MEMPHIS, Tenn. — The Shelby County Office or Preparedness has issued a Flood Warning for the Mississippi River.

The department said after almost a full month of rain in the United States, the river is expected to crest at 43.5 feet on January 9.

The warning officially goes into effect on January 2.

Shelby County Mayor Mark Luttrell said Office of Preparedness, the National Weather Service, and the Tennessee Emergency Management Agency have all been, and will continue to be, in contact with one another, giving updates on the situation.

A meeting that included representatives from the NWS, several law enforcement agencies, fire departments, the Office of Preparedness, and other emergency organizations was held on Tuesday.

It was all in an effort to be ready for whatever lies ahead.

“Water is already high near the Loosahatchie and Wolf Rivers and along Nonconnah, Cypress and Big Creeks. Those who work and live near these areas need to be vigilant,” said Dale Lane, Director of the Shelby County Office of Preparedness.

“All City of Memphis bureaus are on alert. We are ready to respond should evacuations be needed,” said Lieutenant Jim Logan, Director of the Memphis Office of Emergency Management.

The Mississippi River is already causing problems for many residents.

In West Alton, Missouri residents were told to evacuate Tuesday after the river started going over the levees there, reported KTVI.

To make matters worse, the river is not expected to crest in that area until a few days from now.

In St. Louis, Mayor Francis Slay has declared an emergency after flood waters began to rise.

Citizens were asked to take time out of their day to help sandbag the levee system.

The city has also closed 36 flood gates along the river and set up patrols to watch for leaks.

Flooding has killed at least 11 people in Missouri and Illinois so far.

A State of Emergency has been issued for Missouri.
