ZCZC MIATCUAT5 ALL TTAA00 KNHC DDHHMM Hurricane Idalia Tropical Cyclone Update NWS National Hurricane Center Miami FL AL102023 700 AM EDT Wed Aug 30 2023 ...CATASTROPHIC STORM SURGE AND DESTRUCTIVE WINDS OCCURRING IN THE FLORIDA BIG BEND REGION... ...7 AM POSITION UPDATE... Radar and Air Force Reserve Hurricane Hunter aircraft data indicate that an eyewall replacement cycle has begun. Idalia's maximum sustained winds are now estimated near 125 mph (205 km/h) with higher gusts. This change in wind speed does not diminish the threat of catastrophic storm surge and damaging winds. The estimated minimum pressure indicated by Air Force Reserve Hurricane Hunter aircraft data is 947 mb (27.96 inches). Within the past hour, a C-MAN station on Cedar Key measured sustained winds of 47 mph (76 km/h), with a gust to 55 mph (88 km/h), and a Weatherflow station at Apalachee Bay measured a sustained wind of 43 mph (69 km/h), with a gust to 55 mph (88 km/h). A Florida Coastal Monitoring Program tower near Lake City, Florida, recently reported a wind gust to 51 mph (82 km/h). A NOAA National Ocean Service tide gauge at Cedar Key, Florida, recently reported a water level of 5.2 feet above mean higher high water, which is an approximation of inundation in that area.
