Flood crests rolled down rivers from Oklahoma to New York after forcing hundreds out of their homes. Record flood levels were reached in the wake of heavy rains and unseasonably warm weekend weather that melted thick piles of snow. In some places, ice jams backed up water in swollen rivers. The northern third of Indiana was hard hit by floods, and officials in Fort Wayne expected the Maumee River to crest at about 24 feet. Crews filled and stacked tens of thousands of sandbags against a river expected to reach nearly 10 feet above flood level. High water caused at least four deaths in Indiana, Illinois and Missouri, officials said.
