Get Underground
If you ever decide to move to an area where tornadoes are prevalent, a great piece of advice to keep you safe at all times is to buy a home with an interior basement. This is because you are underground and the furthest away from the danger of the destruction caused by tornados.
Getting to a strong structured space that will hold up and keep you safe from direct contact with strong winds is your best chance at surviving dangerous winds without harm to your and your family. If you do not have a basement, the next best thing is your closet, bathtub, or hall way. You want to be in a space with no windows.
