On the forecast track, the center of Milton will move away from Florida and to the north of the Bahamas today. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Gradual weakening is expected, but Milton is forecast to become a powerful extratropical low tonight. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). A sustained wind of 75 mph (121 km/h) and a gust to 83 mph (134 km/h) was recently reported at a Weatherstem station in Marineland.

HAZARDS AFFECTING LAND ---------------------- Key Messages for Milton can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Sebastian Inlet, FL to Altamaha Sound, GA...3-5 ft St. Johns River...2-4 ft Middle of Longboat Key, FL to Bonita Beach, FL...2-4 ft Charlotte Harbor...2-4 ft The deepest water will occur along the immediate coast near and to the south of the landfall location, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at4.shtml?peakSurge. RAINFALL: Additional rainfall amounts of 2 to 4 inches are expected across portions of the east-central to northeast Florida coast through this morning. This rainfall will continue to bring the risk of considerable flash and urban flooding, along with moderate to major river flooding. For a complete depiction of forecast rainfall associated with Hurricane Milton, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at4.shtml?ero. WIND: Hurricane conditions are occurring within the hurricane warning area in Florida. Tropical storm conditions are occurring in the tropical storm warning areas in Florida, Georgia, South Carolina, and the Bahamas. SURF: Swells generated by Milton are expected to continue to affect portions of the southeast U.S. and the Bahamas during the next couple of days. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
