REMARKS:
052100Z8 POSITION NEAR 14.5S0 054.8E7.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
370 NM NORTH OF MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION
IS BASED ON 051730Z6 ENHANCED INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 115 AND 127 KNOTS. RECENT MICROWAVE SATELLITE
IMAGERY DEPICTS A DISTINCT 15 NM DIAMETER EYE. TC 16S IS
EXPECTED TO CONTINUE TRACKING SOUTHWESTWARD OVER THE FORECAST
PERIOD AS IT TRACKS ALONG THE NORTHWESTERN PERIPHERY OF
THE MID-LEVEL STEERING RIDGE LOCATED TO THE SOUTHEAST OF
THE SYSTEM. IMPROVED DUEL OUTFLOW CHANNELS HAVE CONTRIBUTED
TO AN INTENSIFICATION RATE THAT HAS BEEN ABOVE CLIMATOLOGY
OVER THE PAST 24 HOURS. TC 16S IS FORECAST TO CONTINUE TO
INTENSIFY AT A SLIGHTLY LESS THAN CLIMATOLOGICAL RATE IN
A FAVORABLE UPPER LEVEL ENVIRONMENT OVER THE NEXT 12 TO
24 HOURS. BEYOND TAU 24 TC 16S IS FORECAST TO WEAKEN
SLOWLY DUE TO DECREASED POLEWARD OUTFLOW ALOFT AND
INTERACTION WITH LAND. THE AVAILABLE DYNAMIC AIDS CONSISTING
OF NOGAPS, EGRR, GFDN AND NCEP GFS ARE IN FAIR AGREEMENT
WITH THIS SCENARIO. THE DYNAMIC AIDS INDICATE MODERATE
DISAGREEMENT IN THE TIMING OF RECURVATURE OF THE SYSTEM
OVER MADAGASCAR, WITH NOGAPS AND NCEP GFS TURNING TC 16S
POLEWARD EARLIER THAN EGRR. THIS FORECAST IS BASED ON A
CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 051800Z4 IS 30 FEET. NEXT WARNINGS AT 060900Z5
AND 062100Z9.//
