For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Hurricane Ian was located near latitude 27.5 North, longitude 81.4 West. Ian is moving toward the north-northeast near 8 mph (13 km/h), and a turn toward the northeast and north is expected during the next couple of days. On the forecast track, the center of Ian is expected to move across central Florida overnight and Thursday morning and emerge over the western Atlantic by late Thursday. Ian is forecast to turn northward on Friday and approach the northeastern Florida, Georgia and South Carolina coasts. Maximum sustained winds have decreased to near 90 mph (150 km/h) with higher gusts. Further weakening is expected for the next day or so, but Ian could be near hurricane strength when it moves over the Florida East coast tomorrow, and when it approaches the northeastern Florida, Georgia and South Carolina coasts on Friday. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 972 mb (28.71 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Ian 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 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... * Englewood to Bonita Beach, including Charlotte Harbor...8-10 ft * Bonita Beach to Chokoloskee...5-8 ft * Flagler/Volusia County Line to Altamaha Sound...4-6 ft * Chokoloskee to East Cape Sable...3-5 ft * Altamaha Sound to South Santee River...3-5 ft * St. Johns River north of Julington...3-5 ft * St. Johns River south of Julington...2-4 ft * Suwannee River to Middle of Longboat Key, including Tampa Bay...2-4 ft * South Santee River to Little River Inlet...2-4 ft * East Cape Sable to Card Sound Bridge...1-3 ft * Patrick Air Force Base to Flagler/Volusia County Line...1-3 ft * East of Little River Inlet to Cape Lookout...1-3 ft * Florida Keys...1-3 ft The deepest water will occur along the immediate coast near and to the right of the center, where the surge will be accompanied by large 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. WIND: Severe and extensive wind damage is likely near the core of Ian. Hurricane conditions are ongoing within the Hurricane Warning area now and will slowly spread northeastward overnight. Hurricane conditions are expected to begin along the east coast of Florida in the Hurricane Warning area starting early Thursday. Hurricane conditions are possible in the Hurricane Watch area on Thursday through late Friday. Tropical storm conditions are occuring in parts of the warning area on the east coast of Florida and should spread northward through the northeast Florida, Georgia and South Carolina coasts tonight and Thursday. Tropical storm conditions are possible in the Tropical Storm Watch area starting on Friday. RAINFALL: Ian is expected to produce the following storm total rainfall amounts: * Central and Northeast Florida: 12 to 20 inches, with local maxima up to 30 inches. * Coastal Georgia and Low Country of South Carolina: 4 to 8 inches, with local maxima of 12 inches. * Upstate and central South Carolina, North Carolina, and southern Virginia: 3 to 6 inches with local maxima of 8 inches across western North Carolina. Widespread, life-threatening catastrophic flash and urban flooding, with major to record flooding along rivers, will continue across central Florida. Widespread considerable flash, urban, and river flooding is expected across portions of northeast Florida, southeastern Georgia, and eastern South Carolina tomorrow through the weekend. Locally considerable flash, urban, and river flooding is possible this weekend across portions of the southern Appalachians with limited flooding possible across portions of southern Mid-Atlantic. TORNADOES: A tornado or two remains possible across parts of east-central and northeast Florida through Thursday morning. This threat will shift into the coastal Carolinas on Friday. SURF: Swells generated by Ian are affecting the northern coast of Cuba, the northeastern coast of the Yucatan peninsula and west coast of Florida. Swells will increase along the east coast of Florida, Georgia, and South Carolina tonight and Thursday. These swells are likely to cause life-threatening surf and rip current conditions.
