"ABIO10 PGTW 021800\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN/021800Z-\r\n031800ZAPR2025//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE \r\n   C. SUBTROPICAL SYSTEM SUMMARY:\r\n      (1) THE AREA OF CONVECTION (SS 27S) PREVIOUSLY LOCATED NEAR 24.8S \r\n88.6E IS NOW LOCATED NEAR 25.1S 85.3E, APPROXIMATELY 892 NM NORTH-\r\nNORTHEAST OF THE COCOS ISLANDS. THE SYSTEM IS CURRENTLY CLASSIFIED AS A \r\nSUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND \r\nMID-LATITUDE CYCLONE FEATURES. ENHANCED INFRARED SATELLITE IMAGERY (EIR) \r\nDEPICTS AN EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH NO APPARENT \r\nDEEP CONVECTION. A 021617Z ASCAT METOP-B 25KM IMAGE REVEALS A BELT OF \r\nELEVATED WINDS (30-35 KNOTS) CONTINUING TO PERSIST ALONG THE SOUTHERN \r\nPERIPHERY OF THE SYSTEM. ENVIRONMENTAL ANALYSIS REVEALS AN UNFAVORABLE \r\nENVIRONMENT FOR DEVELOPMENT WITH HIGH VERTICAL WIND SHEAR (VWS), WEAK \r\nUPPER-LEVEL OUTFLOW AND COLD SEA SURFACE TEMPERATURES OF 24-25 C. BOTH \r\nDETERMINISTIC AND ENSEMBLE MODELS GENERALLY AGREE THAT THE SYSTEM WILL \r\nCONTINUE TO WEAKEN, ALTHOUGH THE GEFS MODEL SUGGESTS THAT THE SYSTEM \r\nWILL MAINTAIN ITS INTENSITY OVER THE NEXT 24 HOURS. FOR HAZARDS AND \r\nWARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND \r\nSEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM \r\nSEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR \r\nTHE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 \r\nHOURS REMAINS LOW.\r\n      (2) NO OTHER SUBTROPICAL SYSTEMS.//"
