REMARKS:
120900Z POSITION NEAR 13.2N 80.2E.
TROPICAL CYCLONE (TC) 05B (VARDAH), LOCATED APPROXIMATELY 718 NM
SOUTHWEST OF CALCUTTA, INDIA, HAS TRACKED WESTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
AND A 120432Z AMSU 89 GHZ IMAGE DEPICT A RAGGED, CLOUD-FILLED EYE
FEATURE WITH TIGHTLY CURVED CONVECTIVE BANDING WRAPPING INTO THE
SYSTEM. THIS DATA SUPPORTS THE CURRENT BEST TRACK POSITION WITH HIGH
CONFIDENCE. AS OF 120700Z THE CENTER OF TC VARDAH HAS MADE LANDFALL
NEAR CHENNAI, INDIA AS A 75 KNOT SYSTEM, WHICH IS SUPPORTED BY MULTI-
AGENCY AND OBJECTIVE DVORAK INTENSITY ESTIMATES. TC 05B IS BEING
STEERED WESTWARD ALONG THE PERIPHERY OF A DEEP-LAYERED STR OVER THE
BAY OF BENGAL. THIS SYSTEM IS FORECAST TO REMAIN OVER LAND WHICH
WILL RESULT IN RAPID WEAKENING AND FULL DISSIPATION BY TAU 24.
DYNAMIC MODEL GUIDANCE REMAINS IN GOOD AGREEMENT LENDING HIGH
CONFIDENCE TO THE JTWC FORECAST TRACK. THIS IS THE FINAL WARNING ON
THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 120600Z IS 12 FEET.//
