In high rise buildings, go to interior small rooms or halls. Stay away from exterior walls or glassy areas. Most deaths occur in cars and mobile homes. If you are in either of those locations, leave them and go to a substantial structure or designated tornado shelter. If no suitable structure is nearby, lie flat in the nearest ditch or depression and use your hands to cover your head.
Lightning can strike up to several miles away from the thunderstorm.
Do not take a bath or shower. A pickup truck or hard top automobile with the windows up can also offer fair protection. If you are in a wooded area, seek shelter under a thick growth of relatively small trees. If you feel your hair standing on end, squat with your head between your knees. Avoid isolated trees or other tall objects, bodies of water, sheds, fences, convertible automobiles, tractors and motorcycles.
