AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT (WTPN21 PGTW 301300)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
100 NM EITHER SIDE OF A LINE FROM 13.8N 120.2E TO 15.3N 116.3E
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 301800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 13.8N 120.1E. THE SYSTEM IS MOVING WESTWARD AT 11 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 
13.8N 121.2E IS NOW LOCATED NEAR 13.8N 120.1E, APPROXIMATELY 70 NM 
SOUTHWEST OF MANILA, PHILIPPINES. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY (EIR) DEPICTS DEEP CONVECTION CONSOLIDATING OVER THE LOW-LEVEL 
CIRCULATION CENTER (LLCC) WITH CURVED DEEP CONVECTIVE BANDING IN THE 
SOUTHERN PERIPHERY. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT ONCE IT MOVES OVER THE SOUTH CHINA 
SEA WITH WARM SEA SURFACE TEMPERATURES (30-31C), LOW VERTICAL WIND SHEAR 
(10-15KTS), AND GOOD EQUATORWARD OUTFLOW ALOFT. GLOBAL MODELS ARE IN 
GOOD AGREEMENT THAT 96W WILL RAPIDLY INTENSIFY OVER THE NEXT 24 HOURS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
