TROPICAL CYCLONE 07B (MIDHILI) WARNING NR 004 01 ACTIVE TROPICAL CYCLONE IN NORTHIO MAX SUSTAINED WINDS BASED ON ONE-MINUTE AVERAGE WIND RADII VALID OVER OPEN WATER ONLY --- WARNING POSITION: 171200Z --- NEAR 23.2N 91.2E MOVEMENT PAST SIX HOURS - 035 DEGREES AT 21 KTS POSITION ACCURATE TO WITHIN 060 NM POSITION BASED ON CENTER LOCATED BY SATELLITE PRESENT WIND DISTRIBUTION: MAX SUSTAINED WINDS - 035 KT, GUSTS 045 KT WIND RADII VALID OVER OPEN WATER ONLY DISSIPATING AS A SIGNIFICANT TROPICAL CYCLONE OVER LAND RADIUS OF 034 KT WINDS - 060 NM NORTHEAST QUADRANT 070 NM SOUTHEAST QUADRANT 050 NM SOUTHWEST QUADRANT 060 NM NORTHWEST QUADRANT REPEAT POSIT: 23.2N 91.2E --- FORECASTS: 12 HRS, VALID AT: 180000Z --- 24.9N 92.5E MAX SUSTAINED WINDS - 025 KT, GUSTS 035 KT WIND RADII VALID OVER OPEN WATER ONLY DISSIPATED AS A SIGNIFICANT TROPICAL CYCLONE OVER LAND --- REMARKS: 171500Z POSITION NEAR 23.6N 91.5E. 17NOV23. TROPICAL CYCLONE 07B (MIDHILI), LOCATED APPROXIMATELY 63 NM NORTH-NORTHWEST OF CHITTAGONG, HAS TRACKED NORTHEASTWARD AT 21 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS AN EXPOSED, IRREGULAR LOW LEVEL CIRCULATION CENTER (LLCC) OVER LAND TO THE NORTHWEST OF CHITTAGONG, BANGLADESH. THE SYSTEM MADE LANDFALL AROUND THE 0700Z AND HAS CONTINUED TO MOVE RAPIDLY INLAND ALONG THE WESTERN SIDE OF THE STEERING RIDGE. SURFACE OBSERVATIONS FROM HATIA PEAKED AT 0900Z AT 51 KNOTS, LIKELY A GUST READING, BUT ARE STILL SUSTAINED AT 25 KNOTS AT 1200Z, SUPPORTING THE INITIAL INTENSITY OF 35 KNOTS EVEN THOUGH THE SYSTEM IS OVER LAND. NOW THAT THE SYSTEM IS MOVING INLAND, FRICTIONAL EFFECTS WILL RAPIDLY ERODE THE LOW-LEVEL VORTEX, LEADING TO RAPID WEAKENING AND DISSIPATION OVER FAR NORTHEASTERN BANGLADESH WITHIN THE NEXT 12 HOURS. 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 171200Z IS 1004 MB.// NNNN
