REMARKS:
072100Z POSITION NEAR 24.7S 58.5E.
07MAR21. TROPICAL CYCLONE 25S (IMAN), LOCATED APPROXIMATELY 278 NM
SOUTH-SOUTHEAST OF ST DENIS, LA REUNION, HAS TRACKED EAST-
SOUTHEASTWARD AT 19 KNOTS OVER THE PAST SIX HOURS. THE CURRENT
POSITION AND INTENSITY ARE BASED ON A 071724Z METOP-B ASCAT PASS. TC
25S HAS CONSOLIDATED AND INTENSIFIED OVER THE PAST SIX HOURS WHILE
TRACKING EAST-SOUTHEASTWARD IN THE GRADIENT BETWEEN SUBTROPICAL
RIDGING TO THE NORTHEAST AND AN APPROACHING, DEEP-LAYER TROUGH TO
THE SOUTHWEST. THE SYSTEM IS EXPECTED TO CONTINUE TRACKING GENERALLY
SOUTHEASTWARD OVER THE NEXT 36 HOURS AND COMPLETE EXTRATROPICAL
TRANSITION AS THE APPROACHING TROUGH OVERTAKES THE SYSTEM. WHILE
POLEWARD OUTFLOW IS STRONG AND SEA SURFACE TEMPERATURE IS MARGINALLY
FAVORABLE AT AROUND 27C, VERTICAL WIND SHEAR IS VERY HIGH (GREATER
THAN 30 KNOTS). THE CONTINUED IMPACT OF STRONG VERTICAL WIND SHEAR
AND PASSAGE OVER COOL WATER ARE EXPECTED TO WEAKEN THE SYSTEM
THROUGHOUT THE FORECAST PERIOD, WITH NO OFFSETTING BAROCLINIC
SUPPORT FROM INTERACTION WITH THE AFOREMENTIONED TROUGH. NUMERICAL
MODEL GUIDANCE IS IN EXCELLENT AGREEMENT REGARDING THE FORECAST
TRACK, WHICH IS PLACED NEAR THE MULTI-MODEL CONSENSUS WITH HIGH
CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071800Z IS 20 FEET.
NEXT WARNINGS AT 080900Z AND 082100Z. REFER TO TROPICAL CYCLONE 24S
(HABANA) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.

REMARKS:

08MAR21. TROPICAL CYCLONE 25S (IMAN), LOCATED APPROXIMATELY 469 NM
SOUTH-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD
AT 29 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS THE SYSTEM HAS SIGNIFICANTLY ERODED AS IT
ACCELERATED SOUTH-SOUTHEASTWARD CHARACTERIZED BY UNRAVELED/DISPERSED
RAIN BANDS AND WARMED CONVECTIVE TOPS. THE INITIAL POSITION AND
INTENSITY ARE PLACED WITH HIGH CONFIDENCE BASED ON A 080437Z 25KM
RESOLUTION ASCAT BULLSEYE PASS. ANALYSIS INDICATES THE SYSTEM HAS
DRIFTED INTO COOLER (27C AND DECREASING) SEA SURFACE TEMPERATURES AND
STRONG (40KT+) VERTICAL WIND SHEAR. THE ASCAT PASS ALSO INDICATES THE
LOW LEVEL CIRCULATION HAS BECOME IRREGULAR AND GROSSLY ELONGATED WITH
THE 35KT WIND FIELD EXPANDED UP TO 100NM. TC PHASE CLASSIFICATION
WORKSHEET INDICATES THE SYSTEM IS NOW SUBTROPICAL AND WILL REMAIN SO
AS IT CONTINUES TO ACCELERATE POLEWARD. THIS IS THE FINAL WARNING ON
THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 080600Z IS 20 FEET. REFER TO TROPICAL
