The Mississippi River crest is slowly moving south, with the river expected to crest at Vicksburg, Mississippi, and Baton Rouge, Louisiana this week. New Orleans has crested and is expected to remain at near the current level for the next two weeks, according to National Weather Service.
Excessive rainfall in the Middle Mississippi River Valley over the past couple of weeks has produced major to record flooding along much of the lower Mississippi River, flooding 3 million acres of farmland in Mississippi, Tennessee and Arkansas and evoking comparisons to historic floods in 1927 and 1937.
In addition, the opening of the Morganza Spillway will produce significant flooding over portions of the Atchafalaya River basin.
This flood event is expected to last several more weeks and may be affected or influenced by additional rain events prior to significant lowering of water levels.
