CEDAR RAPIDS, Iowa (AP) — The Cedar Rapids school district has cancelled classes for three days and closed its offices because of the flooding expected in Iowa’s second largest city. The district said Sunday that no classes will be held through Wednesday. The flooding along the Cedar River is expected to reach its peak on Tuesday, but it may take several days for the water to recede. District officials will reevaluate the situation by Wednesday afternoon.

The National Weather Service has revised its forecast for the Cedar River near Iowa’s second-largest city of Cedar Rapids. The river is expected to crest there on Tuesday morning at 23 feet. That level will cause significant flooding in Cedar Rapids, but it has been reduced since earlier forecasts for a crest above 25 feet. But officials are preparing for the worst flooding since 2008.
