The federal government says up to 27 levees along the Mississippi River could overflow in the coming days, and already one of them has.
A levee breach in Gulfport, Illinois, has closed a bridge connecting it to Burlington, Iowa, Tuesday.
Most communities near the water in southeastern Iowa have already been sandbagging levees, and in some cases pumping water out of basements as it starts to flood in certain areas. The Mississippi is expected to crest in the Burlington area later this evening, though it's already over 10 feet above flood stage.
Through much of central Iowa, attention is turning mainly toward cleanup efforts today. The remaining floodwater has the potential to make people sick as sewage mixes with fuel, farm chemicals and anything else the water picks up.
