JTWC : Low ,對流雜亂,需要長時間整合,估計24小時內進入南海
(1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR
14.5N 123.6E, APPROXIMATELY 155 NM EAST OF MANILA, PHILIPPINES.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 290055Z METOP-B 89
GHZ MICROWAVE IMAGE DEPICT A BROAD LOW LEVEL CIRCULATION WITH
DISORGANIZED FLARING CONVECTION. ENVIRONMENTAL ANALYSIS REVEALS GOOD
POLEWARD OUTFLOW ALOFT, LOW VERTICAL WIND SHEAR, AND WARM (29-31C)
SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GENERAL AGREEMENT
THAT INVEST 91W WILL CONTINUE TO TRACK WESTWARD ACROSS LUZON AND
INTO THE SCS WHERE IT WILL GRADUALLY INTENSIFY. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
