A far-reaching outbreak of thunderstorms, some severe, will take place over the South through early Tuesday. One factor of these thunderstorms will be their potential to unleash excessive rainfall of 2, 3 and even 4 inches.

Flooding during the first half of April has already proven to be troublesome along some Southern rivers, mostly over southern Georgia, southern Alabama and northwestern Florida. Among the major river basins to have had moderate to major flooding thus far is the Altamaha of Georgia and the Suwannee of Georgia and Florida. Any widespread rainfall of at least 1-2 inches would aggravate flooding where it is ongoing. It could also spark new flooding in other areas.

Whether or not flood potential to bigger streams is realized, these soaking thunderstorms will lead to urban and small stream flooding.
