The day following a tornado outbreak that killed two people in Oklahoma, National Weather Service officials examined the damage Tuesday left behind as residents pick up the pieces from Monday's storms. 

As of Tuesday evening, National Weather Service had examined eight tornado tracks. Of the eight tornadoes that touched down Monday, two were given EF-3 ratings. EF-3 damage means the tornadoes had estimated winds of 136 to 165 MPH. The winds from an EF-3 tornado is considered extensive enough to destroy mobile homes and entire stories of well-built homes, lift cars off the ground and uproot trees. 

The two EF-3 tornadoes swept through Wynnewood and Roff in Southern Oklahoma. 

Showing an example of what to do in the midst of a tornado, the National Weather Service tweeted a photo of a boy who remained in his bathroom on the first floor of his home. The boy was home alone, according to the NWS, and survived in the bathroom. The entire home around the bathroom was blown away.
