More rain possible in deluged Midwest as flooding kills 2, causes water to surge around dam

More storms are possible in parts of the deluged Midwest, where flooding after days of heavy rains has killed at least two people, sent a river surging around a dam and forced evacuations and rescues.

Severe storms were forecast for Tuesday afternoon and evening with large hail, damaging winds and even a brief tornado or two in parts of western Iowa and eastern Nebraska, according to the National Weather Service. Showers and storms are also possible in parts of South Dakota and Minnesota, the agency said.

Flooding in those states has also come during a vast and stubborn heat wave. Some communities hit by flooding were under an excessive heat warning Monday with temperatures approaching 100 degrees Fahrenheit (38 Celsius). Dangerous hot, muggy weather was expected again Tuesday around the Omaha area.

More than 3 million people live in areas touched by flooding, from Omaha, Nebraska, to St. Paul, Minnesota. Storms dumped huge amounts of rain from Thursday through Saturday, with as much as 18 inches (46 centimeters) falling south of Sioux Falls, South Dakota, according to the National Weather Service.

Places that didn’t get as much rain had to contend with the extra water moving downstream. Many streams, especially with additional rainfall, may not crest until later this week as the floodwaters slowly drain down a web of rivers to the Missouri and Mississippi. The Missouri will crest at Omaha on Thursday, said Kevin Low, a weather service hydrologist.

On Saturday, an Illinois man died while trying to drive around a barricade in Spencer, Iowa, Sioux City’s KTIV-TV reported Monday. The Little Sioux River swept his truck away, the Clay County Sheriff’s Office said. Officials recovered his body Monday.
