過了半天後
似乎93W形態轉差了
LLCC附近的對流比昨天減少

發展機會不大了.....

JTWC：DOWNGRADED TO LOW
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 19.2N
133.9E, IS NOW LOCATED NEAR 19.2N 133.0E, APPROXIMATELY 516 NM
SOUTHEAST OF OKINAWA, JAPAN. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS SCATTERED DEEP CONVECTION SHEARED TO THE WEST OF A
FULLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC). A 300041Z 89 GHZ
METOP-A MICROWAVE IMAGE REVEALS A DEFINED LLCC WITH DRY AIR WRAPPING
AROUND THE EASTERN SEMI-CIRCLE. UPPER LEVEL ANALYSIS INDICATES AN
ENVIRONMENT CHARACTERIZED BY MODERATE (15-25 KNOTS) VERTICAL WIND
SHEAR AND FAIR EQUATORWARD OUTFLOW. NUMERICAL MODELS ONLY INDICATE
DEVELOPMENT OF A WEAK CIRCULATION AT THIS TIME. 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 DOWNGRADED TO LOW.
