Thunderstorm Safety While on the Trail


What would you do if you were caught in a thunderstorm while out on the Trail? Last week, thunderstorms rolled through the northern portion of Michigan’s Lower Peninsula wreaking havoc on forests and trails. A couple of our hikers were making their way back to their vehicle in the Fife Lake area and were caught in 3 separate storms:

On Sunday we hiked back to the Jeep through 3 thunderstorms, all included heavy rain and lightning. It cleared up in between the first two storms, but the last kept going beyond when we finished. The wind was extreme, and we were pelted with hail the size of peas and marbles. We huddled under the biggest, strongest tree we could find, a huge white pine. The pine stood tall during the storm while all the other trees bent over from the strong winds.

We were so glad to hear they made it out safely!

You know to always to check the weather before heading out on a hike, but as all who live in the Great Lakes region know, “If you don’t like the weather, check back in five minutes; it will change!” Storms can unleash their fury seemingly out of nowhere.

Knowing what to do when a storm strikes can be life-saving.

Follow these tips on thunderstorm safety:

Become familiar with signs of a developing storm.

  • Large buildups of Cumulonimbus clouds (“cotton ball” clouds, especially those with dark coloration, and flattened or “anvil” shaped tops) are signs of a potential thunderstorm.
  • A sudden reversal in wind direction, a noticeable rise in wind speed, and a sharp drop in temperature may note the mature stage of a storm.

Heavy rain, hail and lightning can occur in the mature stage of a thunderstorm. During a storm, use the following guidelines:

  • Do not lie down
  • The best position is sitting on a day pack (only those without metal frames or components) or crouching with feet close together

Avoid sitting directly on the ground, if possible; but, if necessary, keep feet and buttocks close together.

Avoid grouping together—keep a minimum of 15 feet between people when possible.

Cell phones or hand held radios (with short rubber antennas) are safe to use. Do not use phones or radios with elevated antennas.

Wide, open spaces are better places to shelter than trees or near clumps of trees.

Ridge tops or other high places should be avoided.

If you feel the hair on your arms or head “stand up,” there is a high probability of a lightning strike in the vicinity. Crouch or sit on a day-pack (without metal frame).

Put down all tools, and distance yourself from them if possible.

Take shelter in vehicles whenever possible.

    “We huddled under the biggest, strongest tree we could find” – they’re lucky since the tallest tree is more prone to being struck.
    I’ve not heard of wide open space being better for shelter – the usual advice is shelter under a consistent canopy of forest so you are not higher than surrounding objects and odds favor you that lightning will strike any place.
    All three documents referenced as sources in the NPS ‘tailgate safety series’ mentioned above are ‘not found’.

    Hiking Dude, Thanks for alerting us that the reference links are no longer valid in the Safety Series document. I will alert the NPS and give them the references you provided. Thank you!
