WATCH: The Most Shocking Videos of the Oklahoma Tornadoes

As at least four tornadoes ripped through Oklahoma on Sunday evening and night, residents scurried for shelter as the sirens sounded. At least two people have been confirmed dead, according to the AP: Glen Irish, 79, and Billy Hutchinson, 76, both from the town of Shawnee — where the Steelman Estates Mobile Home Park was destroyed.

The twisters were part of a northeastward-moving storm that spanned from Texas to Minnesota. The tornadoes traveled through central Oklahoma, and Governor Mary Fallin declared a state of emergency because of severe storms and flooding, according to Fox News.

And while the storm failed to do major damage in the Oklahoma City suburb of Edmond, a twister touched down there and dropped grapefruit-sized hail.

Tornadoes also touched down in Missouri and in Wichita, Kansas. Golf ball sized hail ripped through homes and broke windows in Kansas.
