK TECHNIQUE ESTIMATE OF T7.1 (142 KNOTS). ENVIRONMENTAL
ANALYSIS REVEALS THAT TC 25P REMAINS IN AN OVERALL FAVORABLE
ENVIRONMENT WITH LOW (5-10 KT) VWS, WARM (28-29 DEG C) SSTS AND
ROBUST OUTFLOW PROVIDED BY AN UPPER LEVEL POINT SOURCE ON TOP OF THE
SYSTEM. HOWEVER, DRY MID-LEVEL AIR IS STARTING TO MAKE AN IMPACT ON
THE STORM, WRAPPING IN TOWARDS THE CORE AND WEAKENING CONVECTION.
THROUGH THE FORECAST PERIOD, TC 25P WILL CONTINUE TRACKING
SOUTHEASTWARD ALONG THE SOUTHWEST PERIPHERY OF AN ELONGATED STR
LOCATED TO THE NORTHEAST. AS THE UPPER-LEVEL GRADIENT TIGHTENS IN
RESPONSE TO THE APPROACH OF A MID-LATITUDE TROUGH, TC 25P WILL
STEADILY ACCELERATE TROUGH THE FORECAST PERIOD. AS THE SYSTEM
ACCELERATES SOUTHEASTWARD, VWS IS FORECAST TO INCREASE WHILE SSTS
DECREASE AND DRY AIR CONTINUES TO ENTRAIN INTO THE SYSTEM, COMBINING
TO RAPIDLY WEAKEN TC 25P THROUGH THE FORECAST PERIOD. ADDITIONALLY,
AS THE SYSTEM APPROACHES 25-30 DEG LATITUDE, IT WILL BEGIN TO
INTERACT WITH THE DEEP WESTERLY FLOW AND BECOME FULLY EXTRATROPICAL
BY TAU 96 AS IT RACES OFF TO THE SOUTHEAST AHEAD OF A DEEP MID-
LATITUDE TROUGH. NUMERICAL MODEL GUIDANCE IS IN TIGHT AGREEMENT
THROUGH TAU 48, WITH SOMEWHAT INCREASED DIVERGENCE THEREAFTER. ALL
MODELS AGREE ON THE GENERAL TRACK SCENARIO, ONLY DISAGREEING ON THE
AMOUNT OF SOUTHWARD TRACK COMPONENT AS THE SYSTEM BECOMES
EXTRATROPICAL, LEADING TO OVERALL HIGH CONFIDENCE IN THE JTWC
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061800Z IS 45
FEET. NEXT WARNINGS AT 070300Z, 070900Z, 071500Z AND 072100Z.//

REMARKS:
061500Z POSITION NEAR 16.2S 169.4E.
06APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 106
NM NORTH-NORTHEAST OF PORT VILA, VANUATU, HAS TRACKED EASTWARD AT
10 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) SHOWS TC 25P HAS MAINTAINED A WELL DEFINED 10NM EYE WITH ASYMMETRIC DEEP CONVECTION THAT HAS SHIFTED TO THE WEST. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE FEATURE IN EIR. THE INITIAL INTENSITY IS BASED ON THE DVORAK ESTIMATE OF T7.0 (140 KNOTS) FROM PGTW AND A 061210Z ADVANCED DVORAK TECHNIQUE ESTIMATE OF 152 KNOTS. ENVIRONMENTAL ANALYSIS INDICATES A VERY FAVORABLE ENVIRONMENT WITH LOW (05-10 KNOT) VERTICAL WIND SHEAR (VWS), STRONG POLEWARD OUTFLOW, AND VERY WARM (29-30 DEGREES CELSIUS) SEA SURFACE TEMPERATURES (SST). TC 25P WILL CONTINUE TO TRACK ALONG THE SOUTWEST PERIPHERY OF THE SUBTROPICAL RIDGE TO THE NORTHEAST. THE STRONG POLEWARD OUTFLOW AND WARM SST, WILL GRADUALLY BE TEMPERED BY INCREASING VWS AFTER TAU 48 WHICH WILL WEAKEN THE CYCLONE DOWN TO 70 KNOTS BY TAU 96. BY TAU 72, TC HAROLD WILL BEGIN EXTRATROPICAL TRANSITION AS TRACK SPEED RAPIDLY INCERASES, BECOMING FULLY EXTRATROPICAL BY TAU 96. INTENSITY GUIDANCE IS IN FAIR AGREEMENT OVER THE NEXT 48 HOURS, BECOMING MORE CONCLUSIVE AS VWS BECOMES MORE PREDOMINATE. NUMERICAL TRACK GUIDANCE MODELS ARE IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE IN THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061200Z IS 50 FEET. NEXT WARNINGS AT 062100Z, 070300Z, 070900Z AND 071500Z.//

REMARKS:
060300Z POSITION NEAR 15.6S 167.1E.
06APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
161 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS THE SYSTEM HAS MADE
LANDFALL OVER VANUATU JUST SOUTH OF ELIA. THE CYCLONE HAS WEAKENED
SLIGHTLY BUT REMAINS VERY INTENSE AS IT MAINTAINED A SYMMETRIC CENTRAL DEEP OVERCAST AND A WELL-DEFINED 15NM EYE IN THE MSI LOOP. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE
FEATURE, WITH MINOR ADJUSTMENT FOR A FORWARD SLANT. THE INITIAL
INTENSITY IS BASED ON THE DVORAK ESTIMATE OF T6.0/115KTS FROM PGTW
AND REFLECTS THE SLIGHT WEAKENING. ENVIRONMENTAL ANALYSIS INDICATES
LOW (10-15KT)VERTICAL WIND SHEAR (VWS), STRONG POLEWARD OUTFLOW, AND
VERY WARM SST (30C). TC 25P HAS BEGUN TO TRACK MORE POLEWARD AS THE
SUBTROPICAL RIDGE TO THE NORTHEAST ASSUMED STEERING. INCREASING VWS,
TEMPERED BY THE POLEWARD OUTFLOW AND WARM SST, WILL GRADUALLY WEAKEN
THE CYCLONE DOWN TO 60KTS BY TAU 96. CONCURRENTLY, BY TAU 48, TC
HAROLD WILL BEGIN SUBTROPICAL TRANSITION, BECOMING SUBTROPICAL BY TAU
96. NUMERICAL MODELS ARE IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE
IN THE JTWC TRACK FORECAST. NEXT WARNINGS AT 060900Z, 061500Z,
062100Z AND 070300Z.//

