DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the eye of Hurricane Milton was located near latitude 23.8 North, longitude 86.0 West. Milton is moving toward the northeast near 12 mph (19 km/h). A northeastward motion with some increase in forward speed is expected through tonight. A turn toward the east-northeast and east is expected on Thursday and Friday. On the forecast track, the center of Milton will move across the eastern Gulf of Mexico today, make landfall along the west-central coast of Florida late tonight or early Thursday morning, and move off the east coast of Florida over the Atlantic Ocean Thursday afternoon. Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Milton is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fluctuations in intensity are likely while Milton moves across the eastern Gulf of Mexico, but Milton is expected to be a dangerous major hurricane when it reaches the west-central coast of Florida. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The minimum central pressure estimated from Hurricane Hunter aircraft observations is 914 mb (26.99 inches). 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... Egmont Key, FL to Boca Grande, FL...10-15 ft Tampa Bay...10-15 ft Anclote River, FL to Egmont Key, FL...9-13 ft Boca Grande, FL to Bonita Beach, FL...8-12 ft Charlotte Harbor...8-12 ft Bonita Beach, FL to Chokoloskee, FL...5-8 ft Aripeka, FL to Anclote River, FL...5-8 ft Chokoloskee, FL to Flamingo, FL...3-5 ft Sebastian Inlet, FL to Altamaha Sound, GA...3-5 ft Altamaha Sound, GA to Edisto Beach, SC...2-4 ft Suwannee River, FL to Aripeka, FL...2-4 ft Dry Tortugas...2-4 ft St. Johns River...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: Rainfall amounts of 6 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 catastrophic and life-threatening flash and urban flooding, along with moderate to major river flooding. Additional rainfall amounts of 2 to 4 inches, with isolated totals around 6 inches, are expected across northern portions of the Yucatan Peninsula. 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 expected in the hurricane warning area across Florida beginning this evening through early Thursday and are possible in the hurricane watch area on Thursday. Tropical storm conditions are expected to begin in the warning area on the west coast of Florida around midday, spreading across the peninsula and reaching the east coast tonight. Tropical storm conditions are expected to begin in the warning area on the east coast of Florida tonight. Tropical storm conditions are expected in portions of the northwestern Bahamas on Thursday. Tropical storm conditions are possible within the watch area on the Georgia and South Carolina coasts on Thursday. TORNADOES: A few tornadoes are possible over central and southern Florida through Thursday night. SURF: Swells generated by Milton are expected to continue to affect much of the Gulf Coast during the next day or two, and are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Cangialosi
