The Tropical Storm Watch along the west coast of Florida has been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * The Florida Keys west of the Seven Mile Bridge to the Dry Tortugas A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 to 36 hours. Interests in Cuba and in the Florida peninsula and Florida Panhandle should monitor the progress of Fred. Watches could be required for portions of the Florida panhandle on Saturday. 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 PM EDT (0300 UTC), the center of Tropical Depression Fred was located near latitude 22.7 North, longitude 80.6 West. The depression is moving toward the west near 12 mph (19 km/h). A west-northwestward motion is expected to begin overnight. A turn toward the northwest is expected on Saturday, and this general motion should continue through early Monday. On the forecast track, Fred is expected to continue moving near the north coast of central Cuba tonight, pass near or west of the lower Florida Keys on Saturday, and move across the eastern Gulf of Mexico Saturday night and Sunday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Little change in strength is expected through early Saturday. After that, slow strengthening is forecast, and Fred could become a tropical storm again by late Saturday or Saturday night. The estimated minimum central pressure is 1013 mb (29.92 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: Portions of Cuba...2 to 5 inches with isolated maximum totals of 8 inches. This rainfall may lead to scattered flash flooding. Across the Bahamas...1 to 3 inches, with isolated maximum totals of 5 inches. Tonight through Monday, 3 to 6 inches of rain is anticipated across the Keys, southern and central Florida north towards the Big Bend, with isolated maximum totals of 8 inches. Heavy rainfall could lead to areal, urban, and small stream flooding impacts, and cause new minor flooding across the western Florida Peninsula and exacerbate ongoing minor to isolated moderate flooding in northern Florida. From Sunday onward, heavy rain and flood impacts could extend into inland portions of the Southeast and into the southern and central Appalachians and Piedmont as Fred interacts with a front in the area. WIND: Tropical storm conditions are expected in portions of the warning area across the Florida Keys on Saturday. SURF: Swells generated by Fred are expected to spread across portions of the Bahamas and the northern coast of Cuba through tonight. These swells could reach the Florida Keys and southern Florida by early Saturday and increase along the west coast of Florida Saturday night and Sunday. Please consult products from your local weather office for more details. TORNADOES: A tornado or two may be possible starting Saturday afternoon across portions of central and southern Florida.
