Another round of heavy rainfall is expected to impact portions of the area today. Recent heavy rainfall in the area, especially for areas east of I-55 in southeast Louisiana and coastal Mississippi has already led to flooding issues. Any additional rainfall in these areas, even light rain, could lead to additional flooding concerns. Given these concerns, a flood watch is in effect from 7 am to 7 pm tomorrow for the entire region. Please stay weather aware today and remember to turn around don't drown if you encounter a water covered road while driving.
All of southeast Louisiana along with southwest and coastal Mississippi is under a Slight Risk of excessive rainfall today. A good portion of the area is also under a marginal risk of excessive rainfall. Scattered storms today will bring intense rainfall rates at times that may bring localized areas of flash flooding. Additional threats include rises on rivers and streams and water covered-roadways. Stay weather aware!
