Severe thunderstorms brought severe flooding and a tornado to the Midwest.

Storm winds tossed a school bus onto a building, destroyed or damaged dozens of homes, and cut off power to thousands of customers in Indiana and Illinois.

Footage from WTHR-TV in Indianapolis showed a school bus lying atop a flattened building in Fayetteville, about 70 miles south of Indianapolis, where the tornado was reported.

The sheriff said at least 19 houses were damaged, including three that were leveled.

A trained weather spotter confirmed that a tornado touched down in Sunman, Ind., Sunday afternoon.

"We saw the funnel cloud taking shape," said Capt. Dan Eckstein, of the Sunman Fire Department. "Eventually a small rope cloud came out."

He told TV station WLWT that the twister took the roof off of at least one home, knocking around everything inside. The owners of the home spent much of the evening trying to salvage what they could.

Megan Miller said she ducked as she saw the tornado rip through her neighbor's property.

"I looked out the window and it had come across the field and those trees were laying down and it just started moving around," she said.

Randi Hornberger described how she managed to keep herself and her kids safe.

"It was so surreal. My kids were like, 'Where do we go?' 'Get in the bathtub. Get in the bathtub' you know. 'Just hide, we're gonna hide from the tornado,'" she said.

An Illinois official said at least seven houses were destroyed near Loami, Ill., and 30 more sustained severe damage. He said two horses on a farm were "lost" in the storm.

Officials said winds tore the roofs off buildings in northern Indiana and central Illinois.

Rains from the weather system pounded Iowa, bringing flooding along two eastern Iowa rivers and had local and county officials preparing for the worst.

The major floods of last summer left a lasting impression on the eastern part of the state, one its residents are not eager to repeat.

But as a weekend of steady drizzle turns into major flooding along the Iowa and English rivers, Louisa County Emergency Management Coordinator Staci Griffin said emergency responders are "in limbo."

"There's definitely the potential for some major impacts," Griffin said.
