JTWC 評級Low
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 5.4N 146.0E,
APPROXIMATELY 160 NM SOUTHWEST OF POHNPEI. ANIMATED MULTISPECTRAL
IMAGERY DEPICTS AN INTENSIVE AREA OF DEEP CONVECTION ASSOCIATED WITH
AN ILL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 042021Z SSMIS
REVEALS FRAGMENTED CONVECTIVE BANDING BROADLY WRAPPING INTO THE
LLCC. UPPER-LEVEL ANALYSIS INDICATES THE DISTURBANCE IS LOCATED IN A
MARGINALLY-FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND
SHEAR AND GOOD DIFFLUENCE ALOFT. ADDITIONALLY, WARM SEA SURFACE
TEMPERATURES ARE CONDUCIVE FOR DEVELOPMENT. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
