AN AREA OF CONVECTION HAS PERSISTED NEAR 9.5N 72.0E, APPROXIMATELY 575 NM SOUTH OF MUMBAI, INDIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A WELL-DEFINED BUT EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION SHEARED WEST OF THE CENTER. A 041328Z SSMIS IMAGE INDICATES WEAK, FORMATIVE CONVECTIVE BANDING WRAPPING BROADLY INTO THE LLCC. A 040505Z ASCAT IMAGE SHOWED A DEFINED LLCC WITH 15 TO 25 KNOT WINDS. UPPER-LEVEL ANALYSIS INDICATES A MARGINAL ENVIRONMENT WITH MODERATE TO STRONG, EASTERLY VERTICAL WIND SHEAR (20-30 KNOTS). MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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.
