After doing what they could to prepare, Memphis, Tenn. residents on Monday watched as the Mississippi River swelled to the highest level since 1937.
The river level stood at 47.8 feet Monday evening -- about 14 feet above flood stage -- and was expected to crest at 48 feet, a forecaster for the National Weather Service in Memphis, Ryan Husted, told CNN.
As of Monday, the river had forced about 400 people from their homes, and President Obama had signed a disaster declaration for the state of Tennessee.
Relief organizations have been working tirelessly to help residents prepare for and recover from the effects of the flood. Find out how you can help.
As the American Red Cross continues to assist tornado victims in the storm-ravaged south, it's also preparing to launch a shelter and feeding operation for people living along the Mississippi River. More than 400 Red Cross workers are already in Memphis, supporting efforts there and in nearby communities. It's also sending in leadership teams, disaster workers and thousands of cots, blankets and other relief supplies.
