Avera McKennan Hospital and University Health Center in Sioux Falls, S.D. was recently damaged by a tornado, but no injuries were reported, according to an article on the AP website.
Dozens of buildings were damaged or destroyed, trees torn up and power lines downed.
A employee reported that there are big chunks of metal hanging from the building; broken glass everywhere; tree limbs and trash; cars that have been picked up and moved with their windows blown out and there was water pouring in through the ceiling.
Although a significant tornado had not struck Sioux Falls for 25 years, the Avera Health System hospitals have kept up regular preparedness training, the article said.
