MYTHS

1.  Highway overpasses are a safe place to shelter if you are on the road when you see a tornado coming.

        -The truth is anytime you put yourself above ground level during a tornado, you are suicidely putting youself in harms way.
        -Nine out of ten storm chasers would agree that finding shelter under an overpass is seriously dangerous.

2.  Opening windows to equalize air pressure will save a roof, or even a home, from destruction by a tornado.

        -Opening windows is a dangerous and useless waste of time, and actually could be harmful to the house.
        -To get to the very center of mature tornado(where the pressure may be low enough to cause some explosive effects), the  windows would have to endure 100-200mph winds in the walls of the vortex.

3.  Some towns are "protected."

        -The ideas that one's town is "protected" is wishful thinking.
        -One's town is never protected for sure.  The facts may say the tornado has been seen a mile north or south of town ten times in the past ten years, but has never made it through town.  That is just luck, not "protection."
 

4.  The southwest corner of the basement is the safest location during passage of a tornado.

        -The side of the home facing the tornado is the LEAST safest part of the basement.
        -A house is more likely to shift than be completely blown free of the foundation.
