WTPS21 PGTW 20061021 22:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE FORMATION ALERT 212151Z OCT 06// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 120 NM EITHER SIDE OF A LINE FROM 10.9S 167.9E TO 13.5S 166.2E WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 30 TO 35 KNOTS. METSAT IM- AGERY AT 211800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 11.0S 167.9E. THE SYSTEM IS MOVING SOUTHWARD AT 06 KNOTS. 2. REMARKS: AN AREA OF CONVECTION NEAR 11.0S 167.9E, APPROXIMATELY 665 NM NORTHWEST OF NADI, FIJI, HAS PERSISTED OVER THE PAST 12 HOURS. RECENT ANIMATED INFRARED SATELLITE IMAGERY SHOWS FLARING CONVECTION WRAPPING INTO A WELL-DEFINED LOW LEVEL CIRCULATION CENTER EVIDENT IN A 211930Z SSMI MICROWAVE IMAGE. UPPER LEVEL ANALYSIS INDICATES LOW VERTICAL WIND SHEAR AND EXCELLENT OUTFLOW ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. BASED ON IMPROVED LOWER LEVEL ORGANIZATION, INCREASING CONVECTION, AND FAVORABLE UPPER LEVEL CONDITIONS, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 222200Z.// ========================================================================= WTPS31 PGTW 20061022 03:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE WARNING// AMPN/TROPICAL CYCLONE FORMATION ALERT// REF/A/NAVPACMETOCCEN PEARL HARBOR HI/212151Z OCT 06// 1.

TC 01P CONTINUES TO TRACK BETWEEN THE SUBTROPICAL RIDGE TO ITS EAST AND A MIDLATITUDE TROUGH OVER NEW ZEALAND. TC 01P HAS WEAKENED AS IT HAS ENCOUNTERED A REGION OF MOD- ERATE TO HIGH VERTICAL WIND SHEAR ASSOCIATED WITH THE MIDLATITUDE WESTERLY FLOW. A 241848Z SSMI PASS INDICATES THAT THE DEEP CONVECT- ION ASSOCIATED WITH TC 01P IS BEGINNING TO DECOUPLE FROM THE LOW LEVEL CIRCULATION CENTER. THE AVAILABLE DYNAMIC AIDS CONTINUE TO HAVE A POOR HANDLE ON THE SYSTEM, REFLECTING A SHARP WESTWARD TURN INCONSISTENT WITH THE CURRENT SYNOPTIC ENVIRONMENT. THEREFORE, THIS FORECAST IS WEIGHTED TOWARD THE WBAR (THE BEST PERFORMING MODEL SO FAR) AND THE BETA ADVECTION MODELS WHICH INDICATE A SOUTHEASTWARD TO SOUTHWARD TRACK.

THE CURRENT BEST TRACK POSITION HAS BEEN RELOCATED BASED ON RECENT ANIMATED MULTISPECTRAL AND MIC- ROWAVE SATELLITE IMAGERY, WHICH REVEAL THAT HIGH VERTICAL WIND SHEAR HAS DECOUPLED THE CONVECTION ASSOCIATED WITH THIS SYSTEM FROM THE LOW LEVEL CIRCULATION CENTER (LLCC). THIS SATELLITE IMAGERY AND A 251838Z QUIKSCAT PASS INDICATE THAT THE NOW FULLY EXPOSED LLCC IS TRACKING NORTHWESTWARD UNDER THE INFLUENCE OF STRONG LOWER LEVEL SOUTHEASTERLY FLOW. THE FOREMENTIONED VERTICAL WIND SHEAR HAS CONTRIBUTED TO THE RAPID WEAKENING OF THIS SYSTEM AND FULL DISSIP- ATION IS EXPECTED BY TAU 12. THEREFORE, THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 260000Z IS 14 FEET.//
