RAINFALL:  Nicholas is expected to produce additional rainfall
amounts of 2 to 5 inches across the central Gulf coast in
southeastern Louisiana, southern Mississippi, southern Alabama and
the Florida Panhandle through Friday, with isolated storm totals of
8 inches possible. Considerable flash flooding impacts, especially 
in urban areas, are possible across these regions.
 
Widespread minor river flooding is expected, while scattered
moderate river flooding is possible, across portions of southeastern
Louisiana, southern Mississippi, southern Alabama, and the Florida
Panhandle.
