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:
060900Z POSITION NEAR 15.9S 168.3E.
06APR20. TROPICAL CYCLONE 25P (HAROLD), LOCATED APPROXIMATELY 118
NM NORTH-NORTHWEST OF PORT VILA, VANUATU, HAS TRACKED EAST-
SOUTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) SHOWS TC 25P HAS MAINTAINED A WELL DEFINED 15NM EYE WITH SYMMETRIC DEEP CONVECTION THROUGHOUT. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE FEATURE AND A MICROWAVE EYE SEEN IN THE 060554Z SSMIS 91GHZ IMAGE. THE INITIAL INTENSITY IS BASED ON THE DVORAK ESTIMATE OF T7.0 (140 KNOTS) FROM PGTW AND A 060610Z ADVANCED DVORAK TECHNIQUE ESTIMATE OF 127 KNOTS. ENVIRONMENTAL ANALYSIS INDICATES A VERY FAVORABLE ENVIRONMENT WITH LOW (10-15 KNOT) VERTICAL WIND SHEAR (VWS), STRONG POLEWARD OUTFLOW, AND HOT (29-30 DEGREES CELSIUS) SEA SURFACE TEMPERATURES (SST). TC 25P HAS BEGUN TO TRACK MORE POLEWARD AS THE SUBTROPICAL RIDGE TO THE NORTHEAST HAS ASSUMED STEERING. THE STRONG POLEWARD OUTFLOW AND WARM SST, WILL GRADUALLY BE TEMPERED BY INCREASING VWS AFTER TAU 48 WHICH WILL WEAKEN THE CYCLONE DOWN TO 60KTS BY TAU 96. BY TAU 72, TC HAROLD WILL BEGIN SUBTROPICAL TRANSITION AS TRACK SPEED RAPIDLY INCERASES, BECOMING SUBTROPICAL 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 060600Z IS 45 FEET. NEXT WARNINGS AT 061500Z, 062100Z, 070300Z AND 070900Z.//
