Lightning can strike on the most beautiful of days. It can be brought on by heat, an oncoming thunderstorm or remnants of a storm that fell apart. The only real predictor of lightning is hearing thunder. When you see a lightning storm, take shelter immediately, if possible.
What to do if Caught Outside in a Lightning Storm
Seek shelter when you hear thunder, lightning can strike up to 10 miles from the heart of a thunderstorm. Take cover, preferably in a brick-and-mortar building such as a house, and stay away from all windows and doors. Metal attracts lightning and conducts electricity, so stay away from metal sheds and outbuildings.
Remove any metal objects on your possession, if there are no buildings available for shelter. Sports teams that are often caught in thunder-and-lightning storms remove all shoes or equipment with metal cleats or handles. Stay away from metal bleachers and fences.
Stay away from trees. Though a tall tree may seem like a sturdy structure to take shelter under during a lightning storm, it is one of the worst places to hide.
Get away from water. On or in water is the absolute worst place to be during a lightning storm. Water is a conductor of electricity, so there is no safe place on a lake or pond to hide.
Staying Safe Inside During a Lightning Storm
Stay off of corded telephones, computers and any other electrical equipment in the home.
Stay away from all plumbing outlets in the shelter. Lightning can follow the path of water.
Use surge protectors for all electrical equipment to reduce the chance of fires starting due to lightning strikes.
Install ground fault protectors on all outlets near plumbing fixtures. This should be done in all homes.
