REMARKS:
090300Z2 POSITION NEAR 11.9S1 52.5E2.
TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 205 NM
EAST OF CAPE D=AMBRE, MADAGASCAR, HAS TRACKED WEST-SOUTHWESTWARD AT
2 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
082330Z6 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 127 KNOTS.
ANIMATED INFRARED SATELLITE IMAGERY DEPICTS A 24 NM EYE. TC 18S IS
AT THE WESTERN EDGE OF A STRONG MID-LEVEL RIDGE AND HAS BEGUN TO
MAKE A POLEWARD TURN TOWARDS THE LONGWAVE TROUGH APPROACHING FROM
THE SOUTH-SOUTHWEST. THE SYSTEM=S TRACK SPEED HAS SLOWED BUT IS
FORECAST TO INCREASE ONCE THE POLEWARD TURN IS COMPLETE. TC 18S IS
FORECAST TO SLOWLY WEAKEN AS ITS WESTERN HALF INTERACTS WITH
MADAGASCAR=S EAST COAST AND THE LONGWAVE TROUGH TO THE SOUTH-
SOUTHWEST PASSES THE SYSTEM TO THE SOUTH, LIMITING THE OUTFLOW OF
THE SYSTEM. THE AVAILABLE DYNAMIC AIDS COMPRISE GFDN, AVN, NOGAPS
AND UK MET GLOBAL AND ARE IN GOOD AGREEMENT WITH THIS SCENARIO. THE
FORECAST TRACK IS BASED ON PERSISTENCE AND A BLEND OF THE AVAILABLE
DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090000Z9 IS 30
FEET. NEXT WARNINGS AT 091500Z5 AND 100300Z4.//
