過了一夜就評級為LOW了
這支昨天在JMA的天氣圖中似乎就有預測它的出現
AN AREA OF CONVECTION HAS PERSISTED NEAR 3.4N 132.9E,
APPROXIMATELY 260 NM SOUTH-SOUTHWEST OF PALAU. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY SHOWS A SERIES OF EASTERLY WAVES TRACKING
INTO A REGION OF TIGHT TROUGHING. AS THE LEADING WAVE APPROACHES THE
EASTERN EXTENT OF THE MONSOON TROUGH, INCREASED VORTICITY AND
CONVECTION HAS BEEN OBSERVED. TOTAL PRECIPITABLE WATER IMAGERY
SUPPORTS AN INCREASE IN VORTICITY. UPPER LEVEL ANALYSIS INDICATES
THE LLCC IS WITHIN A DIFFLUENT REGION OF A SUBTROPICAL RIDGE
CREATING MODERATE VWS (10-20 KNOTS). 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.
