TROPICAL CYCLONE 02B (ARNAB), LOCATED APPROXIMATELY 527 NM SOUTHWEST OF KOLKATA, INDIA, HAS TRACKED NORTHEASTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. AS TROPICAL CYCLONE (TC) 02B APPROACHED LAND THIS MORNING, IT RAPIDLY DECLERATED, AND TURNING SOUTHWESTWARD, DUE TO THE COMBINED EFFECTS OF LAND INTERACTION AND BINARY INTERACTION WITH INVEST 90B TO THE EAST. THE SYSTEM SKIRTED THE COAST OF THE GODAVARI RIVER DELTA, REACHING A POSITION SOUTHWEST OF NARSAPUR BY 0000Z. SINCE THAT TIME, THE SYSTEM HAS SLOWLY DRIFTED NORTHWARD AND IS NOW SITUATED ALONG THE COASTLINE, IN THE VICINITY OF NARSAPUR BASED ON ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) AND RADAR DATA FROM IMD. SURFACE OBS FROM NARSAPUR REPORT LIGHT WINDS, AND MEAN SEA LEVEL PRESSURE OF 988MB, WHICH SUPPORTS THE INITIAL INTENSITY OF 55 KNOTS WITH MEDIUM CONFIDENCE. NOW THAT INVEST 90B HAS MADE LANDFALL AND IS MOVING RAPIDLY NORTHWESTWARD INTO INTERIOR INDIA, 02B SHOULD START LIFTING NORTHWARD, MOVING ALONG THE WESTERN SIDE OF THE SUBTROPICAL RIDGE (STR) TO THE EAST. 02B WILL CONTINUE TO STEADILY WEAKEN OVER THE NEXT 36 HOURS, BEFORE DISSIPATING OVER NORTHEASTERN INDIA. 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. MINIMUM CENTRAL PRESSURE AT 280600Z IS 988 MB. // 0226102118 118N 887E 20 0226102200 126N 887E 20 0226102206 133N 887E 20 0226102212 144N 888E 20 0226102218 150N 889E 25 0226102300 153N 888E 20 0226102306 156N 889E 20 0226102312 158N 890E 20 0226102318 160N 893E 25 0226102400 161N 898E 25 0226102406 161N 903E 25 0226102412 161N 907E 25 0226102418 160N 912E 30 0226102500 158N 912E 30 0226102506 158N 909E 30 0226102512 159N 902E 30 0226102518 156N 893E 35 0226102600 153N 888E 50 0226102600 153N 888E 50 0226102606 153N 886E 65 0226102606 153N 886E 65 0226102606 153N 886E 65 0226102612 159N 872E 80 0226102612 159N 872E 80 0226102612 159N 872E 80 0226102618 160N 858E 90 0226102618 160N 858E 90 0226102618 160N 858E 90 0226102700 160N 847E 100 0226102700 160N 847E 100 0226102700 160N 847E 100 0226102706 162N 838E 115 0226102706 162N 838E 115 0226102706 162N 838E 115 0226102712 164N 826E 120 0226102712 164N 826E 120 0226102712 164N 826E 120 0226102718 163N 819E 95 0226102718 163N 819E 95 0226102718 163N 819E 95 0226102800 162N 816E 75 0226102800 162N 816E 75 0226102800 162N 816E 75 0226102806 164N 818E 55 0226102806 164N 818E 55 NNNN
