REMARKS:
290300Z4 POSITION NEAR 20.4S6 48.0E2.
TROPICAL CYCLONE (TC) 11S (FARI) MADE LANDFALL AT APPROXIMATELY
290000Z1, 30 NM SOUTH OF MAHANORO, MADAGASCAR. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 55
KNOTS. TC 11S HAS TRACKED WESTWARD AT 10 KNOTS OVER THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 282330Z8 ENHANCED INFRARED
SATELLITE IMAGERY. A MID-LEVEL RIDGE CURRENTLY LOCATED SOUTH OF THE
SYSTEM IS EXPECTED TO MOVE EASTWARD AND BE THE PRIMARY STEERING
INFLUENCE OVER THE FORECAST PERIOD. THE SYSTEM IS EXPECTED TO TRACK
WESTWARD OVER THE NEXT 12 HOURS UNDER THE INFLUENCE OF THE RIDGE.
AFTER 12 HOURS, TC 11S WILL TRACK WEST-SOUTHWESTWARD AND THEN
SOUTHWARD TOWARDS A WEAKNESS IN THE MID-LEVEL RIDGE AS THE RIDGE
PROGRESSES EASTWARD. THE SYSTEM IS EXPECTED TO WEAKEN WHILE TRACKING
OVER MADAGASCAR, HOWEVER DEVELOPMENT AFTER THE SYSTEM ENTERS THE
MOZAMBIQUE CHANNEL IS EXPECTED. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, UK MET GLOBAL, AND GFDN, ARE IN FAIR AGREEMENT
WITH THIS SCENARIO. OUR FORECAST IS BASED ON A BLEND OF ALL
AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290000Z1
IS 09 FEET. NEXT WARNINGS AT 291500Z7 AND 300300Z6.//
