AN AREA OF CONVECTION HAS PERSISTED NEAR 7.0S 100.1E, APPROXIMATELY 350 NM NORTH-NORTHEAST OF COCOS ISLAND, AUSTRALIA. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS A BROAD BUT CONSOLIDATING LOW LEVEL CIRCULATION CENTER WITH LIMITED CENTRAL CONVECTION. A 031128Z TRMM MICROWAVE IMAGE SHOWS A SLIGHT INCREASE IN THE DEFINITION OF THE SYSTEM AS IT HAS SLIGHTLY CONSOLIDATED IN THE LOWER LEVELS WHILE CONVECTION HAS REMAINED MINIMAL. UPPER-LEVEL ANALYSIS REVEALS A MARGINAL ENVIRONMENT AS DIVERGENT OUTFLOW IS BEING COUNTERED BY MODERATE TO STRONG (20-30 KNOTS) VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES IN THE REGION ARE FAVORABLE FOR DEVELOPMENT AT 27 TO 28 DEGREES CELSIUS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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.
