REMARKS:
281500Z6 POSITION NEAR 18.9N8 87.5E0.
TROPICAL CYCLONE (TC) 05B HAS TRACKED NORTHWESTWARD AT 8 KNOTS
AND RAPIDLY INTENSIFIED DURING THE PAST 12 HOURS. TC 05B IS NOW
LOCATED APPROXIMATELY 230 NM SOUTH OF CALCUTTA, INDIA. THE WARNING
POSITION IS BASED ON 291130Z6 INFRARED AND MICROWAVE SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 127 AND 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. AT APPROXIMATELY 290400Z5, TC 05B IS FORECAST TO MAKE
LANDFALL 40 NM EAST OF CUTTACK, INDIA. TC 05B IS IN A FAVORABLE
ENVIRONMENT FOR CONTINUED DEVELOPMENT, BUT AS TC 05B TRACKS MORE
NORTHWARD ITS INTERACTION WITH LAND AND INCREASING VERTICAL WIND
SHEAR WILL WEAKEN THE SYSTEM. ALSO AS IT MOVES INLAND IT WILL PICK
UP JET SUPPORT, WHICH WILL SERVE TO MOVE THE SYSTEM RAPIDLY TO THE
EAST AS IT BEGINS EXTRATROPICAL TRANSITION. MAXIMUM SIGNIFICANT WAVE

HEIGHT AT 281200Z IS 22 FEET. REFER TO WWPW30 RJTX FOR ADDITIONAL
SEA HEIGHT INFORMATION. NEXT WARNINGS AT 290300Z4 (DTG 290151Z8) AND

291500Z7 (DTG 291351Z1).//
