AN AREA OF CONVECTION HAS PERSISTED NEAR 5.1S 64.6E,
APPROXIMATELY 485 NM WEST-NORTHWEST OF DIEGO GARCIA. ANIMATED
INFRARED AND MULTISPECTRAL SATELLITE IMAGERY DEPICTS PERSISTENT DEEP
CONVECTION ASSOCIATED WITH A SLOWLY-CONSOLIDATING LOW-LEVEL
CIRCULATION CENTER. AN 180025Z SSMIS MICROWAVE IMAGE REVEALS THE
BULK OF THE CONVECTIVE BANDING OVER THE SOUTHWESTERN QUADRANT
WRAPPING TOWARDS THE CENTER. UPPER-LEVEL ANALYSIS INDICATES THE
DISTURBANCE IS LOCATED IN A MARGINALLY FAVORABLE ENVIRONMENT WITH
MODERATE 10 TO 20 KNOT VERTICAL WIND SHEAR AND FAIR OUTFLOW.
ADDITIONALLY, WARM SEA SURFACE TEMPERATURES IN THE AREA ARE
CONDUCIVE FOR DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW. |
