Two people have been killed by strong tornadoes that swept across portions of southern Oklahoma.
Johnston County Sheriff's Sgt. Stacey Pulley says a man died Monday near the town of Connerville. A storm earlier in the day killed a man in a home near Wynnewood.
Some of Monday's weather was so bad that forecasters declared a "tornado emergency" for the towns of Roff and Hickory, which were in the path of a storm.
The Oklahoma Office of Emergency Management reported the storms destroyed a radio station building in Coal County and an undetermined number of homes in Murray, Garvin and Johnston counties.
Tornadoes were also reported in Iowa and Nebraska, but there were no immediate reports there of injuries or significant damage.
