Lightning is one of the most erratic and unpredictable characteristics of a thunderstorm, and because of this, no one can guarantee absolute protection. However, knowing and following lightning safety guidelines can greatly reduce the risk of injury or death.

Most lightning victims are not struck during the worst of a thunderstorm but rather before or after the storm reaches its greatest intensity. Because lightning can strike as far as 25 miles away from its parent thunderstorm, it can be dangerous even outside the area of rainfall!

Therefore, if you can hear thunder, you are within striking distance. Seek safe shelter immediately. Remember this lightning safety rule: WHEN THUNDER ROARS, GO INDOORS! Stay inside for 30 minutes after the last clap of thunder. Do not wait for the rain to start before you decide to seek shelter, and do not leave shelter just because the rain has ended.

The best way to protect yourself and your family from the dangers of thunderstorms is to be prepared. If you have outdoor plans, familiarize yourself with the latest weather forecast before heading out. Consider taking a portable NOAA weather radio or AM/FM radio with you. Upon arriving to a site, determine where you will seek shelter in the event of a thunderstorm and how long it would take to reach that shelter. A sturdy, enclosed structure with plumbing and electrical wiring is safest, but if one is not available,
most enclosed metal vehicles are safe alternatives.
