Issued at 1100 AM EDT Wed Oct 09 2024 000 WTNT44 KNHC 091456 TCDAT4 Hurricane Milton Discussion Number 18 NWS National Hurricane Center Miami FL AL142024 1100 AM EDT Wed Oct 09 2024 Milton's structure has begun to change due to the onset of strong southwesterly shear, which UW-CIMSS is analyzing to be 30-35 kt. The cloud canopy has become more asymmetric with dry air infiltrating the western side of the circulation, and the eye has also become cloud filled. The NOAA and Air Force Reserve Hurricane Hunters observed that the eye is open to the south, and a very recent dropsonde indicates that the minimum pressure is up to 931 mb. Milton's intensity is therefore set at 125 kt on this advisory. Deep-layer shear is expected to increase further today and this evening, and continued weakening is anticipated. However, since Milton only has another 12 hours or so over water, it is expected to still be a major hurricane when it makes landfall tonight. The NHC intensity forecast lies between the statistical-dynamical models and the consensus aids at 12 hours, meaning that Milton is likely to be a category 3 or 4 strength at landfall. A slow decay in the winds is expected after landfall, but Milton is anticipated to move off the east coast of Florida on Thursday still as a hurricane. On another note, Milton is expected to begin interacting with a front later this evening, which is likely to cause the wind field to expand on the hurricane's northwestern side. This will likely cause very strong, gusty winds to occur even to the north of where Milton makes landfall. Milton is moving quickly toward the northeast (035/15 kt). The track models insist that the hurricane will continue to move northeastward but slow down through the rest of today, with a turn toward the east-northeast occurring overnight. The NHC track forecast maintains continuity with the previous predictions, lying near the northern boundary of the guidance envelope and close to where the raw model fields bring the center onshore. We would like to emphasize that Milton's exact landfall location is not possible to predict even at this time, particularly if the hurricane wobbles during the day and into this evening. Even at 12-24 hours, NHC's track forecasts can be off by an average of 20-30 nm. Since storm surge forecasts are highly sensitive to the exact track, this means that the realized storm surge heights across the Tampa Bay region and south may vary widely, and there will likely be a noticeable gradient of surge heights to the north of the landfall location. However, the risk of devastating storm surge still exists across much of the west-central and southwest coast of Florida given the size of the storm and the uncertainties in exactly where landfall will occur. Finally, damaging winds, life-threatening storm surge, and heavy rainfall will extend well outside the forecast cone. This is a very serious situation and residents in Florida should closely follow orders from their local emergency management officials. Evacuations and other preparations should be completed over the next couple of hours. Key Messages: 1. A large area of destructive storm surge, with highest inundations of 10 ft or greater, is expected along a portion of the west-central coast of the Florida Peninsula. If you are in the Storm Surge Warning area, this is an extremely life-threatening situation. The time to evacuate, if told to do so by local officials, is quickly coming to a close. 2. Devastating hurricane-force winds are expected along portions of the west coast of Florida, where a Hurricane Warning is in effect. Milton is forecast to remain a hurricane while it crosses the Florida Peninsula and life-threatening hurricane-force winds, especially in gusts, are expected to spread inland across the peninsula. Preparations to protect life and property, including being ready for long-duration power outages, should be rushed to completion. 3. Heavy rainfall across the Florida Peninsula through Thursday brings the risk of catastrophic and life-threatening flash and urban flooding along with moderate to major river flooding, especially in areas where coastal and inland flooding combine to increase the overall flood threat.

DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Hurricane Milton was located near latitude 25.8 North, longitude 84.3 West. Milton is moving toward the northeast near 17 mph (28 km/h). A northeastward motion with some decrease in forward speed is expected through this evening. 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 tonight, and move off the east coast of Florida over the western Atlantic Ocean on Thursday. Maximum sustained winds are near 145 mph (230 km/h) with higher gusts. Milton is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Milton is expected to remain an extremely dangerous major hurricane when it reaches the west-central coast of Florida tonight, and remain at hurricane strength while it moves across the Florida peninsula through Thursday. Gradual weakening is forecast while Milton moves eastward over the western Atlantic, and it is likely to become an extratropical storm by early Friday. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). A NOAA saildrone (SD-1083) located approximately 80 miles northeast of the center recently reported a sustained wind of 44 mph (71 km/h) with a gust of 57 mph (91 km/h). The minimum central pressure based on Air Force Reserve Hurricane Hunter data is 931 mb (27.50 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... Anna Maria Island, FL to Boca Grande, FL...10-15 ft Anclote River, FL to Anna Maria Island, FL...8-12 ft Tampa Bay...8-12 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...3-5 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 Yankeetown, 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. 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 Thursday morning 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 in a few hours, spreading across the peninsula and reaching the east coast tonight. Tropical storm conditions are expected to begin in the warning area along the Georgia coast on Thursday. Tropical storm conditions are expected in portions of the northwestern Bahamas on Thursday. Tropical storm conditions are possible within the watch area on the South Carolina coast on Thursday. TORNADOES: Several tornadoes are likely today and tonight across parts of central and southern Florida. SURF: Swells generated by Milton are expected to continue to affect much of the Gulf Coast and will increase along the southeastern U.S. coast during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

The initial intensity is increased to 75 kt, in best agreement with the Dvorak estimates. Leslie's initial motion is estimated to be northwestward, or 305/9 kt. A gradual turn to the north is expected in about 36 h as Leslie rounds the southwestern and western periphery of a subtropical ridge to the east. Afterward, Leslie should accelerate toward the northeast in response to a strong trough approaching the cyclone from the northwest. The NHC forecast is nearly identical to the previous one and lies near the TVCN and HCCA consensus models. Leslie is forecast to remain in a favorable environment for another 12-18 h. The intensity forecast has been increased to an 85-kt peak at hour 12 and 24, and it is possible that it could strengthen a bit more than that, as suggested by the HAFS-B model. By hour 24, Leslie is expected to run into a wall of strong northerly shear caused by a strengthening upper-level anticyclone in between Milton and Leslie. The shear is expected to cause Leslie to rapidly weaken during the 24 to 48 h period. While it is possible that Leslie could lose most of its convection in 2 to 3 days, the latest GFS and ECMWF simulated satellite imagery show periodic bursts of convection continuing into Day 4. However, Leslie is likely to merge with a front and become extratropical in 3 to 4 days, and a transition to an extratropical cyclone is forecast at the end of that period.

DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the eye of Hurricane Milton was located near latitude 25.0 North, longitude 84.8 West. Milton is moving toward the northeast near 16 mph (26 km/h). A northeastward motion 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 western Atlantic Ocean Thursday afternoon. Maximum sustained winds are near 155 mph (250 km/h) with higher gusts. Milton is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Milton is expected to remain an extremely dangerous major hurricane when it reaches the west-central coast of Florida tonight. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The minimum central pressure based on NOAA and Air Force Reserve Hurricane Hunter data is 915 mb (27.02 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... Anna Maria Island, FL to Boca Grande, FL...10-15 ft Anclote River, FL to Anna Maria Island, FL...8-12 ft Tampa Bay...8-12 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...4-7 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 Yankeetown, 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. 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 and along the Georgia coast on Thursday. Tropical storm conditions are expected in portions of the northwestern Bahamas on Thursday. Tropical storm conditions are possible within the watch area on the South Carolina coast on Thursday. TORNADOES: Several tornadoes are likely today and tonight across parts of central and southern Florida. SURF: Swells generated by Milton are expected to continue to affect much of the Gulf Coast and will increase along the southeastern U.S. coast during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
