Most of southeast Louisiana and parts of south Mississippi is under a Flood Watch through this evening. Scattered thunderstorms will likely cause localized areas of flash flooding and rises on rivers and streams.
Another flood watch is now in effect for areas to the east of I-55 including the Northshore, metro New Orleans, and coastal Mississippi from 5 am to 7 pm on Tuesday. Another round of thunderstorms producing heavy rainfall is expected to impact these areas tomorrow. The ground is saturated from recent rains, so any heavy rain will quickly run off and produce additional flash flooding concerns.
Eastern areas of southeast Louisiana are 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!
