JTWC評級Low
(1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 6.4N
140.7E, APPROXIMATELY 285 NM SOUTHEAST OF YAP. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 202057Z SSMIS 91GHZ
MICROWAVE IMAGE DEPICT FLARING CONVECTION OVER A BROAD AREA OF
CIRCULATION. ENVIRONMENTAL ANALYSIS DEPICTS GENERALLY FAVORABLE
CONDITIONS FOR DEVELOPMENT WITH ROBUST EQUATORWARD OUTFLOW, LOW (5-
10 KTS) VERTICAL WIND SHEAR (VWS), AND WARM (30-31C) SEA SURFACE
TEMPERATURES. GLOBAL MODELS INDICATE THAT 98W WILL TRACK WEST-
NORTHWESTWARD, AND ARE SPLIT ON DEVELOPMENT, WITH THE GFS SHOWING
SOME CONSOLIDATION AND DEEPENING. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAvL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TOLOW.
