Due to heavy rainfall the last few days, several rivers are in minor to moderate flood. River flooding will continue to be a concern through at least midweek with continued heavy rain chances. You can find your river flood forecasts at water.noaa.gov.
Another flood watch is in effect for areas to the east of I-55 including the Northshore, metro New Orleans, and coastal Mississippi through 7PM tonight. Another round of thunderstorms producing heavy rainfall is expected to impact these areas today. 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!
