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.
