TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.1N 91.1E, IS NOW LOCATED NEAR 5.0N 91.3E, APPROXIMATELY 240 NM WEST OF THE NORTHERN TIP OF SUMATRA. ANIMATED INFRARED SATELLITE IMAGERY INDICATES IMPROVED CONSOLIDATION OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). A 231940Z AMSR-E IMAGE DEPICTS A DEFINED LLCC WITH CURVED CONVECTIVE BANDING WRAPPING INTO THE SOUTHWEST QUADRANT. A 230336Z ASCAT PASS SHOWED A 20-25 KNOT SYSTEM. UPPER-LEVEL ANALYSIS INDICATES THAT THE LLCC IS LOCATED WELL SOUTH OF THE SUBTROPICAL RIDGE AXIS AND IS UNDER MODERATE, EASTERLY VERTICAL WIND SHEAR. DEEP CONVECTION IS BEING FUELED BY DIFFLUENT FLOW ALOFT. 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 FAIR.
