SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN180 NM EITHER
SIDE OF A LINE FROM 8.8N 115.5E TO 7.3N 107.7E 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 IMAGE
RY AT 301900Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 8.4N 114.9E.
THE SYSTEM IS MOVING NORTHWARD AT 04 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 7.1N
113.7E, IS NOW LOCATED NEAR 8.4N 114.9E, APPROXIMATELY 215 NM NORTH OF BRUNEI.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 301417Z MHS 89GHZ MICROWAVE
IMAGE DEPICT AN ELONGATED CIRCULATION WITH FLARING CONVECTION TO THE NORTHWEST
AND SOUTHEAST OF THE CENTER. A 301310Z ASCAT PASS CONFIRMS THE ELONGATED SHAPE
OF THE CIRCULATION AND SHOWS PRIMARILY 10-15 KNOT WINDS NEAR THE CENTER AND
20-25 KNOT WINDS ALONG THE PERIPHERY BUT NOT YET WRAPPING IN. THE DISTURBANCE
IS CURRENTLY LOCATED IN AN AREA OF GOOD POLEWARD DIVERGENCE, HIGH VERTICAL WIND
SHEAR (25-30 KNOTS), AND WARM SEA SURFACE TEMPERATURES (28-30 CELSIUS). GLOBAL
MODELS ARE IN AGREEMENT THAT THE DISTURBANCE WILL BEGIN TRACKING WEST AFTER A
SHORT PERIOD OF QUASI-STATIONARY MOVEMENT AND WILL CONSOLIDATE AS IT PASSES
SOUTH OF VIETNAM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIA
L FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOUR
S IS HIGH.
