WTXS21 PGTW 20021223 02:00z RMKS/ 1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS 2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 160 NM EITHER SIDE OF A LINE FROM 13.5S9 64.3E3 TO 9.3S2 68.4E8 WITHIN THE NEXT 06 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT IMAGERY AT 230000Z5 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 9.7S6 68.3E7. THE SYSTEM IS MOVING SOUTH-SOUTHWESTWARD AT 08 KNOTS. 3. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.0S9 70.2E9 IS NOW LOCATED NEAR 9.7S6 68.3E7, APPROXIMATELY 280 NM WEST-SOUTHWEST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY INDICATES INCREASED CONVECTION AND IMPROVED ORGANIZATION OVER THE PAST SIX HOURS. THE 200 MB ANALYSIS DEPICTS GOOD DIFFLUENCE ALOFT AND WEAK VERTICAL SHEAR ASSOCIATED WITH THE UPPER LEVEL RIDGE EXTENDING ALONG 11.0S2. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1007 MB. DUE TO THE INCREASED CONVECTION, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD. 4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 240200Z8.// ========================================================================= WTXS31 PGTW 20021223 15:00z 1.
