Lightning Safety: Protecting Lives During Thunderstorms

Lightning is one of the most dangerous weather hazards affecting outdoor sports, recreation, construction sites, parks, and community events. Every year, lightning strikes the United States millions of times, causing injuries, fatalities, and millions of dollars in property damage. The greatest danger is that lightning can strike well before rain begins and continue long after a storm appears to have passed.

Understanding Lightning

Lightning is a massive electrical discharge that develops inside thunderstorms. A single bolt can reach temperatures approaching 50,000°F—hotter than the surface of the sun—and carry enough electrical energy to cause severe injury or death.

Contrary to popular belief, lightning does not only strike the tallest object. It can strike the ground, open fields, trees, buildings, athletic fields, and even people.

When Are You at Risk?

If you can hear thunder, you are close enough to be struck by lightning. This simple rule is one of the most important safety guidelines to remember.

Outdoor activities should be suspended immediately when:

Thunder is heard
Lightning is detected nearby
A lightning alert has been issued
Severe thunderstorms are approaching

Safe Shelter

The safest locations include:

Fully enclosed buildings with electrical wiring and plumbing
Hard-topped vehicles with the windows closed

Avoid:

Dugouts
Picnic shelters
Tents
Trees
Open fields
Metal bleachers

The 30-30 Rule

Safety professionals recommend waiting at least 30 minutes after the last clap of thunder before returning to outdoor activities. Lightning frequently strikes behind the main storm.
