Lightning Safety Awareness

"Lightning injures 540 people annually"


June, July, and August are the peak months for lightning-related fatalities in the United States and injures more people annually than Tornadoes and Hurricanes combined.

Are your prepared? Enjoy your summer, but keep these Lightning Safety tips in mind:

  • If you can hear thunder, you are close enough to get struck. Lightning bolts can strike up to 10-miles from the base of a thunderstorm.
  • Many lightning injuries occur when people leave shelter too soon after a thunderstorm has passed. Avoid tragedy and wait at least 30 minutes after the last lightning strike before resuming outdoor activities.
  • Lightning follows the path of least resistance. If you cannot find indoor shelter, stay low to the ground and away from tall objects (like trees). Your vehicle is usually the safest choice if stranded outdoors.
