REF B IS A TROPICAL CYCLONE \r\nFORMATION ALERT.//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR \r\n2.4S 74.5E IS NOW LOCATED NEAR 2.4S 75.2E, APPROXIMATELY 340 NM NORTH-\r\nNORTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY \r\nDEPICTS A PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION (LLC) WITH DEEP \r\nCONVECTION SHEARED OVER THE WESTERN SEMICIRCLE OF THE LLC. A 191310Z \r\nSSMIS 91 GHZ MICROWAVE IMAGE REVEALS CURVED DEEP CONVECTIVE BANDING OVER \r\nTHE WESTERN QUADRANT WITH SHALLOW BANDING EVIDENT OVER THE EASTERN \r\nQUADRANT. A 191601Z ASCAT-B IMAGE INDICATES AN ELONGATED CIRCULATION \r\nWITH 30-40 KNOT WINDS OVER THE WESTERN SEMICIRCLE, ASSOCIATED WITH THE \r\nPERSISTENT CONVECTION, AND 20-25 KNOT WINDS OVER THE EASTERN SEMICIRCLE. \r\nUPPER-LEVEL ANALYSIS REVEALS A MARGINAL ENVIRONMENT FOR DEVELOPMENT, \r\nWITH DIFFLUENT EASTERLY FLOW ALOFT, WARM SEA SURFACE TEMPERATURES (30C), \r\nAND STRONG VERTICAL WIND SHEAR (40-50KT). GLOBAL MODELS ARE IN GOOD \r\nAGREEMENT THAT 93S WILL GENERALLY TRACK EASTWARD OVER THE NEXT TWO DAYS \r\nWHILE WEAKENING STEADILY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED \r\nAT 30 TO 35 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR \r\n1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL \r\nCYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE REF B (WTXS21 PGTW \r\n191400) FOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS."