REMARKS:
060300Z POSITION NEAR 15.6S 167.1E.
06APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
161 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS THE SYSTEM HAS MADE
LANDFALL OVER VANUATU JUST SOUTH OF ELIA. THE CYCLONE HAS WEAKENED
SLIGHTLY BUT REMAINS VERY INTENSE AS IT MAINTAINED A SYMMETRIC CENTRAL DEEP OVERCAST AND A WELL-DE
FINED 15NM EYE IN THE MSI LOOP. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE E
YE
FEATURE, WITH MINOR ADJUSTMENT FOR A FORWARD SLANT. THE INITIAL
INTENSITY IS BASED ON THE DVORAK ESTIMATE OF T6.0/115KTS FROM PGTW
AND REFLECTS THE SLIGHT WEAKENING. ENVIRONMENTAL ANALYSIS INDICATES
LOW (10-15KT)VERTICAL WIND SHEAR (VWS), STRONG POLEWARD OUTFLOW, AND
VERY WARM SST (30C). TC 25P HAS BEGUN TO TRACK MORE POLEWARD AS THE
SUBTROPICAL RIDGE TO THE NORTHEAST ASSUMED STEERING. INCREASING VWS,
TEMPERED BY THE POLEWARD OUTFLOW AND WARM SST, WILL GRADUALLY WEAKEN
THE CYCLONE DOWN TO 60KTS BY TAU 96. CONCURRENTLY, BY TAU 48, TC
HAROLD WILL BEGIN SUBTROPICAL TRANSITION, BECOMING SUBTROPICAL BY TAU
96. NUMERICAL MODELS ARE IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE
IN THE JTWC TRACK FORECAST. NEXT WARNINGS AT 060900Z, 061500Z,
062100Z AND 070300Z.//

REMARKS:
052100Z POSITION NEAR 15.3S 166.4E.
05APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
192 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
NORTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY SHOWS THE SYSTEM HAS LINGERED AND JOGGED
SLIGHTLY EASTWARD AS IT REGAINED A SYMMETRIC CENTRAL DEEP OVERCAST
AND A 16NM EYE. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE
BASED ON THE EYE IN THE IR THAT LINED UP WELL WITH A MICROWAVE EYE IN
THE 1719Z SSMIS COLORIZED 37GHZ IMAGE. THE INITIAL INTENSITY IS BASED
ON THE DVORAK ESTIMATE OF T6.5/127KTS FROM PGTW AND REFLECTS THE
REINTENSIFICATION. ENVIRONMENTAL ANALYSIS INDICATES LOW
(10-15KT)VERTICAL WIND SHEAR (VWS), STRONG POLEWARD OUTFLOW, AND VERY
WARM SST (30C). TC 25P HAS TRACKED EASTWARD UNDER THE INFLUENCE OF A
NEAR EQUATORIAL RIDGE TO THE NORTH. THE SUBTROPICAL RIDGE TO THE
NORTHEAST IS EXPECTED TO BUILD AND ASSUME STEERING FROM HERE ONWARD.
INCREASING VWS, TEMPERED BY THE POLEWARD OUTFLOW AND WARM SST, WILL
GRADUALLY WEAKEN THE CYCLONE DOWN TO 60KTS BY TAU 96. CONCURRENTLY,
BY TAU 48, TC HAROLD WILL BEGIN SUBTROPICAL TRANSITION, BECOMING
SUBTROPICAL BY TAU 96. NUMERICAL MODELS ARE IN GOOD AGREEMENT,
HOWEVER, GIVEN THE UNCERTAINTY IN THE INITIAL STORM MOTION FOLLOWING
A TRANSITION IN THE STEERING MECHANISM, THERE IS LOW CONFIDENCE IN
THE INITIAL PORTION OF THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 051800Z IS 45 FEET. NEXT WARNINGS AT 060300Z, 060900Z,
061500Z AND 062100Z.//

NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EASTWARD AT 01
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY SHOWS A WOBBLY, YET TIGHTLY WRAPPED EYE. THE INITIAL POSITION IS BASED ON THE 10NM EYE SEEN IN EIR. THE INITIAL INTENSITY IS HEDGED BETWEEN THE DVORAK INTENSITY ESTIMATE OF T6.0 (115 KNOTS) FROM PHFO, A T6.5 (127 KNOTS) FROM PGTW AND A 051240Z ADT ESTIMATE OF 130 KNOTS. INTENSITY GUIDANCE IS IN OVERALL FAIR AGREEMENT. CURRENTLY, THE ENVIRONMENT REMAINS FAVORABLE WITH STRONG POLEWARD OUTFLOW, WARM SSTS (29C) AND LOW (05-10 KNOTS) VERTICAL WIND SHEAR (VWS). TC 25P IS EXPECTED TO CONTINUE ON ITS CURRENT TRACK ALONG THE SOUTHWEST PERIPHERY OF A DEEP-LAYERED SUBTROPICAL RIDGE TO THE NORTHEAST. INCREASING VWS, SUBSIDENCE, AND LATER ON, COOLING SSTS, TEMPERED BY THE POLEWARD OUTFLOW, WILL GRADUALLY WEAKEN THE SYSTEM DOWN TO 60 KNOTS BY TAU 96. BY TAU 72, THE SYSTEM WILL BEGIN SUBTROPICAL TRANSITION, BECOMING SUBTROPICAL BY TAU 96. NUMERICAL MODELS ARE IN GOOD AGREEMENT THROUGH TAU 72, WITH CROSS TRACK SPREAD INCREASING TO 300NM BY TAU 96, LENDING OVERALL HIGH CONFIDENCE TO THE JTWC TRACK FORECAST THAT IS LAID CLOSE TO THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051200Z IS 36 FEET. NEXT WARNINGS AT 052100Z, 060300Z, 060900Z AND 061500Z.//

REMARKS:
050900Z POSITION NEAR 15.6S 165.6E.
05APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
204NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY SHOWS AN EYE HAS REFORMED AS UPPER LEVEL
OUTFLOW REMAINS STRONG. THE INITIAL POSITION IS BASED ON THE 10NM
EYE. THE INITIAL INTENSITY IS HEDGED BETWEEN THE DVORAK CURRENT
INTENSITY ESTIMATE OF T5.5 (102KTS) FROM PGTW AND NFFN AND THE
050626Z SATCON ESTIMATE OF 110 KNOTS. THE ENVIRONMENT REMAINS
CONDUCIVE FOR AN INTENSIFICATION AS WARM SSTS (29C) AND LOW VERTICAL
WIND SHEAR (VWS) PREVAIL. TC 25P IS EXPECTED TO CONTINUE ON ITS
CURRENT TRACK ALONG THE SOUTHWEST PERIPHERY OF A DEEP-LAYERED
SUBTROPICAL RIDGE TO THE NORTHEAST. INCREASING VWS, SUBSIDENCE, AND
LATER ON, COOLING SSTS, TEMPERED BY THE POLEWARD OUTFLOW, WILL
GRADUALLY WEAKEN THE SYSTEM DOWN TO 60KTS BY TAU 120. BY TAU 96, THE
SYSTEM WILL BEGIN SUBTROPICAL TRANSITION, BECOMING SUBTROPICAL BY
TAU 120. NUMERICAL MODELS ARE IN VERY GOOD AGREEMENT, LENDING HIGH
CONFIDENCE TO THE JTWC TRACK FORECAST THAT IS LAID CLOSE TO THE
MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 050600Z IS 35
FEET. NEXT WARNINGS AT 051500Z, 052100Z, 060300Z AND 060900Z.//

