FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN A 180 NM RADIUS OF 15.4N 111.1E WITHIN THE NEXT 03 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 240430Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 15.4N 111.2E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 02 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.1N 111.8E, IS NOW LOCATED NEAR 15.4N 111.2E, APPROXIMATELY 200 NM SOUTH-SOUTHEAST OF HAINAN ISLAND, CHINA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN EXPOSED, WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION SHEARED 30 NM SOUTHWEST OF THE CENTER. A 232309Z SSMIS 37 GHZ IMAGE INDICATES WEAK CONVECTIVE BANDING NORTH WRAPPING INTO THE WEST QUADRANT. A 240229Z ASCAT IMAGE DEPICTS NUMEROUS UNFLAGGED 20-25 KNOT WINDS OVER THE WEST AND SOUTH QUADRANTS WITH SOME ISOLATED 30 KNOT WINDS. A BUOY OBSERVATION (9VDD2) 94 NM SOUTH-SOUTHEAST SHOWS WINDS AT 230/22 KNOTS. THE LLCC IS CURRENTLY LOCATED WITHIN A MARGINAL ENVIRONMENT WITH MODERATE EASTERLY VERTICAL WIND SHEAR (20 KNOTS) AND BROAD DIFFLUENCE ALOFT. THE SYSTEM IS FORECAST TO DRIFT NORTH INTO A SLIGHTLY MORE FAVORABLE ENVIRONMENT OVER THE NEXT 24-36 HOURS. IT WILL LIKELY CONTINUE TO STRUGGLE CONVECTIVELY, HOWEVER, THE LLCC HAS STRENGTHENED OVER THE PAST 12 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 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 250500Z.// NNNN -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.113.3.42
