NORTH INDIAN OCEAN/BAY OF BENGAL: INVEST 92B. LOCATION AND MAXIMUM WINDS ESTIMATED AT 05/06UTC.ADVISORY(ABIO) ISSUED AT 05/0230UTC.CLICK ON THE IMAGERY BELOW TO GET IT ENLARGED.

AN AREA OF CONVECTION (INVEST 92B) HAS PERSISTED NEAR 8.5S  93.3E, APPROXIMATELY 30 KM NORTH-NORTHEAST OF BOMPAKA ISLAND.  ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY AND A 050027 SSMIS  91 GHZ IMAGE REVEAL DEEP BUT DISORGANIZED CONVECTION WRAPPING AROUND  A BROAD, WEAK LOW LEVEL CIRCULATION (LLC). ENVIRONMENTAL ANALYSIS  SHOWS THE INVEST IS IN A MARGINALLY FAVORABLE ENVIRONMENT FOR  DEVELOPMENT DEFINED BY FAIR EQUATORWARD OUTFLOW, MODERATE (15-20KT)  VERTICAL WIND SHEAR, AND VERY WARM (30-31C) SEA SURFACE  TEMPERATURES. GLOBAL MODEL GUIDANCE IS IN GOOD AGREEMENT THAT 92B  WILL TRACK NORTH-NORTHWESTWARD OVER THE NEXT 48-72 HOURS AND  GRADUALLY ORGANIZE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT  13 TO 18 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.

SOUTH INDIAN OCEAN: INVEST 90S. LOCATION AND MAXIMUM WINDS ESTIMATED AT 05/06UTC.ADVISORY(ABIO) ISSUED AT 05/0230UTC. CLICK ON THE IMAGERY BELOW TO GET IT ENLARGED.

THE AREA OF CONVECTION (INVEST 90S) PREVIOUSLY LOCATED  NEAR 6.5S 90.1E IS NOW LOCATED NEAR 7.0S 89.7E, APPROXIMATELY 1830 KM  EAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE  IMAGERY AND A 041417Z GMI 89GHZ IMAGE REVEAL FLARING DEEP CONVECTION  IN THE WESTERN SEMICIRCLE OF THE AREA WITH MOISTURE WRAPPING INTO A  FULLY EXPOSED AND VERY BROAD LOW LEVEL CIRCULATION. ENVIRONMENTAL  ANALYSIS SHOWS THE INVEST IS IN A MARGINALLY FAVORABLE AREA FOR  DEVELOPMENT WITH DECENT EQUATORWARD OUTFLOW AND VERY WARM SEA  SURFACE TEMPERATURES (30-31C) OFFSET BY HIGH (25-30KTS) VERTICAL  WIND SHEAR. GLOBAL MODEL GUIDANCE PREDICTS THE INVEST WILL TRACK  SOUTH-SOUTHWESTARDLY AND GRADUALLY CONSOLIDATE OVER THE NEXT 48-72  HOURS. 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 REMAINS LOW.
