評價降為Low......隨著越近陸地,發展起來的機會也越小了....而且圈圈那麼大,不知道是94w還是97w....
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.2N 112.4E, IS NOW LOCATED NEAR 18.9N 111.8E, APPROXIMATELY 240 NM SOUTH-SOUTHWEST OF HONG KONG. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL CIRCULATION CENTER (LLCC) WITH FLARING DEEP CONVECTION OVER THE WESTERN SEMI-CIRCLE. A 191355Z METOP-B 89 GHZ IMAGE DEPICTS WEAK DEEP CONVECTION WHILE HINTING AT LOW TO MID-LEVEL TURNING. A 191634Z SCATTEROMETRY PASS DOES NOT RESOLVE THE LLCC IDENTIFIED IN THE EIR, BUT DOES REVEAL 10 TO 15 KNOT SOUTHERLY AND SOUTHEASTERLY WINDS ACROSS THE NORTHERN SOUTH CHINA SEA. UPPER-LEVEL ANALYSIS SHOWS A MARGINAL ENVIRONMENT WITH WEAK DIFFLUENCE AND LOW TO MODERATE (10-20 KNOTS) VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 DOWNGRADED TO LOW.
