Further strengthening is possible over the western Atlantic Ocean through early Tuesday. Claudette is expected to become a post-tropical cyclone by late Tuesday. The estimated minimum central pressure from surface observations is 1007 mb (29.74 inches).

RAINFALL: Claudette is expected to produce additional rainfall totals of 1 to 3 inches with isolated maximum amounts of 6 inches across Alabama, the Florida Panhandle, northern and central Georgia, and Upstate South Carolina through the morning hours. As the system tracks north and east, bands of heavy rain will occur across portions of central and southern Georgia, central and coastal South Carolina into eastern North Carolina through Monday morning resulting in rainfall totals of 2 to 4 inches with isolated maximum amounts of 8 inches. Considerable flash, urban and small stream flooding impacts, as well as new and renewed minor to isolated moderate river flooding are possible across these areas. Storm total rainfall of 5 to 10 inches with isolated 15 inch amounts was observed in southeast Louisiana, southern Mississippi, southern Alabama, and the western Florida panhandle.

NC/VA Border to Cape Lookout, NC...1-3 ft Cape Lookout, NC to Little River Inlet, SC...1-2 ft Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