REMARKS:
050300Z POSITION NEAR 15.5S 166.0E.
05APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
195 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS CONVECTIVE TOP HAVE BEGUN TO WARM, AN
INDICATION OF WEAKENING. HOWEVER, A ROBUST POLEWARD OUTFLOW REMAINS.
THE INITIAL POSITION IS BASED ON A RAGGED MICROWAVE EYE IN THE
041858Z SSMIS COLORIZED 37GHZ IMAGE WITH FAIR CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON THE DVORAK ESTIMATE OF T5.5/102KTS FROM
PGTW. ENVIRONMENTAL ANALYSIS INDICATES STRONG POLEWARD OUTFLOW AND
WARM SSTS (29C) THAT IS OFFSET BY SUBSIDENCE AND INCREASING (20KTS+)
VERTICAL WIND SHEAR(VWS). TC 25P IS EXPECTED TO CONTINUE ON ITS
CURRENT TRACK ALONG THE SOUTHWEST PERIPHERY OF A DEEP-LAYERED
SUBTROPICAL RIDGE TO THE NORTHEAST. INCREASING VWS, SUBSIDENCE, AND
LATER ON, COOLING SSTS, TEMPERED BY THE POLEWARD OUTFLOW, WILL
GRADUALLY WEAKEN THE SYSTEM DOWN TO 60KTS BY TAU 120. CONCURRENTLY,
BY TAU 96, THE SYSTEM WILL BEGIN SUBTROPICAL TRANSITION, BECOMING
SUBTROPICAL BY TAU 120. NUMERICAL MODELS ARE IN VERY GOOD AGREEMENT,
LENDING HIGH CONFIDENCE TO THE JTWC TRACK FORECAST THAT IS LAID CLOSE
TO THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 050000Z IS
28 FEET. NEXT WARNINGS AT 050900Z, 051500Z, 052100Z AND 060300Z.//

REMARKS:
042100Z POSITION NEAR 15.0S 165.6E.
04APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
233 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
05 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS THE SYSTEM HAS MAINTAINED DEEP CENTRAL
CONVECTION AND ROBUST POLEWARD OUTFLOW. HOWEVER, SUBSIDENCE
ASSOCIATED WITH AN APPROACHING MID-LATITUDE TROUGH HAS SUPPRESSED
SOME OF THE CONVECTION ALONG THE WESTERN FLANK. THE INITIAL POSITION
IS BASED ON A MICROWAVE EYE IN THE 041438Z GCOMW1 COLORIZED 36GHZ
IMAGE WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS BASED ON THE
DVORAK ESTIMATE OF T6.0/115KTS FROM PGTW. ENVIRONMENTAL ANALYSIS
INDICATES STRONG POLEWARD OUTFLOW AND WARM SSTS (29C) THAT IS OFFSET
BY SUBSIDENCE AND INCREASING (20KTS+) VERTICAL WIND SHEAR(VWS). TC
25P IS EXPECTED TO CONTINUE ON ITS CURRENT TRACK ALONG THE SOUTHWEST
PERIPHERY OF A DEEP-LAYERED SUBTROPICAL RIDGE TO THE NORTHEAST. TC
HAROLD HAS PEAKED INTENSITY. INCREASING VWS, SUBSIDENCE, AND LATER
ON, COOLING SSTS WILL GRADUALLY WEAKEN THE SYSTEM DOWN TO 65KTS BY
TAU 120. CONCURRENTLY, BY TAU 96, THE SYSTEM WILL BEGIN SUBTROPICAL
TRANSITION, BECOMING SUBTROPICAL BY TAU 120. NUMERICAL MODELS ARE IN
VERY GOOD AGREEMENT WITH MINOR SPREADING LENDING HIGH CONFIDENCE TO
THE JTWC TRACK FORECAST THAT IS LAID CLOSE TO THE CONSENSUS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 041800Z IS 30 FEET. NEXT WARNINGS AT
050300Z, 050900Z, 051500Z AND 052100Z.//

