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 pass near or west of the west coast of the Florida peninsula Saturday night and Sunday. Little change in strength is expected tonight. After that,
slow strengthening is forecast, and Fred could become a tropical storm again on Saturday.

Hazards Affecting Land
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.
• Today 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, and potentially worsen ongoing minor to isolated moderate river flooding over 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. Tropical storm conditions are possible in the watch area in Florida beginning 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.
