A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. 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. 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 near latitude 22.5 North, longitude 88.2 West. Although Milton has been wobbling during the past few hours, its longer-term motion is toward the east-northeast near 8 mph (13 km/h). A turn toward the northeast with an increase in forward speed is expected to begin later today and continue through Thursday. On the forecast track, the center of Milton will move across the eastern Gulf of Mexico and approach the west-central coast of Florida through Wednesday. The center is likely to make landfall along the west-central coast of Florida on Wednesday night, and move east-northeastward across central Florida through Thursday. Aircraft reconnaissance data and satellite images indicate that maximum sustained winds have increased to near 155 mph (250 km/h) with higher gusts. Milton is a category 4 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 105 miles (165 km). The minimum central pressure based on dropsonde data is 923 mb (27.26 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...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 Port Canaveral, FL to Altamaha Sound, GA...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 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 life-threatening flash and urban flooding, along with moderate to major river flooding. Milton will also produce rainfall totals 2 to 4 inches across the Florida Keys through Thursday. 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: Hurricane and tropical storm conditions will continue in the warning areas in Mexico today. 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 Wednesday morning, 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 possible in the extreme northwestern Bahamas on Thursday. TORNADOES: A few tornadoes are possible over central and southern Florida beginning late tonight and continuing through Wednesday night. 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 400 PM CDT. $$ Forecaster Berg

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Tue Oct 8 2024

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Leslie, located over the central tropical Atlantic Ocean, and
on Hurricane Milton, located over the southern Gulf of Mexico.

Southwestern Atlantic:
A non-tropical area of low pressure located just northeast of the
northwestern Bahamas is producing gale-force winds. This system
could acquire some tropical or subtropical characteristics over the
next day or so while the low moves northeastward to east-
northeastward around 15 mph. Upper-level winds are likely to
increase by Wednesday night, which should end any chances for
further development. Additional information on this system,
including gale warnings, can be found in High Seas Forecasts issued
by the National Weather Service.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.

Eastern Tropical Atlantic:
A tropical wave is expected to move off the west coast of Africa in
a day or two. Afterward, environmental conditions appear only
marginally favorable for some limited development of this system
while it moves westward or west-northwestward across the eastern
tropical Atlantic, moving near the Cabo Verde Islands late Thursday
through Friday.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