REMARKS:
041500Z POSITION NEAR 14.7S 165.2E.
04APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 262
NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS THAT THE EYE HAS BEEN SUBSUMED INTO A LARGE
MASS OF CENTRAL CONVECTION. THE INITIAL POSITION IS BASED WITH FAIR
CONFIDENCE ON EXTRAPOLATION FROM THE AMBIGUITIES FROM A 041014Z
METOP-B ASCAT PASS. THE INITIAL INTENSITY IS ASSESSED AT 115 KNOTS,
IN AGREEMENT WITH DVORAK CURRENT INTENSITY ESTIMATES OF T6.0 (115
KTS) FROM PGTW, PHFO, AND THE ADVANCED DVORAK TECHNIQUE.
ENVIRONMENTAL ANALYSIS INDICATES THAT TC 25P LIES IN A HIGHLY
FAVORABLE ENVIRONMENT, WITH VERY ROBUST DIVERGENT OUTFLOW, WARM (29-
30 DEG CELSIUS) SSTS, AND LOW TO MODERATE (15-20 KNOTS) VERTICAL
WIND SHEAR (VWS), WITH A RELATIVE SHEAR VALUE MUCH LOWER DUE TO STORM
MOTION AND SHEAR VECTORS BEING IN PHASE. WIND RADII HAVE BEEN
ADJUSTED BASED ON THE AFOREMENTIONED ASCAT PASS. TC 25P IS TRACKING
SLOWLY SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF A NEAR-
EQUATORIAL RIDGE TO THE EAST. AN EXTENSION OF THE SUBTROPICAL RIDGE
WILL BUILD IN TO THE SOUTHEAST OF TC 25P OVER THE NEXT 24-36 HOURS,
WHICH WILL IN TURN LEAD TO VERY SLOW, NEARLY QUASI-STATIONARY SOUTH-
SOUTHEASTWARD MOVEMENT. BEYOND TAU 36, THE AFOREMENTIONED EXTENSION
OF THE STR WEAKENS, ALLOWING TC 25P TO ACCELERATE SOUTHEASTWARD
THROUGH THE END OF THE FORECAST PERIOD. TC 25P IS FORECAST TO
SLIGHTLY INTENSIFY FURTHER TO 120 KTS IN THE NEXT 12 HOURS AS IT
TAPS INTO HIGHLY DIVERGENT UPPER LEVEL FLOW WHILE REMAINING IN A
RELATIVELY LOW VWS ENVIRONMENT. HOWEVER, QUASI-STATIONARY MOVEMENT
IN A REGION OF MIDDLING OCEAN HEAT CONTENT (OHC) WATER AND SOME DRY
AIR INGESTION THAT IS EVIDENT IN THE EIR LOOP AND TOTAL PRECIPITABLE
WATER ANIMATION WILL COMPETE WITH THE ROBUST OUTFLOW TO LIMIT MUCH
FURTHER INTENSIFICATION AND BEGIN A WEAKENING TREND AFTER TAU 24.
AFTER TAU 48, THE ENVIRONMENT WILL FURTHER DETERIORATE AS THE SYSTEM
EXPERIENCES INCREASING VWS, CONVERGENCE ALOFT, AND DECREASING SSTS.
BY TAU 96, THE SYSTEM WILL BEGIN TO INTERACT WITH MID-LATITUDE
WESTERLIES AND BEGIN SUBTROPICAL TRANSITION. NUMERICAL GUIDANCE ALL
AGREE ON THE GENERAL SOUTHEASTWARD TRACK AND SLOW FORWARD MOTION
THROUGH TAU 48, BUT DIFFER ON THE DEGREE, WITH SOME MODELS
INDICATING A MOVEMENT DUE SOUTH OR EVEN SOUTHWEST AT ONE OR TWO
KNOTS BEFORE TURNING SOUTHEAST, WHILE OTHERS MOVE STRAIGHT SOUTHEAST
AT THREE TO FOUR KNOTS THROUGH THIS PERIOD. BEYOND TAU 48, MODELS
COME INTO MUCH BETTER AGREEMENT ON BOTH THE TRACK AND FORWARD
MOTION. THE JTWC FORECAST TRACK DRIFTS SLOWLY SOUTHEASTWARD BEFORE
ACCELERATING SOUTHEASTWARD AFTER TAU 48. DUE TO THE OVERALL HIGH
UNCERTAINTY IN THE GUIDANCE IN THE FIRST 48 HOURS AND THE GENERAL
UNCERTAINTY IN THE STEERING ENVIRONMENT, THERE IS LOW CONFIDENCE IN
THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041200Z
IS 30 FEET. NEXT WARNINGS AT 042100Z, 050300Z, 050900Z AND 051500Z.//

REMARKS:
040900Z POSITION NEAR 14.4S 164.9E.
04APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 287
NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
07 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS AN INTENSE SYSTEM WITH DEEPENING CONVECTION AND VERY
COLD CLOUD TOPS SURROUNDING A PINHOLE EYE THAT IS FILLING WITH
CLOUDS. THE INITIAL POSITION IS BASED WITH HIGH CONFIDENCE ON THE EYE
IN MSI IMAGERY AND SUPPORTED BY A 040620Z SSMIS 37GHZ IMAGE. THE
INITIAL INTENSITY IS ASSESSED AT 110 KNOTS, HEDGED SLIGHTLY UNDER
PHFO AND PGTW DVORAK CURRENT INTENSITY (CI) ESTIMATES OF T6.0 (115
KTS) BUT IN LINE WITH THE ADVANCED DVORAK TECHNIQUE CI OF T5.8 (110
KTS). ENVIRONMENTAL ANALYSIS INDICATES THAT TC 25P LIES IN A HIGHLY
FAVORABLE ENVIRONMENT, WITH VERY ROBUST DIVERGENT OUTFLOW, WARM (29-
30 DEG CELSIUS) SSTS AND LOW TO MODERATE (15-20 KNOTS) VERTICAL WIND
SHEAR (VWS), WITH A RELATIVE SHEAR VALUE MUCH LOWER DUE TO STORM
MOTION AND SHEAR VECTORS BEING IN PHASE. TC 25P IS TRACKING SLOWLY
SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF A NEAR-EQUATORIAL RIDGE
TO THE EAST. AN EXTENSION OF THE SUBTROPICAL RIDGE WILL BUILD IN TO
THE SOUTHEAST OF TC 25P OVER THE NEXT 24-36 HOURS, WHICH WILL IN TURN
LEAD TO VERY SLOW, NEARLY QUASI-STATIONARY SOUTH-SOUTHEASTWARD
MOVEMENT. BEYOND TAU 48, THE AFOREMENTIONED EXTENSION OF THE STR
WEAKENS, ALLOWING TC 25P TO ACCELERATE SOUTHEASTWARD THROUGH THE END
OF THE FORECAST PERIOD. TC 25P IS FORECAST TO SLIGHTLY INTENSIFY
FURTHER TO 120 KTS IN THE NEXT 12 HOURS AS IT TAPS INTO HIGHLY
DIVERGENT UPPER LEVEL FLOW WHILE REMAINING IN A RELATIVELY LOW VWS
ENVIRONMENT. HOWEVER, QUASI-STATIONARY MOVEMENT IN A REGION OF
MIDDLING OCEAN HEAT CONTENT (OHC) WATER WILL COMPETE WITH THE ROBUST
OUTFLOW TO LIMIT MUCH FURTHER INTENSIFICATION AND BEGIN A WEAKENING
TREND AFTER TAU 24. AFTER TAU 48, THE ENVIRONMENT WILL FURTHER
DETERIORATE AS THE SYSTEM EXPERIENCES INCREASING VWS AND CONVERGENCE
ALOFT, AND DECREASING SSTS. BY TAU 96, THE SYSTEM WILL BEGIN TO
INTERACT WITH MID-LATITUDE WESTERLIES AND BEGIN SUBTROPICAL
TRANSITION. NUMERICAL GUIDANCE ALL AGREE ON THE GENERAL SOUTHEASTWARD
TRACK AND SLOW FORWARD MOTION THROUGH TAU 48, BUT DIFFER ON THE
DEGREE, WITH SOME MODELS INDICATING A MOVEMENT DUE SOUTH OR EVEN
SOUTHWEST AT ONE OR TWO KNOTS BEFORE TURNING SOUTHEAST, WHILE OTHERS
MOVE STRAIGHT SOUTHEAST AT THREE TO FOUR KNOTS THROUGH THE ENTIRE
FORECAST. BEYOND TAU 48, MODELS COME INTO MUCH BETTER AGREEMENT ON
BOTH THE TRACK AND FORWARD MOTION. THE JTWC FORECAST TRACK DRIFTS
SLOWLY SOUTHEASTWARD BEFORE ACCELERATING SOUTHEASTWARD AFTER TAU 72.
DUE TO THE OVERALL HIGH UNCERTAINTY IN THE GUIDANCE IN THE FIRST 48
HOURS AND THE GENERAL UNCERTAINTY IN THE STEERING ENVIRONMENT, THERE
IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 040600Z IS 30 FEET. NEXT WARNINGS AT 041500Z, 042100Z,
050300Z AND 050900Z.

NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY CONFIR
MS THAT TC HAROLD IS UNDERGOING A PERIOD OF RAPID INTENSIFICATION, WITH DEEP CONVECTIVE BANDS WITH
VERY COLD CLOUD TOPS WRAPPING INTO A PINHOLE EYE, WHICH HAS DEVELOPED OVER THE PAST FEW HOURS. TH
ERE HAS BEEN NO GOOD MICROWAVE PASS SINCE 031911Z, BUT THE INITIAL POSITION IS PLACED WITH HIGH CO

IS ASSESSED AT 90 KNOTS USING A COMBINATION OF AGENCY DVORAK CURRENT INTENSITY ESTIMATES OF T5.0
(90 KNOTS) FROM ALL AGENCIES (PGTW/PHFO/NFFN), AND AN ADVANCED DVORAK TECHNIQUE ESTIMATE OF T4.8.
ENVIRONMENTAL ANALYSIS INDICATES THAT TC 25P LIES IN A HIGHLY FAVORABLE ENVIRONMENT, WITH VERY ROB
UST DIRVERGENT OUTFLOW, WARM (29-30 DEG CELSIUS) SSTS AND LOW TO MODERATE (15-20 KNOTS) VWS, WITH
A RELATIVE SHEAR VALUE MUCH LOWER DUE TO STORM MOTION AND SHEAR VECTORS BEING IN PHASE. TC 25P HAS
SLOWED SIGNFICANTLY OVER THE PAST SIX HOURS, DUE TO THE DEVELOPMENT OF AN EXTENSION OF THE STR NO

REMARKS:
040300Z POSITION NEAR 14.1S 164.1E.
04APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 337
NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY CONFIRMS THAT TC HAROLD IS UNDERGOING
A PERIOD OF RAPID INTENSIFICATION, WITH DEEP CONVECTIVE BANDS WITH
VERY COLD CLOUD TOPS WRAPPING INTO A PINHOLE EYE, WHICH HAS DEVELOPED
OVER THE PAST FEW HOURS. THERE HAS BEEN NO GOOD MICROWAVE PASS SINCE
031911Z, BUT THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED
ON THE PINHOLE EYE FEATURE IN THE VISIBLE AND INFRARED BANDS. THE
INITIAL INTENSITY IS ASSESSED AT 90 KNOTS USING A COMBINATION OF
AGENCY DVORAK CURRENT INTENSITY ESTIMATES OF T5.0 (90 KNOTS) FROM ALL
AGENCIES (PGTW/PHFO/NFFN), AND AN ADVANCED DVORAK TECHNIQUE ESTIMATE
OF T4.8. ENVIRONMENTAL ANALYSIS INDICATES THAT TC 25P LIES IN A HIGHLY
FAVORABLE ENVIRONMENT, WITH VERY ROBUST DIRVERGENT OUTFLOW, WARM (29-
30 DEG CELSIUS) SSTS AND LOW TO MODERATE (15-20 KNOTS) VWS, WITH A
RELATIVE SHEAR VALUE MUCH LOWER DUE TO STORM MOTION AND SHEAR VECTORS
BEING IN PHASE. TC 25P HAS SLOWED SIGNFICANTLY OVER THE PAST SIX
HOURS, DUE TO THE DEVELOPMENT OF AN EXTENSION OF THE STR NOSING
SOUTHWESTWARD TO THE EAST OF THE SYSTEM, EFFECTIVELY LIMITING
EASTEWARD MOVEMENT OF TC 25P. THIS RIDGE IS FORECAST TO FURTHER
STRENGTHEN OVER THE NEXT 24-36 HOURS, WHICH WILL IN TURN LEAD TO VERY
SLOW, NEARLY QUASI-STATIONARY MOVEMENT TOWARDS THE SOUTH-SOUTHEAST OF
TC 25P. BEYOND TAU 48 THE AFOREMENTIONED EXTENSION OF THE STR WEAKENS
AND THE STR ITSELF REORIENTS TO A NORTHWEST-SOUTHEAST ORIENTATION,
ALLOWING TC 25P TO ACCELERATE SOUTHWEASTWARD THROUGH THE END OF THE
FORECAST PERIOD. TC 25P IS FORECAST TO CONTINUE TO RAPIDLY INTENSIFY
OVER THE NEXT 24-36 AS IT TAPS INTO HIGHLY DIVERGENT UPPER LEVEL FLOW
WHILE REMAINING IN A RELATIVELY LOW VWS ENVIRONMENT OVER VERY WARM
WATERS. AFTER PEAKING OUT AT 120 KNOTS BY TAU 48 THE ENVIRONMENT WILL
SLOWLY DETERIORATE AS THE SYSTEM EXPERIENCES INCREASING VWS AND
CONVERGENCE ALOFT, AND DECREASING SSTS. BY TAU 96, THE SYSTEM WILL
BEGIN TO INTERACT WITH MID-LATITUDE WESTERLIES AND BEGIN SUBTROPICAL
TRANSITION. NUMERICAL GUIDANCE ALL AGREE ON THE GENERAL SOUTHEASTWARD
TRACK AND SLOW FORWARD MOTION THROUGH TAU 48, BUT DIFFER ON THE
DEGREE, WITH SOME MODELS INDICATING A MOVEMENT DUE SOUTH OR EVEN
SOUTHWEST AT ONE OR TWO KNOTS BEFORE TURNING SOUTHEAST, WHILE OTHERS
MOVE STRAIGHT SOUTHEAST AT THREE TO FOUR KNOTS THROUGH THE ENTIRE
FORECAST. BEYOND TAU 48, MODELS COME INTO MUCH BETTER AGREEMENT ON
BOTH THE TRACK AND FORWARD MOTION. THE JTWC FORECAST FAVORS THE MORE
SOUTHWARD TRACK THROUGH TAU 48 AT ABOUT THREE KNOTS, BEFORE TURNING
SOUTHEAST AND ACCELERATING AFTER TAU 48. DUE TO THE OVERALL HIGH
UNCERTAINTY IN THE GUIDANCE IN THE FIRST 48 HOURS AND THE GENERAL
UNCERTAINTY IN THE STEERING ENVIRONMENT, THERE IS LOW CONFIDENCE IN
THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040000Z IS
28 FEET. NEXT WARNINGS AT 040900Z, 041500Z, 042100Z AND 050300Z.//

