(1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED
NEAR 12.5N 110.7E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.

JTWC1530Z評級Low,但對於環流龐大且鬆散的91W來說要在登陸越南前成旋時間已經有限
(1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR
12.3N 111.6E, APPROXIMATELY 295 NM SOUTHEAST OF DANANG, VIETNAM.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 060941Z SSMIS
91GHZ IMAGE REVEAL A BROAD LOW LEVEL CIRCULATION WITH WEAK FORMATIVE
BANDING IN THE NORTHERN SEMICIRCLE. INVEST 91W IS CURRENTLY IN A
MARGINALLY FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH BROAD UPPER
LEVEL DIFFLUENCE, LOW (<15KTS) VERTICAL WIND SHEAR, AND WARM (29-
30C) SEA SURFACE TEMPERATURES; HOWEVER, GLOBAL MODELS INDICATE
INVEST 91W WILL CONTINUE TO TRACK WESTWARD AND CONSOLIDATE SLIGHTLY
BEFORE MAKING LANDFALL IN 12-18 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
