REMARKS:
262100Z POSITION NEAR 15.8N 85.7E.
TROPICAL CYCLONE 03B (KYANT), LOCATED APPROXIMATELY 423 NM SOUTH-
SOUTHWEST OF CALCUTTA, INDIA, HAS TRACKED WEST-SOUTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A RAPIDLY DETERIORATING SYSTEM THAT HAS
LOST MOST OF ITS CONVECTIVE STRUCTURE OVER THE LAST SIX HOURS. A
261559Z METOP-A ASCAT IMAGE SHOWS THE LOW LEVEL CIRCULATION CENTER
BECOMING ELONGATED, LENDING FAIR CONFIDENCE TO THE INITIAL POSITION,
WITH ONLY 25 KNOT WIND BARBS LOCATED ON THE NORTHEAST PERIPHERY. THE
CURRENT INTENSITY OF 30 KNOTS IS BASED ON THE ASCAT IMAGE COMBINED
WITH THE LOWER END OF DVORAK ESTIMATES RANGING FROM T2.0 TO 3.0 (30
TO 45 KNOTS). UPPER-LEVEL ANALYSIS SHOWS A POINT SOURCE JUST TO THE
EAST OF THE SYSTEM INTRODUCING SOME EASTERLY WIND SHEAR NOT
CONDUCIVE FOR REDEVELOPMENT. THE UPPER LEVEL ENVIRONMENT IS EXPECTED
TO REMAIN UNFAVORABLE AS THE DEEP-LAYERED RIDE BUILDS ESTABLISHING
PREDOMINANT EASTERLY FLOW ALOFT. THE REMNANTS OF TS KYANT IS
EXPECTED TO CONTINUE ON A TRACK TO THE WEST-SOUTHWEST ALONG THE
SOUTHERN PERIPHERY OF THE BUILDING DEEP-LAYERED RIDGE TO THE
NORTHWEST. 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 261800Z
IS 12 FEET.//
