Manhattan ? Powerful thunderstorms left thousands of people without electricity across northeastern Kansas and damaged trees and a roof at Kansas State University.

Westar Energy reported more than 22,000 customers without power at one point Friday evening, including nearly 16,000 in Riley County, home of the Kansas State campus. Power was restored quickly.

The National Weather Service says winds gusted up to 93 mph in Manhattan late Friday afternoon as the storms moved through the region. A tractor-trailer was blown over in the city.

Kansas State police Capt. Don Stubbings says the wind caused a significant loss of trees in a small area. He compared it to the tree damage caused by a tornado in June 2008.

There was also damage to the roof on Anderson Hall, the main administration building.
