1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 8.6N 115.8E TO 12.6N 112.2E
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 18 TO 23 KNOTS. METSAT
IMAGERY AT 010000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 8.9N 115.7E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 08
KNOTS.

WRAPPING INTO A CONSOLIDATED LLCC. VWS REMAINS LOW (10-15 KTS) AND
DIVERGENCE ALOFT HAS IMPROVED OVER THE LAST TWELVE HOURS.
SSTS REMAIN WARM (29-30C) IN THE SOUTH CHINA SEA AND WILL SUPPORT
FURTHER DEVELOPMENT. GLOBAL MODELS PREDICT 99W WILL ASSUME A
