In past hurricanes, flooding at dozens of farms also left hundreds of thousands of dead hogs, chickens and other decomposing livestock bobbing in floodwaters.

Stream gauges across the region showed water levels rising steadily, with forecasts calling for rivers to crest Sunday and Monday at or near record levels. The Defense Department said about 13,500 military personnel had been assigned to help relief efforts.
