Issued at 500 AM EDT Tue Sep 24 2024 279 WTNT44 KNHC 240859 TCDAT4 Potential Tropical Cyclone Nine Discussion Number 4 NWS National Hurricane Center Miami FL AL092024 500 AM EDT Tue Sep 24 2024 Satellite images indicate that the system remains poorly organized. A large area of deep convection is on the eastern side of the broad circulation with no defined central features, and dropsondes from the Air Force and NOAA aircraft indicate that low-level circulation remains poorly defined. The initial wind speed is kept at 30 kt, in agreement with many dropsondes around that value. The best estimate of initial motion is northwestward at about 7 kt. This general motion is expected today while the disturbance moves around a high-pressure area over the southeastern United States. The cyclone is expected to gradually turn northward on Wednesday as the high shifts eastward ahead of a mid-level trough dropping into the south-central United States. This evolution of the steering pattern should cause the system to accelerate northward to north-northeastward over the eastern Gulf of Mexico and toward the northeastern Gulf Coast through Thursday. The biggest change to the model guidance overnight is that the guidance mean is a bit slower, with the GFS model faster than most of the aids. However, this remains a very consistent set of models, and very little overall change was made to the official forecast. Hopefully an ongoing NOAA G-IV aircraft mission will help provide useful data for any future track refinements. Southwesterly shear continues over the disturbance, though the models are insistent that this shear will abate as an upper-level low over the northeastern Yucatan Peninsula weakens today and tomorrow. Otherwise, conditions look quite favorable for strengthening over the eastern Gulf of Mexico on Wednesday and Thursday, with the system likely moving over extremely deep and warm waters, along with a favorable trough interaction, and many of the forecast aids are showing rapid intensification over the eastern Gulf of Mexico. The intensity guidance is very close to the previous NHC intensity forecast and continues to indicate that this system will become quite large and powerful before landfall. Due to the forecast large size of this system, storm surge, wind, and rainfall impacts will extend well away from the center, particularly on the east side. In addition, the fast forward speed while it crosses the coast will likely result in farther inland penetration of strong winds over parts of the southeastern United States after landfall. Hurricane and Storm Surge Watches have been issued this morning, and further watches and warnings are likely later today. KEY MESSAGES: 1. The disturbance is forecast to intensify and be near hurricane strength when it reaches the far northwestern Caribbean Sea early Wednesday. Tropical storm conditions are expected over portions of western Cuba and the northeastern coast of the Yucatan Peninsula with hurricane conditions possible. 2. The system is expected to intensify into a major hurricane before it approaches the northeastern Gulf Coast on Thursday, and the potential for life-threatening storm surge and damaging hurricane-force winds along the coast of the Florida Panhandle and the Florida west gulf coast is increasing. Hurricane and Storm Surge Watches have been issued, and residents should ensure they have their hurricane plan in place, and also follow advice given by local officials. 3. Potential Tropical Cyclone Nine will bring heavy rain to portions of the western Caribbean, which will cause considerable flooding and mudslides across western Cuba. Heavy rainfall will likely result in locally considerable flash and urban flooding across portions of Florida, with isolated flash and urban flooding possible across the Southeast, Southern Appalachians, and the Tennessee Valley Wednesday through Friday. Minor to isolated moderate river flooding will be possible.

