Residents of Anderson, Ind., look into a large sinkhole that caved in Tuesday in the wake of recent flooding. Deadly storms dumped rain from the Midwest to New England and knocked out power to thousand of homes across the South. In the tiny Iowa town of Hamburg, the Nishanabotna River has risen about a foot each hour, forcing more than half of the 1,250 residents to leave their homes. National Guard troops quit sandbagging to go door to door, warning people to evacuate. About 200 refused to leave. At least nine people have been killed by violent weather across the eastern half of the country since Sunday.
