"ABIO10 PGTW 182000\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN \r\nREISSUED/182000Z-191800ZFEB2026//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 97S) PREVIOUSLY LOCATED NEAR \r\n11.8S 74.8E IS NOW LOCATED NEAR 12.5S 76.1E, APPROXIMATELY 375 NM \r\nSOUTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE \r\nIMAGERY (EIR) DEPICTS A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER \r\n(LLCC) WITH PERSISTENT DEEP CONVECTION IN THE SOUTHWEST QUADRANT. A \r\n181535Z ASCAT-B PASS REVEALS 25-30 KNOT WINDS CONSOLIDATING IN THE \r\nNORTHERN AND SOUTHERN PERIPHERIES. ENVIRONMENTAL ANALYSIS FOR THE AREA \r\nINDICATES A MARGINALLY FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH \r\nMODERATE VERTICAL WIND SHEAR (15-20 KNOTS), WARM SEA SURFACE \r\nTEMPERATURES (28-29 C), AND MODERATE POLEWARD OUTFLOW ALOFT. GLOBAL \r\nMODELS ARE IN GOOD AGREEMENT ON A STEADY DEVELOPMENT AND A SOUTH-\r\nSOUTHWESTWARD TRACK OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE \r\nWINDS ARE ESTIMATED AT 27 TO 32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS \r\nESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY:\r\n      (1) THE AREA OF CONVECTION (TC 21S) PREVIOUSLY LOCATED NEAR \r\n31.5S 42.1E IS NOW LOCATED NEAR 36.8S 42.3E, APPROXIMATELY 876 NM \r\nSOUTH OF EUROPA ISLAND.THE SYSTEM IS CURRENTLY CLASSIFIED AS A \r\nSUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL \r\nAND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED INFRARED SATELLITE \r\nIMAGERY (EIR) DEPICTS A FULLY EXPOSED LOW-LEVEL CIRCULATION (LLCC) \r\nWITH FLARING CONVECTION LOSING INTENSITY IN THE SOUTHERN QUADRANT. \r\nENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES UNFAVORABLE CONDITIONS \r\nFOR TRANSITION TO A FULLY TROPICAL SYSTEM WITH LOW TO MODERATE \r\nVERTICAL WIND SHEAR (15-20 KNOTS), COOL SEA SURFACE TEMPERATURES (21-\r\n22 DEGREES CELSIUS) AND WEAK POLEWARD OUTFLOW ALOFT. GLOBAL MODELS ARE \r\nIN GOOD AGREEMENT THAT 21S WILL CONTINUE TO WEAKEN AS IT MOVES FARTHER \r\nSOUTH OVER PROGRESSIVELY COLDER WATERS. FOR HAZARDS AND WARNINGS, \r\nREFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS \r\nPRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM \r\nSUSTAINED SURFACE WINDS ARE ESTIMATED AT 37 TO 43 KNOTS. MINIMUM SEA \r\nLEVEL PRESSURE IS ESTIMATED TO BE NEAR 991 MB. THE POTENTIAL FOR THE \r\nDEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS \r\nIS LOW.\r\n      (2) NO OTHER SUBTROPICAL SYSTEMS.\r\n3. JUSTIFICATION FOR REISSUE: DUE TO FINAL WARNING EXPIRING AND 21S \r\nBECOMING FULLY SUBTROPICAL LISTED IN PARA 2.C.(1).//"
