SPRINGFIELD, Mo. (AP) — Flooding has closed nearly 280 Missouri roads and forced officials to evacuate some campgrounds.

The National Weather Service has issued flood warning and flash flood warnings across a large swath of the state.

The Springfield News-Leader reports that the overnight storms dumped 6 inches or more of rain on many parts of the Ozarks, sending river levels soaring. In the Springfield area, the James River jumped from 5 feet (1.5 meters) in just a few hours. People camping along the river and at Roaring River State Park near Cassville were told to leave.

In eastern Missouri, waters are rising along the Mississippi River. It was expected to crest Friday in Hannibal at the third-highest level on record. Meanwhile, several Missouri River levees are projected to overtop.
