DES MOINES — A storm spotter remains hospitalized in Sioux City after lightning struck him as storms moved across several Midwest states Sunday night leaving power outages, trees down and campers overturned.

Hardest hit in Iowa was the Denison area, where Crawford County Emergency Management Director Gregory Miller said five travel trailers were overturned at Yellow Smoke Park. No injuries were reported.

Miller said winds of at least 70 miles an hour knocked down trees and blew down outbuildings on two farms.

Denison and areas to the south saw flash flooding from heavy rain.

In Nebraska, Omaha officials rescued eight people from the fast-moving Elkhorn River and some buildings were damaged by strong winds.

In Kansas City, the Indians-Royals game was suspended due to rain.
