"Hundreds of people were being evacuated from their homes in Missouri after a levee was breached Monday night."

"Officials in St. Charles County near St. Louis activated warning sirens after the levee broke, a statement from the county said.

Earlier Monday, a bridge connecting West Alton, Missouri, and Alton, Illinois, was shutdown after a temporary flood barricade gave way.

Forecasters say there could be major flooding Tuesday. The Mississippi River at St. Louis was 10.1 feet above flood stage Monday night, according to the U.S. Geological Survey website."
