Changes to American Red Cross Policy Regarding Tornado Safety

If you are caught outdoors, in a mobile home, or in a car when a tornado warning is issued, seek shelter in a basement, tornado shelter or sturdy building. If you cannot get to shelter, the American Red Cross now suggests doing the following.
Get into a vehicle, buckle your seat belt, and try to drive at right angles to the storm movement and out of the path of the tornado.
If strong winds and flying debris occur while you are driving, pull over and park, keeping seat belts on and the engine running. Crouch down below the windows, covering your head with your hands and a blanket if possible.
If you are unable to get to a building or vehicle, as a last resort, lie in a ditch or depression and cover your head with your hands.
Previously the American Red Cross adhered to the National Weather Service’s recommendation that people should lie flat in a ditch or low-lying area.
However, after careful consideration, the Advisory Council for First Aid, Aquatics, Safety and Preparedness (ACFASP), an independent panel of health and safety experts that advise the Red Cross, found no scientific evidence to support this long-held tenant.
