SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * Coast of the Florida Panhandle from from Indian Pass to Steinhatchee River A Tropical Storm Warning is in effect for... * Coast of the Florida Panhandle from Navarre to the Wakulla/ Jefferson County line. A Tropical Storm Watch is in effect for... * Coast of the Florida Panhandle from the Alabama/Florida border to Navarre 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 Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 36 hours. Interests elsewhere along the northern coast of the Gulf of Mexico from Alabama to the eastern Florida Panhandle should monitor the progress of the remnants of Fred. 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 1100 AM EDT (1500 UTC), the center of Tropical Storm Fred was located near latitude 26.1 North, longitude 84.9 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. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that 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 landfall. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The minimum central pressure reported by the Hurricane Hunter aircraft is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for the Remnants of 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 coast of Mississippi, Alabama and the Florida Panhandle on Monday. 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. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM EDT. Next complete advisory at 500 PM EDT. $$ Forecaster Beven
