DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Post-Tropical Cyclone Milton was located near latitude 29.3 North, longitude 77.5 West. Milton is moving toward the east-northeast near 21 mph (33 km/h). A turn toward the east is expected later today, with that motion forecast to continue over the western Atlantic for the next few days. On the forecast track, the center of Milton will continue to move away from the east coast of Florida and pass north of the northwestern Bahamas this afternoon. Satellite-derived wind data indicate Milton has become a powerful post-tropical cyclone with maximum sustained winds near 75 mph (120 km/h) with higher gusts. Gradual weakening is expected during the next several days. Hurricane-force winds extend outward up to 70 miles (110 km) northwest of the center and tropical-storm-force winds extend outward up to 310 miles (500 km). The estimated minimum central pressure is 983 mb (29.03 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... Flagler/Volusia County Line, FL to Altamaha Sound, GA...3-5 ft St. Johns River...2-4 ft The deepest water will occur along the immediate coast in areas of onshore winds, 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 around an inch are possible along the northeastern coast of Florida through today. In the wake of heavy rainfall from Milton, the risk of considerable urban flooding will linger through this morning across east central Florida. Moderate to major river flooding is ongoing and forecast throughout central Florida. For a complete depiction of forecast rainfall associated with Post-Tropical Cyclone 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: Tropical storm conditions will continue within the tropical storm warning areas in Florida, Georgia, and South Carolina for the next few hours. 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.
