Drop everything and get low.

The second you hear thunder, assume lightning is a threat and immediately change your position.

You are the tallest thing in an open area. That’s bad. Lightning wants to hit the highest point, and if that’s you, you lose. Your first move is to get as low as possible without lying flat. Squat down on the balls of your feet, heels together, hands over ears, head tucked. If you have a sleeping pad or dry bag, crouch on that — insulation helps but it’s not a guarantee.

If you’re with others, spread out at least 20 feet apart so if one person gets hit, everyone else can still help. Do not huddle together. Do not stand under a lone tree—that’s the most dangerous place. Do not lie flat on the ground (ground current can travel through you). And for the love of everything, get off any ridge or hilltop immediately.

Wait 30 minutes after the last thunderclap before you resume normal camping. Lightning can strike from a storm that’s already moved past.

This is not the time to look tough. Get small, stay put, and you’ll be fine.
