JTWC評級Low
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST AREA 91W) HAS PERSISTED NEAR
11.9N 157.6E, APPROXIMATELY 285 NM NORTH OF POHNPEI. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD AREA OF MONSOON
TROUGHING WITH EMBEDDED LOOSELY ORGANIZED FLARING CONVECTION. A
102328Z ASCAT PASS SHOWS A LOW LEVEL CIRCULATION CENTER (LLCC)
WITHIN THE TROUGHING, AND MODELS ARE INDICATING A GRADUAL
CONSOLIDATION OF THIS AREA OVER THE NEXT ONE TO TWO DAYS. UPPER
LEVEL CONDITIONS ARE CURRENTLY MARGINAL WITH MOSTLY STRAIGHT LINE
FLOW OVERHEAD AND A SHARP GRADIENT OF VERTICAL WIND SHEAR INCREASING
TO THE SOUTH OF THE LLCC. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE IN THE NEXT 24 HOURS IS LOW.
JMA預測明天晚上之前升熱帶低壓。
