MEDIUM!!!
AN AREA OF CONVECTION HAS PERSISTED NEAR 5.8N 143.8E,
APPROXIMATELY 450 NM SOUTH OF GUAM. ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS A DISORGANIZED LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH FLARING DEEP CONVECTION. A 162334Z ASCAT IMAGE, HOWEVER,
DEPICTS A SYMMETRIC CIRCULATION WITH 15 TO 20 KNOT WINDS. UPPER-
LEVEL ANALYSIS INDICATES THAT THE DISTURBANCE IS LOCATED JUST
EQUATORWARD OF THE RIDGE AXIS WITH WEAK VERTICAL WIND SHEAR AND FAIR
OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS MEDIUM.
不知道今日餘下時間有沒有HIGH???
