THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.9S 52.1E, IS NOW LOCATED NEAR 7.7S 49.4E, APPROXIMATELY 285 NM NORTH OF MADAGASCAR. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS THE LOW LEVEL CIRCULATION CENTER HAS BECOME PARTIALLY EXPOSED AS THE ASSOCIATED CONVECTION BECAME SHEARED SOUTHEASTWARD. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM HAS MOVED SOUTH OF THE RIDGE AXIS IN AN AREA OF MODERATE 15-KNOT VERTICAL WIND SHEAR. HOWEVER, ANIMATED WATER VAPOR IMAGERY ALSO SHOWS IMPROVED POLEWARD OUTFLOW THAT IS SUSTAINING THE WAYWARD CONVECTION. NUMERIC MODELS SHOW MINIMAL DEVELOPMENT OF THE SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
