Alabama Faces Overnight Flash Flood Threat in the North as Isolated Severe Storms Target Southern Counties
ALABAMA — Weather conditions are dividing the state overnight as flooding concerns persist across northern Alabama, while isolated severe thunderstorms may develop in the southern half of the state. Forecasters say the impacts will unfold between midnight and around 8 a.m. Central Time, with different risks depending on location.
Flash Flood Watch Covers Northern Two-Thirds of Alabama
A flash flood watch remains in effect for the northern two-thirds of Alabama overnight, according to the forecast graphic. This includes major population centers such as Birmingham, Huntsville, Tuscaloosa, Anniston, and Gadsden, where repeated rounds of rain could lead to rapid water buildup in low-lying and flood-prone areas.
Officials urge residents in the watch area to remain alert for rising creeks, ponding on roadways, and poor drainage flooding, especially during the overnight hours.
Isolated Severe Storms Possible in Southern Alabama
While flooding is the main concern farther north, southern Alabama could see a few isolated severe thunderstorms late tonight into early morning. Cities including Montgomery, Troy, Dothan, Mobile, and surrounding areas fall within the zone where stronger storms cannot be ruled out.
These storms may bring:
- Brief heavy rainfall
- Strong wind gusts
- Localized lightning activity
Widespread severe weather is not expected, but isolated storms could briefly intensify as they move through the southern half of the state.
