DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Tropical Storm Fred was located near latitude 26.2 North, longitude 85.2 West. Fred is moving toward the north-northwest near 12 mph (19 km/h), and this motion should continue through tonight. A turn toward the north is expected on Monday. On the forecast track, the center of Fred should move across the eastern and northern Gulf of Mexico through Monday, then make landfall in the western Florida Panhandle Monday afternoon or Monday night. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual strengthening is expected until landfall, while Fred is expected to weaken quickly after moving inland. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The latest minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 1007 mb (29.74 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 Monday... Florida Keys and southern Florida... 3 to 5 inches of rain is anticipated. Through Tuesday... The Florida Big Bend and Panhandle... 4 to 8 inches with isolated maximum storm totals of 12 inches are expected. South-Central and Southeast Alabama through Georgia and the Western Carolinas... 3 to 6 inches with isolated maximum storm totals of 9 inches are expected due to the combination of Fred and a preceding frontal boundary. Heavy rainfall across portions of Florida, southern Alabama, portions of Georgia, and the western Carolinas could lead to areal, urban, small stream and river flooding impacts. 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...2-4 ft AL/FL border to Indian Pass including Pensacola Bay, Choctawhatchee Bay and Saint Andrew Bay...1-3 ft Steinhatchee River to Chassahowitzka, 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 are expected in the tropical storm warning area beginning on Monday. SURF: Swells generated by Fred are expected to reach the coasts of Mississippi, Alabama and the Florida Panhandle on Monday, and could causing life-threatening surf and rip current conditions. Please consult products from your local weather office for more details. TORNADOES: A tornado or two will be possible today into early Monday near the west coast of Florida and the coastal Florida Panhandle.
