(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 11.8S 72.8E,
APPROXIMATELY 260 NM SOUTH OF DIEGO GARCIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION
CENTER (LLCC) WITH FORMATIVE CONVECTIVE BANDING WRAPPING INTO A
BROAD LLCC. A 051047Z AMSU IMAGE INDICATES FRAGMENTED DEEP
CONVECTIVE BANDING OVER THE EASTERN SEMI-CIRCLE. A 050355Z ASCAT
IMAGE SHOWS 20 TO 25 KNOT WINDS OVER THE EASTERN SEMI-CIRCLE.
SURFACE OBSERVATIONS FROM DIEGO GARCIA INDICATE 10 TO 15 KNOT WINDS
AND SLP NEAR 1007MB. UPPER-LEVEL ANALYSIS REVEALS A MARGINAL
ENVIRONMENT CHARACTERIZED BY WEAK TO MODERATE VERTICAL WIND SHEAR
AND DIFFLUENT WESTERLY FLOW. 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 LOW.
