JTWC 06Z評級LOW
(2) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR
9.5N 126.2E, APPROXIMATELY 430 NM SOUTHEAST OF MANILA,
PHILIPPINES . ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
FULLY EXPOSED AND POORLY-ORGANIZED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH FLARING CONVECTION ALONG THE NORTHERN PERIPHERY. A
RECENT 310033Z METOP-A ASCAT PASS SHOWS 5-10 KNOT WINDS IN THE
CENTER, STRONGER WINDS TO NORTH ASSOCIATED WITH THE BANDING
CONVECTION, AND OVERALL ELONGATED FLOW. UPPER LEVEL ANALYSIS
REVEALS MODERATE VERTICAL WIND SHEAR (15-20KTS), EQUATORWARD
OUTFLOW, AND FAVORABLE SEA SURFACE TEMPERATURES (29-31C). GLOBAL
MODELS SHOW THE DISTURBANCE MOVING WESTWARD AND LATER DEVELOPING IN
THE SOUTH CHINA SEA BEYOND TAU 48. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE DEVELOPMENT OF
A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
