The National Weather Service in Mobile said an additional 1 to 3 inches of rain will be possible in those areas today.

North Alabama flash flood watch

A flash flood watch will be in effect for most of north Alabama through this evening.

Three to 4 inches of rain will be possible. And the rain may be heavy: The rainfall rate could possibly exceed 2 inches per hour, the weather service said.

Expect higher rain chances to stick around statewide through at least Wednesday. After that a cold front is expected to make its way into Alabama, which should bring cooler and drier air in its wake, forecasters said.
