LIGHTNING!
What You Need to Know
• NO PLACE outside is safe when thunderstorms are in the area!
• If you can hear thunder, you are close enough to a storm to be in danger of being struck by lightning. Lightning can travel 10 to 12 miles from a thunderstorm.
• When you hear thunder, immediately move to a safe shelter: a substantial building with electricity or plumbing or an enclosed, metal-topped vehicle with windows up.