032100Z POSITION NEAR 13.7S 164.1E.
03APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 362
NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS THAT TC 25P C
ONTINUES TO RAPIDLY CONSOLIDATE AND STEADILY INTENSIFY AS IT TRACKS THROUGH THE OPEN WATERS BETWEE
N THE SOLOMON ISLANDS AND VANUATU. A 031743Z SSMIS 91 GHZ COLORPCT MICROWAVE IMAGE DEPICTS WELL DE
FINED CONVECTIVE BANDS WRAPPING INTO A DEVELOPING MICROWAVE EYE FEATURE, LENDING HIGH CONFIDENCE I
N THE INITIAL POSITION. THE INITIAL INTENSITY IS ASSESSED WITH MODERATE CONFIDENCE BASED ON THE SU
BJECTIVE DVORAK CURRENT INTENSITY ESTIMATES OF T3.5 FROM PGTW AND T4.0 FROM PHFO, SUPPORTED BY AN
ADVANCED DVORAK TECHNIQUE OF T4.6. ENVIRONMENTAL ANALYSIS INDICATES THAT TC 25P LIES IN A FAVORABL
E ENVIRONMENT FOR FURTHER INTENSIFICATION, WITH AN UPPER-LEVEL POINT SOURCE PROVIDING ROBUST OUTFL
OW, HIGH SSTS OF 29-30 DEG CELSIUS AND LOW-MODERATE (15-20 KNOTS) VWS, THOUGH THE RELATIVE VWS IS
SIGNIFICANTLY LOWER AS STORM MOTION IS IN PHASE WITH THE SHEAR VECTOR. THROUGH TAU 24, TC 25P IS
FORECAST TO TRACK SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A DEEP-LAYER STR LOCATED TO THE EA
ST. BETWEEN TAU 24 AND 48, THE SYSTEM WILL BECOME NEARLY QUASI-STATIONARY AS IT ENTERS A WEAK STEE
RING PATTERN, AS THE STR TO THE EAST RIDGES STRONGLY SOUTHWESTWARD AND EFFECTIVELY BLOCKS FURTHER
MOVEMENT TOWARDS THE SOUTHEAST FOR A SHORT PERIOD. AFTER TAU 48 AND THROUGH THE END OF THE FORECAS
T PERIOD, THIS RIDGE WEAKENS AHEAD OF AN APPROACHING DEEP LAYER TROUGH, WHILE A NEW NORTHWEST-SOUT
HEAST ORIENTED STR DEVELOPS NEAR SAMOA, ALLOWING TC 25P TO ACCELERATE SOUTHWEASTWARDS. THE SYSTEM
IS EXPECTED TO RAPIDLY INTENSIFY OVER THE NEXT 24 HOURS UNDER ROBUST UPPER-LEVEL OUTFLOW AND LOW V
WS, REACHING A PEAK OF 100 KNOTS BY TAU 72. THEREAFTER, INCREASING VWS, CONVERGENCE ALOFT AND COOL
ER SSTS WILL COMBINE TO RAPIDLY WEAKEN THE SYSTEM. NUMERICAL MODEL GUIDANCE IS SHOWING INCREASING
UNCERTAINTY WITH MODEL SPREAD INCREASING, PARTICULARLY IN THE FIRST 48 HOURS OF THE FORECAST DUE T
O THE COMPLEX NATURE OF THE NEAR-TERM STEERING ENVIRONMENT. AFTER TAU 48, THE MODEL GUIDANCE IS IN
MUCH BETTER AGREEMENT HOWEVER, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK DUE TO THE NEAR
-TERM UNCERTAINTY. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031800Z IS 22 FEET. NEXT WARNINGS AT 040300Z

REMARKS:
032100Z POSITION NEAR 13.7S 164.1E.
03APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 362
NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTHEASTWARD AT
11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS THAT TC 25P CONTINUES TO RAPIDLY CONSOLIDATE
AND STEADILY INTENSIFY AS IT TRACKS THROUGH THE OPEN WATERS BETWEEN
THE SOLOMON ISLANDS AND VANUATU. A 031743Z SSMIS 91 GHZ COLORPCT
MICROWAVE IMAGE DEPICTS WELL DEFINED CONVECTIVE BANDS WRAPPING INTO
A DEVELOPING MICROWAVE EYE FEATURE, LENDING HIGH CONFIDENCE IN THE
INITIAL POSITION. THE INITIAL INTENSITY IS ASSESSED WITH MODERATE
CONFIDENCE BASED ON THE SUBJECTIVE DVORAK CURRENT INTENSITY
ESTIMATES OF T3.5 FROM PGTW AND T4.0 FROM PHFO, SUPPORTED BY AN
ADVANCED DVORAK TECHNIQUE OF T4.6. ENVIRONMENTAL ANALYSIS INDICATES
THAT TC 25P LIES IN A FAVORABLE ENVIRONMENT FOR FURTHER
INTENSIFICATION, WITH AN UPPER-LEVEL POINT SOURCE PROVIDING ROBUST
OUTFLOW, HIGH SSTS OF 29-30 DEG CELSIUS AND LOW-MODERATE (15-20
KNOTS) VWS, THOUGH THE RELATIVE VWS IS SIGNIFICANTLY LOWER AS STORM
MOTION IS IN PHASE WITH THE SHEAR VECTOR. THROUGH TAU 24, TC 25P IS
FORECAST TO TRACK SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A
DEEP-LAYER STR LOCATED TO THE EAST. BETWEEN TAU 24 AND 48, THE
SYSTEM WILL BECOME NEARLY QUASI-STATIONARY AS IT ENTERS A WEAK
STEERING PATTERN, AS THE STR TO THE EAST RIDGES STRONGLY
SOUTHWESTWARD AND EFFECTIVELY BLOCKS FURTHER MOVEMENT TOWARDS THE
SOUTHEAST FOR A SHORT PERIOD. AFTER TAU 48 AND THROUGH THE END OF
THE FORECAST PERIOD, THIS RIDGE WEAKENS AHEAD OF AN APPROACHING DEEP
LAYER TROUGH, WHILE A NEW NORTHWEST-SOUTHEAST ORIENTED STR DEVELOPS
NEAR SAMOA, ALLOWING TC 25P TO ACCELERATE SOUTHWEASTWARDS. THE
SYSTEM IS EXPECTED TO RAPIDLY INTENSIFY OVER THE NEXT 24 HOURS UNDER
ROBUST UPPER-LEVEL OUTFLOW AND LOW VWS, REACHING A PEAK OF 100 KNOTS
BY TAU 72. THEREAFTER, INCREASING VWS, CONVERGENCE ALOFT AND COOLER
SSTS WILL COMBINE TO RAPIDLY WEAKEN THE SYSTEM. NUMERICAL MODEL
GUIDANCE IS SHOWING INCREASING UNCERTAINTY WITH MODEL SPREAD
INCREASING, PARTICULARLY IN THE FIRST 48 HOURS OF THE FORECAST DUE
TO THE COMPLEX NATURE OF THE NEAR-TERM STEERING ENVIRONMENT. AFTER
TAU 48, THE MODEL GUIDANCE IS IN MUCH BETTER AGREEMENT HOWEVER,
THERE IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK DUE TO THE NEAR-
TERM UNCERTAINTY. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031800Z IS 22
FEET. NEXT WARNINGS AT 040300Z, 040900Z, 041500Z AND 042100Z.//

