DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Hurricane Milton was located near latitude 22.7 North, longitude 87.5 West. Milton wobbled earlier today, but the longer-term motion is toward the east-northeast near 9 mph (15 km/h). A turn toward the northeast with an increase in forward speed is expected to begin tonight and continue through early Thursday. 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 through Wednesday, make landfall along the west-central coast of Florida Wednesday night, and move off the east coast of Florida over the Atlantic Ocean on Thursday. Satellite images indicate that maximum sustained winds have increased to near 165 mph (270 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 Wednesday night. 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 estimated minimum central pressure is 918 mb (27.11 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 2 to 4 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...8-12 ft Charlotte Harbor...8-12 ft Chassahowitzka, FL to Anclote River, FL...5-10 ft Bonita Beach, FL to Chokoloskee, FL...5-8 ft Chokoloskee, FL to Flamingo, FL...3-5 ft Yankeetown, FL to Chassahowitzka, 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 Yankeetown, 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: Tropical storm conditions will continue in the warning areas in Mexico this evening. Hurricane conditions are expected in the hurricane warning area across Florida beginning late Wednesday through early Thursday. Tropical storm conditions are expected to begin in the warning area on the west coast of Florida around midday Wednesday, spreading across the peninsula and reaching the east coast Wednesday evening. Tropical storm conditions are possible within the watch area on the Georgia and South Carolina coasts on Thursday. Tropical storm conditions are expected in the extreme northwestern Bahamas on Thursday. TORNADOES: A few tornadoes are possible over central and southern Florida beginning late tonight and continuing through early Thursday morning. 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 intermediate advisory at 700 PM CDT. Next complete advisory at 1000 PM CDT. $$ Forecaster Berg
