Milton is an extremely dangerous category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

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: A storm surge will raise water levels by as much as 4 to 6 feet above ground level along the northern coast of the Yucatan Peninsula in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. 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... Anclote River, FL to Englewood, FL...10-15 ft Tampa Bay...10-15 ft Englewood, FL to Bonita Beach, FL...6-10 ft Charlotte Harbor...6-10 ft Yankeetown, FL to Anclote River, FL...5-10 ft Bonita Beach, FL to Chokoloskee, FL...4-7 ft Suwannee River, FL to Yankeetown, FL...3-5 ft Chokoloskee, FL to Flamingo, FL...3-5 ft Volusia/Brevard County Line, FL to Altamaha Sound, GA...3-5 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: Rainfall amounts of 5 to 12 inches, with localized totals up to 18 inches, are expected across central to northern portions of the Florida Peninsula through Thursday. This rainfall brings the risk of life-threatening flash, urban and areal flooding along with moderate to major river flooding. Milton will also produce rainfall totals 2 to 4 inches across the Florida Keys through Thursday. In addition, rainfall amounts of 2 to 4 inches with isolated totals around 6 inches are expected across northern portions of the Yucatan Peninsula.
