"The tornado hit across the street from the hospital -- really just one block away -- and there is stuff and debris everywhere," said JoAnn Hettinger, director of patient care at Avera Weskota Memorial Hospital. Her facility received one patient, she said.
In all, 11 homes and three businesses were damaged, according to Roger Dwyer, the Jerauld County emergency management director.