A Hurricane Watch has been issued for the Gulf Coast of Florida from Englewood northward and westward to Indian Pass, including Tampa Bay. A Tropical Storm Watch has been issued for the Gulf Coast of Florida from Indian Pass to the Walton/Bay County Line and from north of Bonita Beach to south of Englewood. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Watch is in effect for... * Indian Pass southward to Flamingo * Tampa Bay * Charlotte Harbor A Hurricane Watch is in effect for... * Cabo Catoche to Tulum, Mexico * Cuban province of Pinar del Rio * Englewood to Indian Pass * Tampa Bay A Tropical Storm Warning is in effect for... * Grand Cayman * Rio Lagartos to Tulum, Mexico * Cuban provinces of Artemisa, and Pinar del Rio, and the Isle of Youth A Tropical Storm Watch is in effect for... * Dry Tortugas * Lower Keys west of the Seven Mile Bridge * Flamingo to south of Englewood * West of Indian Pass to Walton Bay County line 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 Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 to 36 hours. 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 elsewhere along the northeastern Gulf Coast, including the Florida Panhandle and the Florida west Gulf coast, should monitor the progress of this system. Additional watches or warnings will likely be required today. 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 500 AM EDT (0900 UTC), the disturbance was centered near latitude 18.9 North, longitude 83.0 West. The system is moving toward the northwest near 8 mph (13 km/h). This general motion is expected later today and tonight, followed by a faster northward to north-northeastward motion on Wednesday and Thursday. On the forecast track, the center of the system is forecast to move across the northwestern Caribbean Sea through tonight, and then over the eastern Gulf of Mexico on Wednesday and Thursday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is expected during the next few days, and the system is forecast to become a hurricane on Wednesday and continue strengthening on Thursday as it moves across the eastern Gulf of Mexico. * Formation chance through 48 hours...high...near 100 percent. * Formation chance through 7 days...high...near 100 percent. The estimated minimum central pressure is 1001 mb (29.56 inches) based on Air Force dropsonde data. HAZARDS AFFECTING LAND ---------------------- Key Messages for Potential Tropical Cyclone Nine 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 RAINFALL: Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 4 to 8 inches over western Cuba and the Cayman Islands with isolated totals around 12 inches. Over the eastern Yucatan Peninsula, 2 to 4 inches of rain is expected with isolated totals over 6 inches. This rainfall brings a risk of considerable flooding. Over the Southeastern U.S., Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 3 to 6 inches with isolated totals around 10 inches. This rainfall will likely result in areas of locally considerable flash and urban flooding, with minor to isolated moderate river flooding also possible. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone Nine, 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. 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... Ochlockonee River, FL to Chassahowitzka, FL...10-15 ft Chassahowitzka, FL to Anclote River, FL...6-10 ft Indian Pass, FL to Ochlockonee River, FL...5-10 ft Anclote River, FL to Middle of Longboat Key, FL...5-8 ft Tampa Bay...5-8 ft Middle of Longboat Key, FL to Englewood, FL...4-7 ft Englewood, FL to Bonita Beach, FL...3-5 ft Charlotte Harbor...3-5 ft 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. Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the southern coast of Pinar del Rio, Cuba, including the Isle of Youth. Storm surge could raise water levels by as much as 2 to 4 feet above ground level in areas of onshore winds within the warning area along the east coast of the Yucatan Peninsula. WIND: Hurricane conditions are possible within the watch areas in Cuba and Mexico by early Wednesday. Hurricane conditions are possible within the U.S. watch areas late Wednesday and early Thursday. Tropical storm conditions are expected in the warning areas in Cuba and Mexico beginning later today. Tropical storm conditions are possible in the watch area beginning on Wednesday in southern Florida and the Keys, and Thursday in the Florida Panhandle. SURF: Swells generated by the system will affect the southern coast of Cuba and the Yucatan Peninsula of Mexico during the next couple of days. Swells will spread northward toward the west coast of Florida and the northeastern Gulf Coast on Wednesday and Thursday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 to 36 hours. 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 along the northeastern Gulf Coast, including the Florida Panhandle and the Florida west coast, should monitor the progress of this system. Additional watches or warnings will likely be required today. 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 200 AM EDT (0600 UTC), the disturbance was centered near latitude 18.6 North, longitude 82.8 West. The system is moving toward the northwest near 6 mph (9 km/h). This general motion is expected later today and tonight, followed by a faster northward to north-northeastward motion on Wednesday and Thursday. On the forecast track, the center of the system is forecast to move across the northwestern Caribbean Sea through tonight, and then over the eastern Gulf of Mexico on Wednesday and Thursday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is expected during the next few days, and the system is forecast to become a hurricane on Wednesday and continue strengthening on Thursday as it moves across the eastern Gulf of Mexico. * Formation chance through 48 hours...high...near 100 percent. * Formation chance through 7 days...high...near 100 percent. