Tropical Storm Debby Discussion Number 9 NWS National Hurricane Center Miami FL AL042024 1100 AM EDT Sun Aug 04 2024 Hurricane Hunter aircraft observations indicate that Debby continues to intensify over the eastern Gulf of Mexico. Satellite imagery shows that the cloud pattern is becoming better developed with increasing deep convection near the center of circulation, and WSR-88D radar data indicate that an eyewall is beginning to form. The current intensity estimate is estimated to be 55 kt based on a significant drop in central pressure reported the aircraft. The cyclone has been turning gradually to the right and the initial motion is north-northwestward or 330/11 kt. Over the next day or so, Debby should move through a weakness in the mid-level subtropical ridge over the southeastern United States and reach the northeast Gulf of Mexico coast in the Florida Big Bend region on Monday. After the system makes landfall, the steering currents are likely to weaken as a trough over the northeastern U.S. moves eastward from the area, which should result in a decrease in forward speed. There is significant uncertainty in the track of Debby in the 2-5 day time frame. Much of the track guidance keeps the center over the southeastern U.S. for the next several days as a ridge builds in over the Carolinas. The official track forecast is similar to the previous one and close to the HFIP corrected consensus prediction. This keeps the slow-moving center near the Georgia and South Carolina coast in the 3 to 5 day time-frame. Debby will be moving over very warm waters and in a low-vertical shear environment prior to landfall. Therefore significant strengthening is likely through tonight, especially if the cyclone forms a well-defined inner core The official forecast is near the high side of the objective guidance and calls for the system to become a hurricane within 12 hours. The cyclone will weaken after it moves inland, but since the system will not be far from the coastline for the next few days, it is not predicted to fall below tropical storm strength through 72 hours. Key Messages: 1. Heavy rainfall will likely result in considerable flooding impacts from the Florida Big Bend region through southeast GA and the Coastal Plain of the Carolinas through Friday. Potentially historic heavy rainfall across southeast Georgia and South Carolina through Friday morning may result in areas of catastrophic flooding. Significant river flooding is also expected. 2. There is a danger of life-threatening storm surge along portions of the Gulf Coast of Florida, with 6 to 10 feet of inundation above ground level expected somewhere between Ochlockonee River and Suwannee River on Monday. Residents in the Storm Surge Warning area should follow any advice given by local officials. 3. Hurricane conditions are expected Monday along portions of the Florida Big Bend region where a Hurricane Warning is in effect, with tropical storm conditions beginning this evening. Tropical storm conditions are expected through Monday farther south within the Tropical Storm Warning along Florida's west coast, including the Tampa Bay area. 4. Impacts from storm surge and strong winds are possible along the southeast coast from Georgia to North Carolina through the middle of the week, and storm surge watches and tropical storm watches have been issued for portions of these areas. Additional watches and warnings will likely be required later today.

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 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. 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 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. Interests elsewhere in Florida and the southeastern coast of the United States should monitor the progress of this system. Additional watches and warnings will likely be required later today. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.
