JTWC00Z評級Low

(1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR 6.0N
168.0E, APPROXIMATELY 130 NM SOUTH-SOUTHWEST OF KWAJALEIN ISLAND.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS A CONSOLIDATING
AREA OF CONVECTION WITH FEEDER BANDS TO THE NORTH AND FLARING
CONVECTION WITH OVERSHOOTING TOPS JUST SOUTH OF A LOW LEVEL
CIRCULATION (LLC). A 071913Z SSMIS 91GHZ MICROWAVE PASS DEPICTS
FRAGMENTED BANDING WRAPPING INTO THE LLC WITH THE AFOREMENTIONED
CONVECTION TO THE SOUTH. INVEST 91W IS IN AN ENVIRONMENT FAVORABLE
FOR TROPICAL DEVELOPMENT WITH GOOD EQUATORWARD OUTFLOW ALOFT, LOW (5-
10KTS) VERTICAL WIND SHEAR (VWS) AND WARM (30-31C) SEA SURFACE
TEMPERATURES (SST). GLOBAL MODELS ARE NOT IN AGREEMENT WITH A
TROPICAL CYCLONE DEVELOPING FROM INVEST 91W, HOWEVER, JTWC WILL
CLOSELY MONITOR FOR POTENTIAL DEVELOPMENT DUE TO A FAVORABLE
APPEARANCE IN SATELLITE ANALYSIS. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

從風場看起來風力偏弱
結構也還有很多改善的空間
