The deadly tornadoes have killed at least 18 people, ripping homes from their foundations and tossing cars like tinker toys. One of the worst hit areas was Vilonia, a small town in Arkansas. See raw footage of the tornadoes moving in and the destruction it left behind.

The Weather Channel says the tornado touched down Sunday night near Little Rock, Arkansas.
