LAKE CITY, Iowa (AP) – People are cleaning up damage after what’s believed to have been a tornado hit Lake City on Sunday. The storm tore the roof from a high school as about 150 students, family and faculty attended an awards ceremony inside. People scrambled into the basement and a locker room just minutes before the storm hit.

Dave Birks, the girls’ basketball coach at South Central Calhoun High School, says the lights went out and everyone’s ears popped.  Birks says school windows were blown out, the high jump pit from the school’s outdoor athletic complex is missing, and hurdles were scattered everywhere.
