More than 100 water rescues were required in and around Washington, D.C., on Monday, including 15 people saved from vehicles trapped by high water.

Flash flooding also was reported Tuesday morning in south-central Nebraska, some parts of which just saw 9 inches of rain. Areas of North Dakota received up to 5 inches of rain overnight, also producing flash flooding.

More flooding is possible later on Tuesday as a new system moves through the Plains and western Great Lakes. The most severe storms are likely to be in Wyoming, South Dakota and Nebraska, all of which could see damaging winds, hail or an isolated tornado.
