2021-08-17 01:50:22| National Hurricane Center (Atlantic)
Issued at 700 PM CDT Mon Aug 16 2021 000 WTNT31 KNHC 162350 TCPAT1 BULLETIN Tropical Storm Fred Intermediate Advisory Number 29A NWS National Hurricane Center Miami FL AL062021 700 PM CDT Mon Aug 16 2021 ...CENTER OF FRED CONTINUES MOVING INLAND OVER THE EASTERN FLORIDA PANHANDLE... ...HEAVY RAIN AND STORM SURGE THREAT CONTINUES... SUMMARY OF 700 PM CDT...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...30.6N 85.2W ABOUT 15 MI...20 KM S OF MARIANNA FLORIDA MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...NNE OR 20 DEGREES AT 10 MPH...17 KM/H MINIMUM CENTRAL PRESSURE...999 MB...29.50 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * Coast of Florida from Indian Pass to Yankeetown A Tropical Storm Warning is in effect for... * Coast of the Florida Panhandle and Big Bend from the Okaloosa/Walton County line to the Steinhatchee River A Storm Surge Warning means there is a danger of life-threatening inundation from rising water moving inland from the coastline 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 Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. 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. DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Storm Fred was located near latitude 30.6 North, longitude 85.2 West. Fred is moving toward the north-northeast near 10 mph (17 km/h), and this general motion with an increase in forward speed is expected over the next couple of days. On the forecast track, Fred will move from western Georgia on Tuesday across the southern Appalachian Mountains to West Virginia by Wednesday. Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Rapid weakening is expected, and Fred should become a tropical depression by early Tuesday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. A wind gust of 55 mph (89 km/h) was recently reported at Marianna, Florida. A wind gust of 46 mph (74 km/h) was observed at an observing site near Bainbridge, Georgia. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Fred can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC and on the web at www.hurricanes.gov/graphics_at1.shtml?key_messages. RAINFALL: Fred is expected to produce the following rainfall amounts: Through Tuesday... The Florida Big Bend and Panhandle... 4 to 8 inches of rain with isolated maximum storm totals of 12 inches are expected. Southeast Alabama through western and northern Georgia, and the western Carolinas... 4 to 8 inches of rain with isolated maximum storm totals of 10 inches are expected. Through Wednesday... Portions of the Mid-Atlantic States...2 to 4 inches of rain with isolated maximum storm totals of 6 inches expected as Fred interacts with a nearby front. Heavy rainfall across portions of the Southeast and Mid-Atlantic States could lead to flash, urban, small stream and isolated river flooding impacts. An increased risk of landslides exists across the mountains of North Carolina as well as portions of the Blue Ridge Escarpment on Tuesday. 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... Indian Pass to Steinhatchee River...3-5 ft Steinhatchee River to Yankeetown, FL...2-4 ft Okaloosa/Walton County Line, FL to Indian Pass including Choctawhatchee Bay and Saint Andrew Bay... 1-3 ft Yankeetown, FL to Aripeka, FL...1-3 ft The deepest water will occur along the immediate coast near and to the east of the landfall location, where the surge will be accompanied by large 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. WIND: Tropical storm conditions will continue in portions of the Tropical Storm warning area for the next few hours. SURF: Swells generated by Fred are affecting the coasts of Mississippi, Alabama and the Florida Panhandle, and could causing life-threatening surf and rip current conditions. Please consult products from your local weather office for more details. TORNADOES: A few tornadoes are possible this evening and tonight across parts of the Florida Panhandle, southwest Georgia, and southeast Alabama. The tornado threat will shift northward into parts of northeast Georgia, the western Carolinas, and southern Virginia on Tuesday.
