TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED NEAR \r\n26.0S 37.2E IS NOW LOCATED NEAR 25.1S 39.2E, APPROXIMATELY 180 NM \r\nSOUTH-SOUTHWEST OF EUROPA ISLAND. ANIMATED MULTISPECTRAL SATELLITE \r\nIMAGERY (MSI) REVEALS A COMPACT LOW LEVEL CIRCULATION CENTER (LLCC) WITH \r\nFLARING CONVECTION OVER THE SOUTHERN SEMICIRCLE. ENVIRONMENTAL ANALYSIS \r\nDEPICTS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH STRONG POLEWARD AND \r\nEQUATORWARD UPPER-LEVEL OUTFLOW, LOW TO MODERATE VERTICAL WIND SHEAR (15 \r\nTO 20 KTS), AND WARM SEA SURFACE TEMPERATURES (27 TO 28 C). GLOBAL \r\nMODELS AGREE ON 98S TRACKING EASTWARD INTO SOUTHERN MADAGASCAR AS IT \r\nQUICKLY CONSOLIDATES OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE \r\nWINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS \r\nESTIMATED TO BE NEAR 999 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE \r\nREF B (WTXS21 PGTW 200730) FOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//"