REMARKS:
031500Z POSITION NEAR 13.0S 163.2E.
03APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
429 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY INDICATES THAT TC 25P IS CONSOLIDATING
RAPIDLY AS IT TRACKS AWAY FROM THE SOLOMON ISLANDS. A 031034Z MHS
89GHZ MICROWAVE IMAGE DEPICTS TIGHTLY-CURVED BANDING WRAPPING INTO A
MICROWAVE EYE FEATURE, WHICH SUPPORTS THE INITIAL POSITION WITH GOOD
CONFIDENCE. UPPER-LEVEL ANALYSIS REVEALS A VERY FAVORABLE
ENVIRONMENT WITH ROBUST POLEWARD OUTFLOW, LOW VERTICAL WIND SHEAR
AND WARM SST VALUES (30C). THE INITIAL INTENSITY IS ASSESSED AT 55
KNOTS BASED ON PGTW/KNES DVORAK INTENSITY ESTIMATES OF T3.5 (55
KNOTS). THE SYSTEM IS EXPECTED TO INTENSIFY THROUGH TAU 48 UNDER
PERSISTENT VERY FAVORABLE ENVIRONMENTAL CONDITIONS WITH SOME
POTENTIAL FOR RAPID INTENSIFICATION. THE SYSTEM IS EXPECTED TO PEAK
AT 90 KNOTS BY TAU 48 AS IT TRACKS GENERALLY SOUTHEASTWARD ALONG THE
WESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE
EAST. BY TAU 48, THE STEERING ENVIRONMENT IS EXPECTED TO WEAKEN AS A
DEEP MIDLATITUDE SHORTWAVE TROUGH APPROACHES FROM THE SOUTHWEST AND
THE STR TEMPORARILY BUILDS TO THE SOUTH. THIS WILL LEAD TO A SHORT
PERIOD OF SLOW, POSSIBLY QUASI-STATIONARY TRACK MOTION THROUGH TAU
60. NUMERICAL MODEL GUIDANCE DIVERGES DURING THIS PERIOD WITH
INCREASING UNCERTAINTY IN THE FORECAST TRACK. AFTER TAU 72, UPPER-
LEVEL SUBTROPICAL WESTERLIES ASSOCIATED WITH THE BROAD TROUGH ARE
EXPECTED TO STRENGTHEN OVER TC 25P, WHICH WILL SERVE TO ACCELERATE
THE SYSTEM EAST-SOUTHEASTWARD WITH STEADY WEAKENING DUE TO
CONVERGENCE ALOFT AND MODERATE BAROCLINICITY AS INDICATED IN THE
850MB TEMPERATURE FIELDS. OVERALL, THERE IS LOW CONFIDENCE IN THE
JTWC FORECAST TRACK DUE TO THE COMPLEX, EVOLVING STEERING PATTERN.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031200Z IS 17 FEET. NEXT
WARNINGS AT 032100Z, 040300Z, 040900Z AND 041500Z.//

REMARKS:
030900Z POSITION NEAR 11.8S 163.0E.
03APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
502 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
SOUTHEASTWARD AT 15 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY INDICATES THAT TC 25P IS BEGINNING TO
CONSOLIDATE AS IT TRACKS AWAY FROM THE SOLOMON ISLANDS. A 030801Z
SSMIS 91GHZ IMAGE DEPICTS TIGHTLY-CURVED BANDING WRAPPING INTO A
DEFINED LOW-LEVEL CIRCULATION CENTER. UPPER-LEVEL ANALYSIS REVEALS A
VERY FAVORABLE ENVIRONMENT WITH ROBUST POLEWARD OUTFLOW, LOW
VERTICAL WIND SHEAR AND WARM SST VALUES (30C). THE INITIAL INTENSITY
REMAINS ASSESSED AT 40 KNOTS BASED ON AN AVERAGE OF DVORAK INTENSITY
ESTIMATES RANGING FROM T2.5 TO T3.0 (35 TO 45 KNOTS). HOWEVER, THE
SYSTEM IS EXPECTED TO INTENSIFY AT A HIGHER-THAN-CLIMATOLOGICAL RATE
THROUGH TAU 48 UNDER PERSISTENT VERY FAVORABLE ENVIRONMENTAL
CONDITIONS WITH SOME POTENTIAL FOR RAPID INTENSIFICATION. THE SYSTEM
IS EXPECTED TO PEAK AT 80 KNOTS BY TAU 48 AS IT TRACKS GENERALLY
SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE
(STR) POSITIONED TO THE EAST. BY TAU 48, THE STEERING ENVIRONMENT IS
EXPECTED TO WEAKEN AS A DEEP MIDLATITUDE SHORTWAVE TROUGH APPROACHES
FROM THE SOUTHWEST AND THE STR TEMPORARILY BUILDS TO THE SOUTH. THIS
WILL LEAD TO A SHORT PERIOD OF SLOW, POSSIBLY QUASI-STATIONARY TRACK
MOTION THROUGH TAU 72. NUMERICAL MODEL GUIDANCE DIVERGES DURING THIS
PERIOD WITH INCREASING UNCERTAINTY IN THE FORECAST TRACK. AFTER TAU
72, UPPER-LEVEL SUBTROPICAL WESTERLIES ASSOCIATED WITH THE BROAD
TROUGH ARE EXPECTED TO STRENGTHEN OVER TC 25P, WHICH WILL SERVE TO
ACCELERATE THE SYSTEM EAST-SOUTHEASTWARD WITH STEADY WEAKENING DUE
TO CONVERGENCE ALOFT AND MODERATE BAROCLINICITY AS INDICATED IN THE
850MB TEMPERATURE FIELDS. OVERALL, THERE IS LOW CONFIDENCE IN THE
JTWC FORECAST TRACK DUE TO THE COMPLEX, EVOLVING STEERING PATTERN.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030600Z IS 14 FEET. NEXT
WARNINGS AT 031500Z, 032100Z, 040300Z AND 040900Z.//

