Lightning Safety Tips for Hikers
Do you know what to do when you're stuck on a mountain during a thunderstorm? With some wild weather predicted this week, review some key lightning safety tips before you hit the trail.
- Before you go, check the weather. There are many excellent weather resources available to hikers. Our favorite is the National Weather Service's mountains forecast page that provides a detailed forecast for hiking destinations (not just towns and cities) throughout Western Washington.
- Pay attention to the weather on your hike, and try to avoid ridges or walking into a storm on a peak summit. If you can hear thunder, then you're already at risk of a lightning strike, and it's time to take action to protect yourself.
- If you're in the open or on a ridge, retreat to a sheltered area. Shallow caves or picnic shelters aren't good enough. Lightning can bounce around and strike you. Enter the forest, but do not choose the tallest tree in a stand of trees for shelter. Avoid water and isolated trees.
- If you cannot find shelter, crouch down with your feet close together. Do not lie down—doing so creates a larger target for lightning. Crouching on your pack does not lessen your chances of being struck.
- If you're in your tent, get out—the poles attract lightning.
- If you're near your vehicle, get in and roll up the windows—but do not touch any metal during the storm.
Make yourself less attractive (to lightning)
- Toss away metal objects (ice axe, trekking poles, tent poles, climbing gear).
- Get off the cell phone. This could attract lightning.
- Hiking partners should stay at least 15 feet away from each other.
