If you're outside, in a car or mobile home, go immediately to the lowest level of a nearby strudy building. Sturdy buildings are the safest place to be when tornadoes threaten. Winds from tornadoes can blow large objects, including cars and mobile homes, hundreds of feet away. Tornadoes can change direction quickly and lift up a car or truck, tossing it through the air. Never try to our-drive a tornado.
Mobile homes are particularly vulnerable.
A mobile home can overturn very easily even if precautions have been take to tie down the unit. If there is no building nearby, lie flat in a low spot. Use your arms and hands to protect your head as tornadoes cause debris to be blown at very high speeds. Do not seek shelter under highway overpasses and bridges - weaker structures could be destroyed from the high winds and dangerous flying debris. You will be safer lying flat in a low-lying area where wind and debris can blow above you.
