REMARKS:
072100Z0 POSITION NEAR 16.5S2 046.3E3.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
170 NM NORTH OF ANTANANARIVO, MADAGASCAR HAS TRACKED
WEST-SOUTHWESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 071730Z8 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 77 AND 90 KNOTS. RECENT
SATELLITE IMAGERY INDICATES WEAKENING OF TC 16S AS IT CONTINUES
TO INTERACT WITH LAND. TC 16S IS EXPECTED TO CONTINUE TO TRACK
SOUTHWESTWARD THROUGH TAU 12 ALONG THE NORTHWESTERN PERIPHERY
OF THE MID LEVEL STEERING RIDGE LOCATED TO THE SOUTHEAST. AN
APPROACHING MID-LATITUDE TROUGH HAS WEAKENED THE RIDGE TO THE
SOUTH OF TC 16S. TC 16S IS FORECAST TO TRANSITION TO A MORE
POLEWARD TRACK FOR THE REMAINDER OF THE FORECAST PERIOD. THE
INTENSITY OF TC 16S IS EXPECTED TO CONTINUE TO SLOWLY WEAKEN
DUE TO INTERACTION WITH LAND. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, EGRR, GFDN, AFWA MM5 AND NCEP GFS ARE
IN FAIR AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF
THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 071800Z6 IS 24 FEET. NEXT WARNINGS AT 080900Z7 AND
082100Z1.//
