REMARKS:
121500Z9 POSITION NEAR 27.0S9 55.0E0.
TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 320 NM
SOUTH OF LA REUNION ISLAND, HAS TRACKED SOUTH-SOUTHEASTWARD AT 17
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
121100Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 AND 102 KNOTS.
ANIMATED SATELLITE IMAGERY SHOWS THAT THE DEEP CONVECTION PRIMARILY
RESIDES TO THE POLEWARD SIDE OF THE SYSTEM AND THE EXTENT HAS
REMAINED CONSTANT OVER THE LAST 12 HOURS. TC 18S CONTINUES TO TRACK
SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A MID-LEVEL RIDGE TO
THE EAST. TC 18S SHOULD SLOWLY WEAKEN AS IT ENCOUNTERS COOLER SEA
SURFACE TEMPERATURES AND SHOULD BECOME EXTRATROPICAL BY THE END OF
THE FORECAST 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 121200Z6 IS FEET. NEXT
WARNINGS AT 130300Z7 AND 131500Z0.//
