The National Weather Service says a confirmed tornado has hit a small town in central South Dakota.
Meteorologist Todd Heitkamp says law enforcement in Wessington Springs reported the tornado went right "through the heart of town." It hit just before 8 p.m.
A spokeswoman for the hospital in town says one patient in good condition is being treated as a result of the tornado.
Heitkamp says homes and businesses have been damaged. Multiple calls to the Jerauld County Sheriff's Office rang busy.
Confirmed tornadoes also touched down nearby, outside the towns of Woonsocket and Alpena.
Wessington Springs is about 125 miles northwest of Sioux Falls and has a population of about 1,000.
Gov. Dennis Daugaard tweeted that he deployed 100 South Dakota National Guard soldiers and equipment to Wessington Springs.
