I recognize the area of that vid which is on I-25 between Casper & Cheyenne, having been thru WY many many times on both the southern I-80 and north-south I-25 routes in all four seasons. High winds are the normal, and above norm when major weather fronts from the west come thru. And being high elevation WY catches more of the high-altitude winds.
The various mountain ranges help accelerate the westerlies wind due to orographic-lift and creates what's called Chinook Winds from west to east (at least in my state), plus any weather diving down from Canada don't have anything to slow it down.
WY has a lot of wind farms NE of Casper & between Cheyenne & Laramie.
Snow fences ae common along both Interstates because of the winter winds, as well as the highway gates, on both, that they close when things get nasty.
On the I-80 route I travel east to west very early in the morning when things are calmer, and when going west to east I time it to get on I-80 at sun-up to catch a tail-wind when the westerlies startup.
Plus the Dakotas & eastern MT are notorious for high winds.
