DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the eye of Hurricane Milton was located near latitude 21.9 North, longitude 90.4 West. Milton is moving toward the east near 10 mph (17 km/h). This general motion is expected through tonight followed by a turn toward the east-northeast and northeast on Tuesday and Wednesday. On the forecast track, the center of Milton is forecast to move near or just north of the Yucatan Peninsula tonight and Tuesday, then cross the eastern Gulf of Mexico and approach the west coast of the Florida Peninsula on Wednesday. Hurricane Hunter aircraft indicate that the maximum sustained winds remain near 180 mph (285 km/h) with higher gusts. Milton is a potentially catastrophic category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. While fluctuations in intensity are expected, Milton is forecast to remain an extremely dangerous hurricane through landfall in Florida. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km). The minimum central pressure estimated from Hurricane Hunter aircraft observations is 897 mb (26.49 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: 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 Flagler/Volusia County Line, FL to Altamaha Sound, GA...3-5 ft Sebastian Inlet, FL to Flagler/Volusia County Line, FL...2-4 ft Altamaha Sound, GA to Edisto Beach, SC...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 5 to 10 inches, with localized totals up to 15 inches, are expected across portions of the Florida Peninsula through Thursday. This rainfall brings the risk of considerable flash, urban, and areal flooding, along with the potential for moderate to major river flooding. Milton will also produce rainfall totals 4 to 7 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. 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 warning area in Mexico within a few hours, with tropical storm conditions currently occurring. Hurricane conditions are possible in the watch areas in Mexico beginning tonight and Tuesday, and tropical storm conditions are expected in the tropical storm warning area beginning tonight. Hurricane conditions are expected in the warning area on the west coast of Florida as early as Wednesday afternoon, with tropical storm conditions beginning early Wednesday. Hurricane conditions could begin along the east coast of Florida in the watch areas on Wednesday night, with tropical storm conditions possible beginning Wednesday afternoon. Tropical storm conditions are expected in the tropical storm warning areas in Florida beginning early Wednesday and will spread northward through the day. Tropical storm conditions are possible within the watch area on the east coast of Florida by Wednesday night and along the Georgia and South Carolina coasts on Thursday. SURF: Swells generated by Milton are expected to continue to affect much of the Gulf Coast within 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 1000 PM CDT. $$ Forecaster Pasch/Papin
