When traveling by car seek shelter under an overpass. The number one priority in tornado safety right now is to discourage people from seeking shelter under overpasses. Wind currents are concentrated as they are squeezed under the overpasses and are increased in speed.
Mobile homes attract tornadoes.
Tornadoes have been observed crossing the Appalachian Mts. We should open windows if a tornado is approaching. The southwest corner of the house is the safest location during a tornado. Always go to the lowest level and center of house during a warning. A small interior room like a bathroom is structurally the strongest.
