Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests in the remainder of the Yucatan peninsula of Mexico, the Florida Peninsula, the Florida Keys, and the northwestern Bahamas should monitor the progress of this system. Additional watches and warnings will likely be issued this afternoon. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the eye of Hurricane Milton was located by an Air Force Reserve Hurricane Hunter aircraft near latitude 21.7 North, longitude 91.3 West. Milton is moving toward the east near 9 mph (15 km/h). This general motion is expected today followed by a turn toward the east-northeast and northeast on Tuesday and Wednesday. On the forecast track, Milton is forecast to move near or just north of the Yucatan Peninsula today and Tuesday, then cross the eastern Gulf of Mexico and approach the west coast of the Florida Peninsula by Wednesday. Data from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 175 mph (280 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 estimated minimum central pressure is 911 mb (26.90 inches) based on Air Force Reserve dropsonde data. HAZARDS AFFECTING LAND ---------------------- Key Messages for Hurricane 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...8-12 ft Tampa Bay...8-12 ft Yankeetown, FL to Anclote River, FL...5-10 ft Englewood, FL to Bonita Beach, FL...5-10 ft Charlotte Harbor...5-10 ft Bonita Beach, FL to Chokoloskee, FL...4-7 ft Suwannee River, FL to Yankeetown, FL...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 10 inches, with localized totals up to 15 inches, are expected across portions of the Florida Peninsula and the Keys through Wednesday night. 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 of 2 to 4 inches with isolated totals around 6 inches 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 beginning late today or tonight, with tropical storm conditions expected to begin this afternoon. 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 later today. Hurricane conditions are possible in the Hurricane Watch area in Florida on Wednesday, and tropical storm conditions are possible in the Tropical Storm Watch area on Wednesday. SURF: Swells generated by the system are expected to continue to affect much of the whole Gulf Coast within the next day or two, and are likely to cause life-threatening surf and rip current conditions.
