About Tornadoes One of the most alarming aspects of these phenomena is their randomness, almost as if they had vindictive personalities. They'll appear suddenly and take out one house here, but leave its neighbors and the houses across the street untouched. Tornadoes are always visible from a great distance. They can be hidden in heavy rainfall.
Tornadoes cause houses to explode from changes in air pressure.
Homes are damaged by strong winds, not air pressure changes. By opening the windows, you can balance the pressure inside and outside your home so a tornado will not do damage. The force of a tornado can rip through a structure, whether the windows are open or not. One should not open the windows when a tornado threatens - this could actually make the situation worse. The best place to be during a tornado is generally in the southwest corner of the basement.
