REMARKS:
042100Z7 POSITION NEAR 13.3S7 57.6E8.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY 415 NM
NORTH OF MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
041730Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 77 and
90 KNOTS. THE SYSTEM IS EXPECTED TO CONTINUE TRACKING SOUTH-
WESTWARD FOR THE FORECAST PERIOD ALONG THE NORTHWESTERN
PERIPHERY OF THE MID-LEVEL STEERING RIDGE LOCATED TO THE SOUTH.
ALTHOUGH DRY AIR ENTRAINMENT HAS SIGNIFICANTLY REDUCED CONVECTION,
THE INTENSITY WILL CONTINUE TO INCREASE BEYOND CLIMATOLOGICAL
RATES THROUGH THE ENTIRE FORECAST PERIOD DUE TO EXCELLENT POLAR,
CROSS EQUATORIAL, AND WESTWARD OUTFLOW IN A FAVORABLE UPPER LEVEL
ENVIRONMENT. AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, EGRR,
GFDN, AND NCEP GFS ARE IN GOOD AGREEMENT WITH THIS SCENARIO.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z3 IS 24 FEET.
NEXT WARNINGS AT 050900Z4 AND 052100Z8.//
