If there's no safe building in sight, don't head for the nearest tree, unless it's one of a number of trees grouped together. Lightning strikes the tallest object in the area, so if you hide under a single tree, you're putting yourself in the place most likely to be struck by lightning. You're also safe inside a car. Even if the outside is metal, the inside is safe. If you're in the water, whether on a boat in a lake or swimming in a pool, head to shore when clouds look threatening.
Water also attracts lightning.
If you're around someone who's been struck by lightning, doctors at UT Southwestern Medical Center say you should call for medical assistance immediately. You may also need to treat the victim for shock. Keep the patient lying down, and cover with a blanket or jacket.
