REMARKS:
290300Z4 POSITION NEAR 20.0N2 86.7E1.
TROPICAL CYCLONE (TC) 05B HAS TRACKED NORTHWESTWARD AT 6 KNOTS
DURING THE PAST 12 HOURS. TC 05B IS NOW LOCATED APPROXIMATELY 188 NM
SOUTH-SOUTHWEST OF CALCUTTA, INDIA. THE WARNING POSITION IS BASED ON
292330Z9 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 140 KNOTS. TC 05B
REMAINS UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE AND IS
FORECAST TO TRACK MORE NORTHWARD THROUGH A WEAKNESS IN THE RIDGE AND
RECURVE TO THE NORTHEAST. WITHIN THE NEXT 3 HOURS, TC 05B IS
FORECAST TO MAKE LANDFALL 35 NM EAST OF CUTTACK, INDIA. THE SYSTEM
HAS MAINTAINED INTENSITY OVER THE PAST 12 HOURS AND HAS BEGUN TO
SHOW SIGNS OF WEAKENING. CONTINUED INTERACTION WITH LAND AND
INCREASING VERTICAL WIND SHEAR WILL WEAKEN THE SYSTEM. ALSO AS IT
MOVES INLAND, THE SYSTEM WILL BEGIN EXTRATROPICAL TRANSITION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290000Z1 IS 22 FEET. REFER TO
WWIO30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT
291500Z7 (DTG 291351Z1) AND 300300Z6 (DTG 300151Z0).//
