LAKE CITY, Iowa - More than 100 people were attending an awards ceremony at South Central Calhoun High School Sunday evening when a tornado struck the building.
School officials received an alert warning of the approaching tornado and everyone in the auditorium was able to seek shelter in the school's basement and locker room area just minutes before the tornado struck.

"The lights went off, and everyone's ears kind of popped," South Central Calhoun girls' basketball coach Dave Birks told the Des Moines Register. "They say a tornado sounds like a freight train, and that lasted only 5 or 10 seconds. Everyone came upstairs, and it was a mess."
"Most of the roof of the building was torn off," said Austin Jacobs. Jacobs went into Lake City after the storm struck to examine the damage. "There was debris everywhere."
Jacobs said a second severe storm forced people to seek shelter inside the damaged school building.
No one in the school was seriously injured.
