JTWC0130Z評級Low
(2) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 5.7N
157.9E, APPROXIMATELY 373 NM EAST-SOUTHEAST OF CHUUK. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A PARTIALLY EXPOSED LOW
LEVEL CIRCULATION WITH FLARING CONVECTION OVER THE EASTERN
SEMICIRCLE. A 262110Z ASCAT-A PASS REVEALS STRONGER WINDS (20-25KTS)
NORTH OF THE CONSOLIDATING CIRCULATION WITH WEAKER WINDS ELSEWHERE.
UPPER LEVEL ANALYSIS INDICATES LOW (10-15KTS) VERTICAL WIND SHEAR
AND A DEVELOPING EQUATORWARD OUTFLOW CHANNEL. SEA SURFACE
TEMPERATURES ARE FAVORABLE FOR DEVELOPMENT AT 29-30 DEGREES CELSIUS.
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 90W WILL CONTINUE TO
TRACK WESTWARD AS IT DEVELOPS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
