The National Weather Service has lowered the projected Mississippi River crest by six inches to 58.5 feet at Natchez, Concordia Homeland Security Director Guy Murray said Tuesday.
The crest date is June 13.
“This is mainly due to the breaches in back water levees in Arkansas and Missouri that happened over the past week,” he said. “These breaches are allowing normally protected areas to act as spillways and or storage. This lower projected crest has also pushed the opening of the Morganza Spillway to this Sunday the 9th instead of the 6th like before.”
Murray said the National Weather Service is monitoring a developing system that “will potentially dump several inches of rain above us, which depending on where the rainfall occurs, could eventually revise this river forecast yet again.”
The Mississippi has now been above flood stage for 152 days as of today.
“The longest the river has ever been recorded to be at or above flood stage is 90 consecutive days in 1973, 77 days in 1927, and 53 days in 2011,” Murray said.
He said he and local officials are “staying in contact with GOHSEP, the Corps of Engineers, and the National Weather Service to get the latest and most accurate information possible. Lots of eyes on the river now and will be for the immediate future.”
