A slow-moving weather system meandering its way over the central Gulf Coast is pulling in warm, moist air from the Gulf of Mexico into the southeastern United States.

This setup is expected to fuel intense downpours of widespread showers and thunderstorms from Alabama to the Carolinas and up through Virginia and West Virginia until Wednesday morning.

The National Weather Service said those areas were under a slight risk that excessive rainfall would lead to flash flooding through Wednesday.

A broader area under a marginal Level 1 risk includes parts of the Tennessee Valley, Central Florida and the southern Appalachian foothills.

The heaviest rainfall was expected over northern Florida and southern Georgia on Sunday, where rainfall rates between 2 and 3 inches per hour were expected.

With the ground already saturated from recent storms, flash flooding remains a risk. Flooding is also a concern for parts of Alabama, northern Mississippi and the Carolinas.
