WTPS21 PGTW 961220 13:00z SUBJ/TROPICAL CYCLONE FORMATION ALERT 201251Z DEC 96// RMKS/ 1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA 2. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY AND AMEMBASSY HONIARA SOLOMON ISLANDS 3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 090 NM EITHER SIDE OF A LINE FROM 5.7S2 166.0E3 TO 9.6S5 163.1E1 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 25 TO 30 KNOTS. METSAT IMAGERY AT 201130Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 6.5S1 165.2E4. THE SYSTEM IS MOVING SOUTHWESTWARD AT 08 KNOTS. 4. REMARKS: A TROPICAL DISTURBANCE NORTHEAST OF THE SOLOMON ISLANDS CONTINUES TO BECOME BETTER ORGANIZED AS SHOWN BY BOTH ANIMATED VISIBLE AND INFRARED SATELLITE IMAGERY DURING THE PAST 12 HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS AN UPPER LEVEL ANTICYCLONE AS WELL AS WEAK UPPER- LEVEL WIND SHEAR ARE PRESENT OVER THIS SYSTEM. SURFACE SYNOPTIC REPORTS SHOW A LARGE REGION OF INFLOW FROM THE EQUATOR IS PRESENT WHICH IS HELPING TO ENHANCE DEVELOPMENT OF THIS SYSTEM. MINIMUM CENTRAL PRESSURE IS ESTIMATED TO BE 1002 MB.
