SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Alabama/Florida border to Ochlockonee Florida A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests along the northern coast of the Gulf of Mexico from Alabama to the central Florida Panhandle should monitor the progress of the remnants of Fred. A Tropical Storm Warning will likely be required for portions of the Tropical Storm Watch area later this morning. 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 500 AM EDT (0900 UTC), the remnants of Fred were located near latitude 24.4 North, longitude 84.6 West. The remnants are moving toward the north-northwest near 8 mph (13 km/h) and this general motion is expected to continue through tonight, with a turn toward the north expected on Monday. On the forecast track, the system will cross the southeastern Gulf of Mexico today, cross the east-central and northern Gulf of Mexico tonight and Monday, and move inland along the northern Gulf coast Monday night or early Tuesday morning. Surface observations indicate that maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Fred is expected to re-develop into a tropical storm later today, with gradual strengthening expected while it moves over the Gulf of Mexico until it makes landfall. * Formation chance through 48 hours...high...90 percent. * Formation chance through 5 days...high...90 percent. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure based on nearby surface observations is 1011 mb (29.86 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: The system is expected to produce the following rainfall amounts: Through Monday Keys and southern Florida... 3 to 5 inches with isolated storm totals of 8 inches are 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: A storm surge will raise water levels above normal tide by as much as the following amounts in areas of onshore flow... Mouth of the Pearl River, LA to Suwannee River, FL including Mobile Bay, Pensacola Bay, Choctawhatchee Bay and Saint Andrew Bay... 1-3 ft 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 possible within the watch area by late Monday night or Tuesday morning. SURF: Swells generated by Fred or its remnants are expected to spread across the Florida Keys later this morning and 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 complete advisory at 1100 AM EDT. $$ Forecaster Stewart
