Heavy rain could cause minor flooding in Louisiana and Mississippi. #RiverFlooding #LAwx #MSwx

The Mississippi River saltwater wedge is a natural phenomenon exacerbated by drought. The intrusion is possible because much of the Mississippi River's channel in South Louisiana is below sea level. The riverbed is below the Gulf's water surface level up to near Natchez, MS.

Flood crest travel time on the Mississippi River is dependent on highly variable factors such as the current volume of water, recent rainfall across the massive basin, and the specific river stage at various points along the river.

Potential for Drought Improvement

Widespread much-below normal streamflow levels continue over nearly the entire Lower Mississippi Valley region.
