Flooding, which sometimes can happen quickly, will be likely in parts of the northern Gulf Coast states into the Tennessee Valley through Friday.
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.
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.
In all, an additional 1-3″ of rainfall is forecast for parts of Mississippi, Tennessee and Alabama. Isolated total rainfall amounts of 3-6″ will be possible across these states.
A flash flood watch has been issued for parts of the Tennessee Valley area for one to four inches of rainfall and possible flooding into Friday.
The good news is weather conditions should start to dry out through next week, with a chance of showers again this weekend and Wednesday.
