Emergency officials reported a tornado near Lucien, in northern Oklahoma, severely damaging a house and destroying a barn. One storm cell near Crescent, 32 miles north of Oklahoma City, spawned twin tornadoes.
Meanwhile, shelters have opened in several counties for those having to leave their homes.
