Lightning Safety on Trails and at Camp
Thunderstorms build quickly in many mountain areas, often in the afternoon. Weather services are clear that no place outdoors is safe when thunder is heard. The best protection is planning that keeps you off exposed ground when storms are likely.
Planning around storms
Check forecasts for thunderstorm risk, and in areas with regular afternoon storms, plan to reach summits and ridges early and descend before clouds build. Watch the sky through the day for towering, darkening clouds.
If you can hear thunder, you are close enough to be struck.
When a storm approaches
Move off peaks, ridges and open areas toward lower ground, and avoid isolated tall trees, water and metal objects such as fences. A hard-topped vehicle or a substantial building offers real shelter; tents and open shelters do not.
Groups should spread out so that one strike is less likely to injure several people.
If you are caught on open ground with no better option, keep moving toward lower, less exposed terrain rather than waiting in place. Weather services note that crouching does not make you safe outdoors.
Afterward and at camp
Wait about 30 minutes after the last thunder before returning to exposed terrain. Choose campsites away from summits and lone trees during storm season.
Lightning victims do not carry an electrical charge and can be helped immediately. Call for emergency help and start CPR if needed and you are trained.
