WTXS21 PGTW 20061129 00:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE FORMATION ALERT 282351ZNOV06// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 080 NM EITHER SIDE OF A LINE FROM 9.9S 43.6E TO 11.3S 40.9E WITH- IN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY IS- SUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT 281800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 10.2S 42.9E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 11 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.8S 44.4E, IS NOW LOCATED NEAR 10.2S 42.9E, APPROXIMATELY 580 NM NORTH-NORTHWEST OF ANTANANARIVO, MADAGASCAR. ANIMATED INFRARED SATELLITE IMAGERY REVEALS INCREASED CONVECTION OVER THE LOW-LEVEL CIRCULATION CENTER AND BANDING WRAPPING INTO THE CENTER ON THE NORTHERN AND SOUTHERN PERIPHERIES OF THE DISTURBANCE. UPPER LEVEL ANALYSIS INDICATES AN ANTICYCLONE ALOFT OF THE DISTURBANCE CONTRIBUTING TO GOOD POLEWARD OUTFLOW AND LOW VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. DUE THE DEVELOPMENT OF CONVECTION AROUND THE LOW-LEVEL CIRCULATION CENTER, 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 300000Z.// ========================================================================= WTXS31 PGTW 20061129 15:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE WARNING// AMPN/TROPICAL CYCLONE FORMATION ALERT// REF/A/NAVPACMETOCCEN PEARL HARBOR HI/212351Z NOV 06// 1.

TROPICAL CYCLONE (TC) 03S, LOCATED APPROXIMATELY 570 NM NORTH- NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED MULTISPEC- TRAL AND MICROWAVE SATELLITE IMAGERY SHOW DEEP CONVECTIVE BANDING WRAPPING INTO AN INCREASINGLY WELL-DEFINED CIRCULATION CENTER. THIS SYSTEM IS EXPECTED TO TRACK GENERALLY SOUTHWARD OVER THE NEXT 48 ALONG THE WESTERN PERIPHERY OF A STEERING RIDGE ANCHORED NORTHEAST OF MADAGASCAR. LOW VERTICAL WIND SHEAR AND GOOD POLEWARD AND EQUATORWARD OUTFLOW ARE EXPECTED TO FACILITATE INTENSIFICATION AT A CLIMATOLOGICAL RATE THROUGHOUT THE FORECAST PERIOD. INTENSITY OF THIS SYSTEM WILL DEPEND STRONGLY UPON TRACK. IF THE STEERING RIDGE BUILDS FURTHER WESTWARD THAN CURRENTLY FORECAST, THE LOW LEVEL CIRCULATION ASSOCIATED WITH THIS SYSTEM COULD MOVE ASHORE AND DISSIPATE. THIS POSSIBILITY IS PRESENTED AS AN ALTERNATE FORECAST SCENARIO.

ALTHOUGH THE LOW-LEVEL CIRCULATION ASSOCIATED WITH TC 03S REMAINS WELL-DEFINED, THE DEEP CONVECTION ASSOCIATED WITH TC 03S HAS DISSIPATED DUE TO MODERATE TO HIGH VERTICAL WIND SHEAR. THE LOW-LEVEL CIRCULATION WILL CONTINUE TO TRACK TO THE SOUTH-SOUTHEAST, BUT DUE TO CONTINUED UNFAVORABLE CONDITIONS REGENERATION OF TC 03S IS UNLIKELY. 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 020000Z IS 12 FEET.//
