Lightning

When you're out hiking, you're at the mercy of nature for everything you didn't properly prepare for and for every little curveball thrown your way. Sudden storms, wild animals, rock slides, and flash floods are all examples of surprises that may pop up with little or no warning. You need to have a plan to deal with the most probable challenges and then good sense and skills to deal with anything else.

Lightning is one such surprise that you may experience. I love lightning! It is sooo cool to see the power of nature in such an intense instance of energy. Thunderheads in the far distance with bolts of lightning striking under them are an amazing site. Knowing when to enjoy the show and when to seek shelter is the difference between fun and misery.

Lightning Safety

Keeping an eye and ear tuned to possible lightning is important. You can determine the threat of lightning:

• Check weather reports before starting a hike. If storms are expected, be more vigilant. If nothing but blue skies are expected, relax a bit.
• Understand the general weather patterns for the area and season. In mountains, storms typically form in the afternoon so plan an early morning hike with the ability to get off the mountain quickly after lunch.
• Watch the horizon for cloud formation. Scan the horizon every 15 minutes or so and notice any clouds building.
• Watch distant clouds for lightning. If a cloud looks ominous or you see flashes, have your escape or safety plan ready and make sure everyone in your group understands it.
• Listen for thunder. Depending on wind, terrain, and distance, you may not hear thunder until lightning is already dangerously close. If you do hear thunder, you should be at or on your way to shelter.
• Determine the distance of lightning. If you see a lightning flash, count the seconds until you hear thunder. Divide the number of seconds by 5 to approximate the distance in miles.

30/30 Rule

Avoiding Lightning Strikes

Assuming you are on a hike away from buildings when a lightning storm catches up with you, use these lightning safety guidelines:

• Do NOT seek shelter under a picnic shelter, lone tree, or other object to keep you dry. It will attract lightning. The rain won't kill you so its better to be wet and alive than dry and dead.
• Come down from high places. Seek a valley or depression in the terrain. Be careful of entering a drywash that may channel a flashflood from the rainstorm.
• Seek shelter in a low stand of trees. This will help keep you dry and not attract lightning.
• If you are above treeline, seek shelter in the lowest area you can reach, preferably with large boulders around so you can get some protection from driving rain behind some smaller boulders.
• Put on your raingear and remove your backpack.
• If you have a metal frame pack, leave it 100 feet from where you are seeking shelter.
• If you have a hiking stick or poles, leave them with your pack.
• Your group should not huddle together. Instead, have each person find shelter about 100 feet apart. This minimizes the possibility of multiple casualties from a single strike.
• If you are not able to get to any shelter, you need to become a small target and cross your fingers. Minimize your contact with the ground and minimize your height. Crouching down on the balls of your feet placed close together with your head tucked down is the recommended position. This position reduces your exposure and encourages any lightning strike to travel down your back and hopefully have less damage to vital organs. Lightning travels through the ground from the point of impact in random tendrils similar to tree roots. The smaller your footprint, the less chance there is of you being shocked from a nearby strike.
• Cover your ears and close your eyes to protect from the intense noise and light of nearby strikes.

Lightning First Aid

• Immediately after a close strike, do a headcount of everyone in your party having them call back to you that they are ok. If someone does not respond, go to their location. Only allow those you need to gather. Keep everyone else spread out since there is still danger of additional strikes.
• There is no electrical residue after a strike. It is safe to touch someone that has been struck.
• If there are multiple victims, prioritize care needed. A victim that is not breathing is highest priority. There is a relatively good chance of reviving a lightning victim with CPR.
• Check for and give first aid for burns. Check around jewelry, buckles, and fingers and toes especially.
• Treat for shock, keeping the victim warm and calm.
