REMARKS:
THE AREA OF CONVECTION (INVEST 97B) PREVIOUSLY LOCATED
NEAR 16.0N 90.0E IS NOW LOCATED NEAR 17.5N 89.7E, APPROXIMATELY 366
NM EAST OF VISAKHAPATNAM, INDIA. ANIMATED ENHANCED INFRARED IMAGERY
AND A 191112Z SSMIS 91GHZ IMAGE DEPICT A BROAD CONSOLIDATING LOW
LEVEL CIRCULATION CENTER (LLCC) WITH CURVED DEEP CONVECTIVE BANDING.
THE UPPER LEVEL ENVIRONMENT DEPICTS A FAVORABLE ENVIRONMENT WITH LOW
TO MODERATE (10-15 KNOT) VERTICAL WIND SHEAR AND DUAL OUTFLOW. A
RECENT PARTIAL ASCAT PASS REVEALS A BROAD REGION OF 25-30 KNOT WINDS
IN THE SOUTHERN SEMI-CIRCLE. SEA SURFACE TEMPERATURES (27-29
CELSIUS) IN THE AREA ARE FAVORABLE FOR FUTURE DEVELOPMENT. GLOBAL
MODELS SHOW A SHORT LIVED TROPICAL SYSTEM DEVELOPING WITHIN 24 HOURS
AS IT TRACKS TO THE NORTHWEST. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.

The storm seems to be following similar path to Cyclone Yemyin. Any chance of it crossing the landmass and regenerating in Arabian sea?
