(Radio Iowa) – Severe weather caused power outages and property damage in northeast Iowa this weekend. According to Winneshiek County Emergency Management, the city of Calmar was especially hit hard, including the Northeast Iowa Community College campus. Homes, buildings and cars were damaged. In Decorah, a popular trail that runs along the Upper Iowa River was closed due to flooding and storm damage.

The National Weather Service office in La Crosse reports a line of storms that swept through northeast Iowa Saturday night and Sunday morning produced strong winds and heavy rain in Winneshiek and Allamakee Counties. Some buildings were damaged in Waukon and there was significant tree damage reported around Waukon’s City Park.

Many residents of northeast Iowa spent Sunday cleaning up after a round of severe weather swept through the area Saturday night into Sunday morning. At the height of the storm, about 12-thousand customers had lost power. Sean Snyder, Emergency Management Coordinator in Winneshiek County, said  “A lot of tree damage, a lot of downed power lines.”

“The City of Calmar was the hardest hit,” Snyder says. “NICC, South Winneshiek School District was hit as well as the residents of Calmar.” Snyder says there was structural damage to the Northeast Iowa Community College campus in Calmar. The Fidelity Bank will be closed today (Monday) due because of damage to the building on Calmar’s Main Street. Todd Shea with the National Weather Service office in La Crosse, Wisconsin, says their initial assessment is the damage in Calmar was caused by straight line winds.

“From what it appears from surveying and talking to officials in the area, we had just kind of a downburst or a swath of very intense thunderstorm winds that rolled through mainly the western and southern ends of the community,” Shea says. Calmar received three inches of rain as well. Nearly four inches fell in Decorah and storm damage closed a 13-mile bike trail around Decorah. In Allamakee County, a 60 mile an hour wind gust was recorded in Waukon and the Waukon City Park and Campground were damaged.