REMARKS:
030300Z POSITION NEAR 10.8S 162.1E.
03APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
586 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
SOUTHEASTWARD AT 21 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS LOW LEVEL BANDING
WRAPPING UNDER FLARING DEEP CONVECTION. A 022227Z METOP-A ASCAT
IMAGE REVEALS STRONGER (35-44 KT) WINDS LOCATED TO THE NORTH OF
THE LOW LEVEL CIRCULATION CENTER (LLCC). BASED ON THIS ASCAT PASS
AND THE MSI, THERE IS GOOD CONFIDENCE IN THE INITIAL POSITION. THE
INITIAL INTENSITY IS SET AT 40 KTS BASED ON THE HIGHER WINDS TO
THE NORTH OF THE LLCC. FURTHERMORE, THE INTENSITY IS SUPPORTED BY
A 022345Z ADVANCED DVORAK TECHNIQUE INTENSITY ESTIMATE OF T2.8 (41
KTS) AND IS IN GOOD AGREEMENT WITH MULTI-AGENCY DVORAK CURRENT
INTENSITY ESTIMATES OF T2.5-3.0 (35-45 KTS) BY KNES, PHFO, AND
ABRF. TC 25P IS TRANSITING THROUGH AN OVERALL FAVORABLE
ENVIRONMENT OF LOW (LESS THAN 10 KTS) VERTICAL WIND SHEAR (VWS),
WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES, AND ESTABLISHED
POLEWARD AND EQUATORWARD OUTFLOW CHANNELS. THE SYSTEM IS TRACKING
EAST-SOUTHEASTWARD WITHIN THE PERIPHERY FLOW OF A WEAK NEAR
EQUATORIAL RIDGE LOCATED TO THE NORTH. BY TAU 12, A SUBTROPICAL
RIDGE TO THE EAST WILL TAKE OVER AS THE PRIMARY STEERING
MECHANISM. UNDER ITS INFLUENCE, TC 25P WILL TRACK SLOWLY
SOUTHEASTWARD AS THE SYSTEM INTENSIFIES. THERE IS A POSSIBILITY
FOR RAPID INTENSIFICATION IN THE EARLY TAUS OF THE FORECAST DUE TO
THE HIGHLY FAVORABLE ENVIRONMENT. AFTER TAU 48, TC 25P WILL TURN
AND ACCELERATE EAST-SOUTHEASTWARD AS IT INTERACTS WITH A PASSING
TROUGH AND THE MIDLATITUDE WESTERLIES. INCREASING VWS DUE TO THE
STRONG WESTERLY FLOW WILL BEGIN TO WEAKEN THE SYSTEM AFTER
TAU 96. NUMERICAL MODEL GUIDANCE IS IN FAIR AGREEMENT, WITH NAVGEM
AND GALWEM AS SOUTHERLY OUTLIERS AND UKMET AND UKMET ENSEMBLE AS
NORTHERLY OUTLIERS. OF NOTE, THE NAVGEM SOLUTION PRESENTS
SIGNIFICANTLY SLOWER ALONG-TRACK SPEEDS. THEREFORE, THE JTWC
FORECAST TRACK IS PLACED SLIGHTLY NORTH AND AHEAD OF THE MULTI-
MODEL CONSENSUS TO OFFSET THE NAVGEM OUTLIER. DUE TO THE SPREAD IN
MODEL SOLUTIONS, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030000Z IS 13 FEET. NEXT
WARNINGS AT 030900Z, 031500Z, 032100Z AND 040300Z.//

REMARKS:
022100Z POSITION NEAR 10.3S 160.0E.
02APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY
694 NM NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EASTWARD AT 15
KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY SHOWS A CONSOLIDATING SYSTEM WITH
CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER
(LLCC) THAT IS OBSCURED BY CONVECTION. THE INITIAL POSITION IS
BASED ON THE TURNING OBSERVED IN EIR IMAGERY ALONG WITH A 021755Z
SSMIS 91 GHZ MICROWAVE IMAGE WHICH DEPICTS BANDING WRAPPING INTO
THE LLCC AND A REGION OF DEEP CONVECTION LOCATED WITHIN THE
WESTERN SEMICIRCLE. BASED ON THIS MICROWAVE IMAGE AND THE EIR,
THERE IS GOOD CONFIDENCE IN THE INITIAL POSITION. THE INITIAL
INTENSITY OF 35 KTS IS PLACED IN THE MIDDLE OF THE MULTI-AGENCY
DVORAK CURRENT INTENSITY ESTIMATES OF T2.0-3.0 (30-45 KTS) BASED
ON THE IMPROVING CONVECTIVE STRUCTURE OF TC 25P. ENVIRONMENTAL
ANALYSIS REVEALS NEAR-RADIAL UPPER LEVEL OUTFLOW, LOW (5-10 KTS)
VERTICAL WIND SHEAR (VWS), AND WARM (29-30 CELSIUS) SEA SURFACE
TEMPERATURES (SST). THE SYSTEM IS CURRENTLY TRACKING EASTWARD
UNDER THE STEERING INFLUENCE OF A WEAK NEAR EQUATORIAL RIDGE
LOCATED TO THE NORTH. BY TAU 24, A SUBTROPICAL RIDGE TO THE EAST
WILL BUILD IN AND TAKE OVER THE STEERING, TURNING THE SYSTEM
SOUTHWARD WHILE SLOWING THE SYSTEM SPEED. AROUND TAU 72, TC 25P
WILL BEGIN TO INTERACT WITH THE MIDLATITUDE WESTERLIES, CAUSING
THE SYSTEM TO ACCELERATE ALONG AN EAST-SOUTHEASTWARD TRACK FOR THE
REMAINDER OF THE FORECAST. THROUGHOUT THE FORECAST, TC 25P IS
EXPECTED TO STEADILY INTENSIFY TO 85 KTS BY TAU 96, SUPPORTED BY
THE CONTINUED FAVORABLE ENVIRONMENT. NUMERICAL MODEL GUIDANCE IS
IN FAIR AGREEMENT, POSSIBLY DUE TO THE CURRENT WEAK STEERING
ENVIRONMENT. NAVGEM IS THE SOUTHERLY OUTLIER, TURNING TC 25P
POLEWARD BY TAU 12. CONVERSELY, THE UKMET AND UKMET ENSEMBLE
SOLUTIONS KEEP THE TRACK SLIGHTLY NORTH OF THE MODEL MAJORITY. DUE
TO THE SPREAD IN THE MODEL SOLUTIONS, THERE IS LOW CONFIDENCE IN
THE JTWC TRACK FORECAST WHICH IS PLACED SLIGHTLY NORTH OF THE
MULTI-MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 021800Z
IS 12 FEET. NEXT WARNINGS AT 030300Z, 030900Z, 031500Z AND
032100Z.
