JTWC於03/1530Z提升評級至Medium。
(1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED
NEAR 12.3N 112.4E IS NOW LOCATED NEAR 12.4N 113.2E, APPROXIMATELY
360 NM SOUTHEAST OF DA NANG, VIETNAM. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND A 031332Z 89GHZ MHS MICROWAVE IMAGE DEPICT
FORMATIVE, SHALLOW BANDING IN THE SOUTHWEST QUADRANT OF A BROAD LOW
LEVEL CIRCULATION CENTER. A 031334Z ASCAT-A IMAGE FURTHER DEPICTS AN
ELONGATED CIRCULATION WITH 15-20 KNOT WINDS TO THE SOUTH AND WEST OF
THE CONSOLIDATING CENTER. UPPER LEVEL ANALYSIS INDICATES A
MARGINALLY FAVORABLE ENVIRONMENT WITH LOW TO MODERATE (10-20 KTS)
EASTERLY VERTICAL WIND SHEAR OFFSET BY STRONG DIFFLUENCE ALOFT. SEA
SURFACE TEMPERATURES ARE ALSO CONDUCIVE FOR DEVELOPMENT AT 29-30
CELSIUS. GLOBAL MODELS ARE IN AGREEMENT WITH NAVGEM, GFS, AND UKMET
SHOWING GRADUAL DEVELOPMENT AND QUASISTATIONARY MOVEMENT OVER THE
NEXT 24 HOURS AS THE NORTHEAST SURGE CONTINUES TO STRENGTHEN TO THE
WEST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
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 UPGRADED TO MEDIUM.
