The National Weather Service has received reports of a tornado hitting a small southern South Dakota town.
Meteorologist Philip Schumacher at the service's Sioux Falls office says law enforcement officials said a tornado hit Delmont about 10:45 a.m. Sunday.
Delmont has about 200 residents and is about 90 miles southwest of Sioux Falls.
Schumacher said no deaths have been reported and it wasn't known whether there were injuries. He said a couple buildings have been damaged.
The National Weather Service has issued tornado watches in several Midwest and Great Plains states, running until 9 p.m. Sunday in many places.
Watches have been issued for north and central Texas, eastern Oklahoma, western Arkansas, western Iowa, eastern Nebraska and parts of Minnesota and South Dakota.