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key Messages for Potential Tropical Cyclone Nine 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 RAINFALL: Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 4 to 8 inches over western Cuba and the Cayman Islands with isolated totals around 12 inches. Over the eastern Yucatan Peninsula, 2 to 4 inches of rain is expected with isolated totals over 6 inches. This rainfall brings a risk of considerable flooding. Over the Southeastern U.S., Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 3 to 6 inches with isolated totals around 10 inches. This rainfall will likely result in areas of locally considerable flash and urban flooding, with minor to isolated moderate river flooding also possible. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone Nine, 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. 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... Bonita Beach to Flamingo...2-4 ft Dry Tortugas...1-3 ft Florida Keys...1-3 ft Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the southern coast of Pinar del Rio, Cuba, including the Isle of Youth. Storm surge could raise water levels by as much as 2 to 4 feet above ground level in areas of onshore winds within the warning area along the east coast of the Yucatan Peninsula. WIND: Hurricane conditions are possible within the watch areas in Cuba and Mexico by early Wednesday. Tropical storm conditions are expected in the warning areas in Cuba and Mexico beginning later today. Tropical storm conditions are possible in the watch area beginning on Wednesday. SURF: Swells generated by the system will affect the southern coast of Cuba and the Yucatan Peninsula of Mexico during the next couple of days. Swells will spread northward toward the west coast of Florida and the northeastern Gulf Coast on Wednesday and Thursday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Issued at 1100 PM EDT Mon Sep 23 2024 967 WTNT44 KNHC 240239 TCDAT4 Potential Tropical Cyclone Nine Discussion Number 3 NWS National Hurricane Center Miami FL AL092024 1100 PM EDT Mon Sep 23 2024 Satellite imagery indicates that there has been little change in the organization of the system since earlier today. Most of the deep convection is over the eastern part of the broad circulation. Animation of proxy-vis GOES images, and radar observations from Grand Cayman Weather Service suggest that the disturbance still does not have a well-defined center of circulation, so the system is kept as a potential tropical cyclone for the time being. The advisory intensity is held at 30 kt which is in agreement with a Dvorak estimate from TAFB. An Air Force reconnaissance aircraft is scheduled to investigate the area in a few hours to provide a better description of the system's structure along with an updated intensity estimate. The initial motion estimate is a rather uncertain 330/5 kt. During the next day or so, the disturbance is expected to turn northwestward along the southern and southwestern side of a mid-level high pressure area. Then, the high is expected to shift eastward while a mid-level trough drops into the central United States. This evolution of the steering pattern should cause the system to accelerate northward to north-northeastward over the eastern Gulf of Mexico and toward the northeastern Gulf Coast through Thursday. There is good agreement in the track guidance, and the official forecast is close to the corrected dynamical consensus model, HCCA, prediction. This is also very similar to the previous NHC forecast. An upper-level low over the northeastern Yucatan Peninsula has been imparting some southwesterly vertical wind shear over the disturbance. This has probably caused a temporary disruption in development. Dynamical guidance shows this low weakening with time, resulting in a reduction of shear in an environment that is otherwise very conducive for intensification. The system is projected to move over waters of very high ocean heat content, which should lead to considerable strengthening during the forecast period. The official intensity forecast is similar to the previous one and lies between the statistical-dynamical model guidance and the purely dynamical model predictions. It should be noted that the 72-hour forecast allows for a little weakening after moving inland, so the cyclone is still expected to be at major hurricane strength at landfall. It should also be noted that the cyclone is expected to grow in size while it traverses the Gulf. Thus, the storm surge, wind, and rainfall impacts will extend well away from the center, particularly to the east of the system. In addition, the fast forward speed while it crosses the coast will likely result in farther inland penetration of strong winds over parts of the southeastern United States after landfall. KEY MESSAGES: 1. The disturbance is forecast to intensify and be near hurricane strength when it reaches the far northwestern Caribbean Sea Tuesday night. Tropical storm conditions are expected over portions of western Cuba and the northeastern coast of the Yucatan Peninsula with hurricane conditions possible. 2. The system is expected to intensify into a major hurricane before it approaches the northeastern Gulf Coast on Thursday. While it is too soon to pinpoint the exact location and magnitude of impacts, the potential for life-threatening storm surge and damaging hurricane-force winds along the coast of the Florida Panhandle and the Florida west coast is increasing. Hurricane Watches and additional Storm Surge watches will likely be issued for a portion of that area Tuesday morning, and residents should ensure they have their hurricane plan in place. 3. Potential Tropical Cyclone Nine will bring heavy rain to portions of the western Caribbean, which will cause considerable flooding and mudslides across western Cuba. Heavy rainfall will likely result in locally considerable flash and urban flooding across portions of Florida, with isolated flash and urban flooding possible across the Southeast, Southern Appalachians, and the Tennessee Valley Wednesday through Friday. Minor to isolated moderate river flooding will be possible.
