OF KOLKATA, INDIA, HAS TRACKED NORTH-NORTHWESTWARD AT 03 KNOTS OVER
THE PAST SIX HOURS. ANIMATED WATER VAPOR SATELLITE IMAGERY INDICATES
A CONSOLIDATING SYSTEM WITH DEEP AND EXPANSIVE CONVECTIVE BANDING TO
THE SOUTH AND FORMATIVE BANDING TO THE NORTHEAST OF A VERY BROAD
LOW-LEVEL CIRCULATION CENTER (LLCC). THE CURRENT INTENSITY IS BASED
ON DVORAK ESTIMATES FROM PGTW AND KNES OF 35 KNOTS. THE CURRENT
POSITION IS BASED ON ANIMATED INFRARED SATELLITE IMAGERY AND A
