Last message to his mother before tornado hit him

College senior Jeffrey Hunter was hiding in his bathroom in Vilonia when he had his last message exchange with his  mom Regina Wood, who was 20 miles away.

The deadliest Tornado happened in 1925. It swept through three states and killed 689 people and injured 2,000.

Rescue workers have compared the destruction left behind by a tornado to a bomb blast.

They usually occur in the afternoon, but can occur at night.
If you wake up to hear sirens, check the weather station, 
then hide.
