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.