Hurricane Milton Forecast Discussion Number 14

Tue, 10/08/2024 - 9:56am
Issued at 1000 AM CDT Tue Oct 08 2024 000 WTNT44 KNHC 081455 TCDAT4 Hurricane Milton Discussion Number 14 NWS National Hurricane Center Miami FL AL142024 1000 AM CDT Tue Oct 08 2024 Sequences of microwave images and recent Hurricane Hunter observations suggest that Milton completed an eyewall replacement overnight, and the new eyewall has contracted down from 22 n mi to 12 nm in diameter. However, it does not appear that the hurricane weakened much after the eyewall replacement, and it could have rebounded with the outer eyewall contraction. A dropsonde released by the NOAA P-3 in the northeastern eyewall recently measured an average wind of 156 kt in the lowest 150 m of the sounding, which equates to an intensity of 130 kt. The latest pressure reported by the planes is 929 mb. The recent aircraft fixes show that Milton has turned a bit leftward and is moving toward the east-northeast (065/8 kt). Milton is forecast to turn northeastward and begin accelerating later today as it moves between a trough digging into the Gulf of Mexico and a ridge near the Greater Antilles. The track guidance is honed in on a landfall along the west-central coast of Florida sometime Wednesday night. However, it is critical to remember that even at 36-48 hours away, NHC's track forecasts can be off by an average of 60-70 n mi, which means we still can't pinpoint an exact landfall location, especially if the hurricane wobbles as it approaches the coast. After landfall, Milton is forecast to cross Florida and emerge over the Atlantic waters on Thursday. Milton is expected to maintain major hurricane strength while it moves across the Gulf of Mexico and approaches the west coast of Florida. Stronger vertical shear is expected to set in about 24 hours, but even if this causes some weakening, it will not be enough to keep Milton from being an extremely dangerous hurricane when it reaches shore. Additionally, the first stages of extratropical transition may be just underway as Milton is reaching the coast, which could impart some baroclinic energy and slow the rate of weakening. The NHC intensity forecast is close to the top end of the model envelope, which includes the GFS and ECMWF models, since these models should have a better handle on a potential positive trough interaction. Milton's wind field is expected to expand as it approaches Florida. In fact, the official forecast shows the hurricane and tropical-storm-force winds roughly doubling in size by the time it makes landfall. Therefore, damaging winds, life-threatening storm surge, and heavy rainfall will extend well outside the forecast cone. It is worth emphasizing that 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 today. Milton has the potential to be one of the most destructive hurricanes on record for west-central Florida. Key Messages: 1. Damaging hurricane-force winds and a life-threatening storm surge with destructive waves are expected across portions of the northern coast of the Yucatan Peninsula today. 2. 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, and you should evacuate today if ordered by local officials. There will likely not be enough time to wait to leave on Wednesday. 3. 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 as 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, and to be ready for long-duration power outages, should be complete by tonight. 4. Heavy rainfall across the Florida Peninsula through Thursday brings the risk of 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 1000 AM CDT (1500 UTC), the center of Hurricane Milton was located near latitude 22.7 North, longitude 88.4 West. Milton is moving 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 later today and continue through Thursday. On the forecast track, the center of Milton will move across the eastern Gulf of Mexico and approach the west-central coast of Florida through Wednesday. The center is likely to make landfall along the west-central coast of Florida on Wednesday night, and move east-northeastward across central Florida through Thursday. Maximum sustained winds are near 150 mph (240 km/h) with higher gusts. Milton is a category 4 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 105 miles (165 km). The minimum central pressure based on dropsonde data is 929 mb (27.44 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...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 Port Canaveral, FL to Altamaha Sound, GA...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 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 life-threatening flash and urban flooding, along with moderate to major river flooding. Milton will also produce rainfall totals 2 to 4 inches across the Florida Keys through Thursday. 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: Hurricane and tropical storm conditions will continue in the warning areas in Mexico today. 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 Wednesday morning, 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 possible in the extreme northwestern Bahamas on Thursday. TORNADOES: A few tornadoes are possible over central and southern Florida beginning late tonight and continuing through Wednesday night. 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 100 PM CDT. Next complete advisory at 400 PM CDT. $$ Forecaster Berg

Tropical Storm Leslie Forecast Discussion Number 25

Tue, 10/08/2024 - 9:36am
Issued at 1100 AM AST Tue Oct 08 2024 000 WTNT43 KNHC 081436 TCDAT3 Tropical Storm Leslie Discussion Number 25 NWS National Hurricane Center Miami FL AL132024 1100 AM AST Tue Oct 08 2024 Satellite images show Leslie has made a bit of a comeback this morning, with convection trying to wrap around the center. Microwave passes also display that Leslie still has some inner-core features including a partial eyewall. Overall, Dvorak estimates are about the same as earlier, so the initial wind speed will stay 60 kt. Plentiful dry air in the mid-levels of the atmosphere has been preventing sustained deep convection near Leslie, despite low-to-moderate shear. Leslie does have a short window where the shear diminishes later today and tomorrow, though Leslie will also be contending with less instability near the wake of Kirk. While some of the guidance is showing re-strengthening, the above factors generally argue for little significant change during the next day or so. The new forecast is nudged higher than the previous one, but lies below the model consensus through 36 hours. After that time, the storm should encounter strong northerly flow of over 50 kt, which is forecast to cause Leslie to quickly decouple and degenerate into a remnant low by this weekend. The initial motion is estimated to be northwestward, or 310/11 kt. There are no significant track changes to report as Leslie is being steered around the southwest to northwest sides of the subtropical ridge, causing the storm's motion to change to the north late tomorrow and then recurve to the northeast later this week. Only cosmetic changes were made to the last NHC forecast.
