Re: SIO: INVEST 99S
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.0S
89.5E, IS NOW LOCATED NEAR 14.1S 91.0E, APPROXIMATELY 366 NM WEST-
SOUTHWEST OF COCOS ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS IMPROVED DEEP CENTRAL CONVECTION ASSOCIATED WITH A SLOWLY-
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). A 031027Z AMSU-B
MICROWAVE IMAGE REVEALS THE BULK OF THE DEEP CONVECTION OVER THE
SOUTHWESTERN QUADRANT WRAPPING INTO THE LLCC. UPPER-LEVEL ANALYSIS
INDICATES THE DISTURBANCE IS NOW LOCATED IN A FAVORABLE ENVIRONMENT
WITH LOW (05 TO 10 KNOT) VERTICAL WIND SHEAR AND GOOD DUAL OUTFLOW
AS EVIDENT ON THE WATER VAPOR IMAGERY. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. DUE TO INCREASED DEEP CONVECTION AND
IMPROVED ORGANIZATION, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
1000hPa at 00z.
