降評為LOW!!
LOW是早上降的 剛剛又升回MEDIUM囉
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.2N
126.7E, IS NOW LOCATED NEAR 12.8N 126.3E, APPROXIMATELY 330 NM EAST-
SOUTHEAST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A SMALL, IMPROVED LOW LEVEL CIRCULATION CENTER (LLCC)
WITH INCREASED DEEP CENTRAL CONVECTION. A 011920Z SSMI MICROWAVE
IMAGE DEPICTS WEAK CONVECTIVE BANDING INTO THE LLCC. A SHIP
OBSERVATION 25 NM TO THE SOUTH-SOUTHEAST IS REPORTING 1004 MB WITH
05 KNOTS OF WIND. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS
LOCATED SOUTH OF THE RIDGE AXIS IN AN AREA OF MODERATE VERTICAL WIND
SHEAR AND WEAK DIVERGENCE ALOFT. THE VERTICAL WIND SHEAR HAS
RECENTLY WEAKENED AND ALLOWED CONVECTION TO BUILD OVER THE CENTER.
THE MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO
THE IMPROVED LLCC AND ASSOCIATED DEEP CONVECTION, BUT VICINITY TO
LAND, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM. |
