I wonder what the maximum wind speed a forest can experience without catastrophic damage.

Obviously, a tent in a dense forest needn't withstand particularly high winds, or if it does, it's likely to get flattened by a tree before it fails.

Perhaps a sustained 25 mph wind on forest floor would constitute a very unusual and somewhat dangerous situation that doesn't relate to tent selection, unless they're making steel tents these days.

The measured wind speed, as reported or forecast by National Weather Service, might be a higher value, given their siting requirements for anemometers.

This is a way of restating my thesis that most winter backpackers don't need a "winter" tent.

Those that maybe do, often chose to hike another mile to some miserabley windy place above treeline, when they can easily camp lower down for privilage of getting a peaceful night's sleep --- or perhaps getting nailed by a tree in their tarp or in their $800 12-pound (or whatever) expedition tent.
