REMARKS:
120300Z6 POSITION NEAR 24.1S7 53.6E4.
TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 190 NM
SOUTHWEST OF LA REUNION ISLAND, HAS TRACKED SOUTHEASTWARD AT 15
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
112330Z0 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 AND 102 KNOTS. A
112314Z2 TROPICAL RAINFALL MEASURING MISSION (TRMM) PASS REVEALS A
PARTIAL EYEWALL AND A LARGE BANDING FEATURE IN THE EASTERN SEMI-
CIRCLE. ANIMATED ENHANCED SATELLITE IMAGERY INDICATES THAT THE
SYSTEM HAS IMPROVED IN ORGANIZATION DURING THE PAST 6 HOURS. TC 18S
CONTINUES TO TRACK SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A
MID-LEVEL RIDGE TO THE EAST AND A MID-LEVEL TROUGH TO THE WEST.
UPPER LEVEL WESTERLIES ASSOCIATED WITH A LONGWAVE TROUGH ARE EVIDENT
IN THE LATEST IMAGERY AND ARE EXPECTED TO SLOWLY WEAKEN TC 18S AFTER
A BRIEF INTENSIFICATION PERIOD. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF GFDN, AVN, NOGAPS AND UK MET GLOBAL ARE IN GOOD
AGREEMENT. THE FORECAST TRACK IS BASED ON PERSISTENCE AND A BLEND OF
THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
120000Z3 IS 28 FEET. NEXT WARNINGS AT 121500Z9 AND 130300Z7.//
