WTXS21 PGTW 20030304 21:30z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE FORMATION ALERT 042121ZMAR03// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN A 125 NM RADIUS OF 11.5S7 78.4E9 WITHIN THE NEXT 06 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF A NUMBERED TROPICAL CYCLONE WARNING AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 35 KNOTS. METSAT IMAGERY AT 041730Z5 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 11.5S7 78.4E9. THE SYSTEM IS QUASI-STATIONARY. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.6S8 78.5E0, IS NOW LOCATED NEAR 11.5S7 78.7E2, APPROXIMATELY 445 NM SOUTHEAST OF DIEGO GARCIA. ANIMATED INFRARED SATELLITE IMAGERY AND A 041307Z5 SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS INDICATES DEEP CONVECTION OVER A LOW LEVEL CIRCULATION CENTER (LLCC) HAS INCREASED IN ORGANIZATION OVER THE PAST 6 HOURS. DEEP CONVECTION IS LOCATED PRIMARILY WEST THROUGH SOUTHWEST OF THE LLCC. UPPER-LEVEL ANALYSIS INDICATES WEAK TO MODERATE VERTICAL WIND SHEAR AND FAVORABLE DIVERGENCE ALOFT OVER THE AREA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 35 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE OVER THE NEXT 24 HOURS IS UPGRADED TO GOOD. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 052130Z1. 4.

THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 25 KNOTS. RECENT ANIMATED SATELLITE IMAGERY SUGGESTS THAT THE INTENSITY IS SLIGHTLY HIGHER THAN DVORAK INTENSITY ESTIMATES GIVE DUE TO THE FULLY EXPOSED LOW LEVEL CIRCULATION CENTER. THE IMAGERY ALSO SUGGESTS THE SYSTEM IS DISSIPATING WHILE TRANSITIONING INTO AN EXTRATROPICAL SYSTEM, WITH THE REMAINING DEEP CONVECTION CONFINED TO THE SOUTHEAST QUADRANT. TC 23S IS FORECAST TO TRACK SOUTHWARD AND BE EXTRATROPICAL IN 12 HOURS. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN, NCEP AVIATION (AVN), AND UKMET OFFICE (EGRR) ARE IN GOOD AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS AND PERSISTENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151200Z9 IS 15 FEET.
