When It Hits

• If you are outside, seek refuge in a car or grounded building when lightning or thunder begins.

• If you are caught outside away from a building or car, stay clear of water bodies and tall objects like trees. Find a low spot or depression and crouch down as low as possible, but don't lie down on the ground. Lightning can move in and along the ground surface, and many victims are struck not by bolts but by this current.

• If you are inside, avoid taking baths or showers and don't wash dishes. Also avoid using landline phones, televisions, and other appliances that conduct electricity.

Once It's Over

• Stay inside for 30 minutes after you last see lightning or hear thunder. People have been struck by lightning from storms centered as far as 10 miles (16 kilometers) away.
