Tornadoes tore through Kansas overnight, leaving two people dead in Chapman and Soldier and causing extensive damage to Kansas State University. At the University in Manhattan, Kansas, storm damage was estimated to exceed $20 million, according to Tom Rawson, the university's vice president for administration and finance. Thursday's classes were canceled.

"The damage on campus is extensive," Rawson said. "Roofs have been damaged or torn off, windows have been blown out in many buildings."

About 30 summer school classes will be taught at temporary locations Friday. Some classrooms in damaged buildings could be functional by Monday, said M. Duane Nellis, provost and senior vice president.

About 15 homes in Manhattan were "leveled" and more than 30 others, as well as some businesses, were seriously damaged, according to a news release from the Riley County Police Department.
