WTPS21 PGTW 20030205 07:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE FORMATION ALERT 050651Z FEB 03// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN A 170 NM RADIUS OF 12.4S7 163.6W6 WITHIN THE NEXT 06 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 25 TO 30 KNOTS. METSAT IMAGERY AT 050630Z4 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 10.8S9 162.9W8. THE SYSTEM IS QUASI-STATIONARY AT 00 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.0S1 162.4W3 IS NOW LOCATED NEAR 10.8S9 163.0W0, APPROXIMATELY 495 NM EAST-NORTHEAST OF PAGO PAGO. ANIMATED MULTISPECTRAL AND ENHANCED INFRARED SATELLITE IMAGERY INDICATES THAT THE DEEP CONVECTION CONTINUES TO ORGANIZE OVER AN AREA OF BROAD TROUGHING AT THE SURFACE. UPPER LEVEL ANALYSIS INDICATES FAVORABLE OUTFLOW ALOFT ASSOCIATED WITH A POINT SOURCE AND MINIMAL VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 22 TO 28 KNOTS AND MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1002 MB. BASED ON IMPROVED ORGANIZATION AND PERSISTANCE, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS NOW UPGRADED TO GOOD 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 060700Z3.// ========================================================================= WTPS32 PGTW 20030205 21:00z 1.
