REMARKS:
032100Z6 POSITION NEAR 15.4S0 81.5E4.
TROPICAL CYCLONE (TC) 16S HAS TRACKED WEST-SOUTHWEST AT 10 KTS IN
THE PAST 6 HOURS AND IS APPROXIMATELY 730 NM SOUTHEAST OF
DIEGO GARCIA ISLAND. THE WARNING POSITION IS BASED UPON ANIMATED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON
CURRENT INTENSITY ESTIMATES OF 35 KNOTS AND SYNOPTIC DATA. ANIMATED
SATELLITE IMAGERY REVEALS A COMPACT LOW-LEVEL CIRCULATION CENTER
(LLCC) AND DEEP CONVECTION OVERHEAD. TC 16S IS EXPECTED TO TRACK IN
A WEST-SOUTHWESTERLY DIRECTION TOWARD A WEAKNESS IN THE SUBTROPICAL
RIDGE. TC 16S IS EXPECTED TO INTENSIFY SLIGHTLY DURING THE FIRST 48
HOUR PERIOD THEN MAINTAIN INTENSITY THEREAFTER AS THE SYSTEM
APPROACHES A HIGHER VERTICAL WIND SHEAR ENVIRONMENT TOWARD THE END
OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031800Z2
IS 12 FEET. NEXT WARNINGS AT 040900Z3 AND 042100Z7. REFER TO
TROPICAL CYCLONE 17S (WALTER) WARNINGS (WTXS32 PGTW) FOR TWELVE-
HOURLY UPDATES.//
