Avoid using electrical appliances. Use phones only in an emergency. Turn off air conditioners. Power surges from lightning can overload the compressors. Do not take a bath or shower.
Water is an electrical conductor.
If lightning is occurring and a shelter is not available, get inside a hard-top vehicle and keep the windows up. If no vehicle is available, find a low spot away from trees, fences and poles. Be alert to the possibility of flash flooding. If you are in the woods, take shelter under short trees or bushes. If you feel your skin tingle or your hair stand on end, squat low to the ground on the balls of your feet.
