The Gulf Coast and Tennessee Valley Continues To Get Soaked

25 Mar 2021, 8:00 am

Flooding, which sometimes can happen quickly, will be likely in parts of the northern Gulf Coast states into the Tennessee Valley through Friday.

Recent Rainfall

24-hour observed rainfall accumulation across Louisiana, Mississippi, and Alabama showing 2-6″ of accumulation.

A round of heavy rain and thunderstorms already soaked the northern Gulf Coast cities on Tuesday, March 23rd with several inches of rain. Numerous daily rainfall records were broken, even shattered in some cases.

Record rainfall in Lake Charles, Louisiana on Tuesday, March 23rd, with 4.99″ of rain falling throughout the day.
New Orleans, Louisiana had record rain Tuesday, March 23rd with more than 5.5″ of accumulation!

The corridor of heaviest rainfall was between southeast Louisiana and coastal Mississippi/Alabama. These areas that were already heavily hit by rain will be subject to additional flooding, because the ground is already saturated and any additional rainfall could trigger flooding more easily.

Flood Potential Outlook

Looking ahead, another round of heavy rain will be likely today (Thursday) as a warm front lifts north from the Gulf of Mexico. These heavy showers will have the potential to cause scattered flooding along bayous, creeks, rivers, etc.


Showers and thunderstorms will develop throughout the day from the Gulf Coast states into the Ohio Valley. Heavy rain will be focused in two areas: along a cold front where severe thunderstorms will be possible, and near the low pressure center.

Flood Alerts

The good news is weather conditions should start to dry out through next week, with a chance of showers again this weekend and Wednesday.
