SOUTHERN HEMISPHERE/SOUTH INDIAN OCEAN: INVEST 96S. TROPICAL CYCLONE FORMATION ALERT ISSUED AT 24/2130UTC.

THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED  NEAR 9.8S 89.8E IS NOW LOCATED NEAR 10.4S 89.8E, APPROXIMATELY 785  KM WEST-NORTHWEST OF COCOS ISLANDS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY AND A 241910Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT  CONSOLIDATING CONVECTION OVER AN OBSCURED LOW LEVEL CIRCULATION  (LLC). A BULLSEYE 241603Z METOP-B IMAGE REVEALS ASYMMETRIC INCREASED  WINDS OF 30KTS WITHIN THE NORTHERN SEMI-CIRCLE OF 96S. HOWEVER, 96S  REMAINS EMBEDDED WITHIN THE SOUTH INDIAN CONVERGENCE ZONE WITH  TROUGH LIKE FEATURES. UPPER LEVEL ANALYSIS INDICATES THERE IS A  MARGINAL ENVIRONMENT WITH MODERATE TO HIGH (20-30 KNOTS) VERTICAL  WIND SHEAR (VWS) TO THE NORTH OF 96S AND MODERATE TO WEAK (10-15  KNOTS) VWS TO THE SOUTH. THE STRONG VWS IS BEING OFFSET BY FAIR  RADIAL OUTFLOW, DIVERGENCE ALOFT AND WARM (29-30C) SEA SURFACE  TEMPERATURES. GLOBAL MODELS GENERALLY AGREE THAT INVEST 96S WILL  CONSOLIDATE AND STRENGTHEN AS IT PROPAGATES SOUTH-SOUTHWESTWARD.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.  MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE  POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE  WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH.

WESTERN NORTH PACIFIC/PHILIPPINE SEA: INVEST 91W. ADVISORY(ABPW) ISSUED AT 25/06UTC.

THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED  NEAR 8.4N 129.6E IS NOW LOCATED NEAR 8.2N 124.2E, APPROXIMATELY 730  KM EAST-SOUTHEAST OF PUERTO PRINCESA, PHILIPPINES. ANIMATED ENHANCED  MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 250450Z GMI 89GHZ  MICROWAVE IMAGE DEPICTS DISORGANIZED CONVECTION WRAPPING INTO A  PARTIALLY EXPOSED LOW LEVEL CIRCULATION (LLC). ENVIRONMENTAL  ANALYSIS INDICATES OVERALL FAVORABLE CONDITIONS DEFINED BY LOW TO  MODERATE (15-20 KNOTS) VERTICAL WIND SHEAR, AND FAIR POLEWARD  OUTFLOW. ECMWF AND GFS ARE IN GENERAL AGREEMENT ON THE WESTWARD  TRACK OF INVEST 91W AND DESPITE THE OVERALL FAVORABLE ENVIRONMENT,  LIMITED TIME OVER WATER AND MAKING LANDFALL OVER MINDANAO INDICATES  THE SYSTEM IS NOT EXPECTED TO REACH WARNING CRITERIA IN THE NEXT 48  HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23  KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.  THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE  WITHIN THE NEXT 24 HOURS REMAINS LOW.
