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 (REMNANTS 27S) PREVIOUSLY LOCATED\r\nNEAR 25.0S 88.4E IS NOW LOCATED NEAR 24.8S 88.6E, APPROXIMATELY 888 NM \r\nSOUTH-SOUTHWEST OF THE COCOS ISLANDS. THE SYSTEM IS CURRENTLY CLASSIFIED \r\nAS A SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL \r\nAND MID-LATITUDE CYCLONE FEATURES. ENHANCED INFRARED SATELLITE IMAGERY \r\n(EIR) DEPICTS AN EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH NO \r\nAPPARENT DEEP CONVECTION SUPPORTED BY A 011221Z SSMIS F16 91H MICROWAVE \r\nIMAGE. ENVIRONMENTAL ANALYSIS REVEALS AN UNFAVORABLE ENVIRONMENT FOR \r\nDEVELOPMENT WITH HIGH VERTICAL WIND SHEAR (VWS), WEAK UPPER-LEVEL \r\nOUTFLOW AND COLD SEA SURFACE TEMPERATURES OF 24-25 C. BOTH \r\nDETERMINISTIC AND ENSEMBLE MODELS GENERALLY AGREE THAT THE SYSTEM WILL \r\nWEAKEN OVER THE NEXT 48 HOURS, ALTHOUGH THE GEFS MODEL SUGGESTS THAT \r\nTHE SYSTEM WILL MAINTAIN ITS INTENSITY DURING THIS PERIOD. FOR HAZARDS \r\nAND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS \r\nAND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 38 TO 43 KNOTS. \r\nMINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE \r\nPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN \r\nTHE NEXT 24 HOURS IS LOW.\r\n      (2) NO OTHER SUBTROPICAL SYSTEMS.//"
