WTPN21 PHNC 061430 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 93E)// REF/A/JOINT TYPHOON WRNCEN PEARL HARBOR HI/061321Z NOV 24// AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTPN21 PHNC 061330)// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 120 NM EITHER SIDE OF A LINE FROM 13.3N 106.8W TO 9.4N 100.9W 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 28 TO 33 KNOTS. METSAT IMAGERY AT 061200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 13.1N 106.4W. THE SYSTEM IS MOVING NORTH-NORTHEASTWARD AT 03 KNOTS. 2. REMARKS: AN AREA OF CONVECTION (INVEST 93E) IS LOCATED NEAR 13.1N 106.4W, APPROXIMATELY 426NM SOUTHEAST OF SOCORRO ISLAND, MEXICO. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) DEPICTS A CONSOLIDATING LOW- LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT DEEP CONVECTION. ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH LOW VERTICAL WIND SHEAR VALUES OF 10-15 KTS, GOOD UPPER- LEVEL POLEWARD OUTFLOW, AND WARM SEA SURFACE TEMPERATURES OF 29-30 DEGREES C. GLOBAL DETERMINISTIC MODELS ARE IN GOOD AGREEMENT THAT 93E WILL CONTINUE AS A WEAKLY DEFINED CIRCULATION AS IT TRACKS GENERALLY TO THE NORTHEAST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. THIS SUPERSEDES REF A. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 071430Z.// NNNN
