JTWC15Z加報評級
終於評級Low
AN AREA OF CONVECTION HAS PERSISTED NEAR 7.8N 136.2E,
APPROXIMATELY 100 NM EAST-NORTHEAST OF KOROR, PALAU. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS FLARING CONVECTION
ASSOCIATED WITH A FAIRLY DEFINED MID-LEVEL CIRCULATION. HOWEVER, A
181205Z ASCAT PASS SHOWS NO IDENTIFIABLE LOW LEVEL CIRCULATION.
SURFACE OBSERVATIONS FROM KOROR DEPICT WEAK AND VARIABLE WINDS,
SUPPORTING THE ASCAT DATA. A 181205Z AMSU-B MICROWAVE IMAGE
ADDITIONALLY DEPICTS SOME DRY AIR WRAPPING IN FROM THE SOUTH WHICH
CAN ALSO BE SEEN IN THE TOTAL PRCIPITABLE WATER LOOP. UPPER LEVEL
ANALYSIS REVEALS THE AREA IS EQUATORWARD OF THE RIDGE AXIS WITH FAIR
OUTFLOW AND LOW TO MODERATE (10 TO 15 KNOTS) VERTICAL WIND SHEAR.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
對流又開始消消長長
現在轉鬆散-.-
