Extremely high winds in Wyoming , Colorado and California overturned a number of tractor-trailers yesterday, and knocked out power in much of Colorado Springs , CO .

In Wyoming , winds of up to 72 mph overturned three semis on Interstate 25. One driver received minor injuries. Wyoming Highway Patrol Sgt. Stephen Townsend told Land Line that two of the trucks were empty and one was only lightly loaded.

Townsend says the same kind of high winds overturn tractor-trailers every year, and that many truckers simply pull over and wait for the winds to die down, while others chance it.

“In fact, two of (the trucks) turned over about four miles south of Cheyenne ,” Townsend said. “At the next interchange, another mile down, there were several trucks that had taken the offramp and were … just waiting it out. They didn’t want to take a chance and go any further and suffer the same fate.”

The Associated Press reports that, in Colorado , 84-mph winds overturned several tractor-trailers, including one that forced the temporary closure of U.S. 287 north of Fort Collins .

In Washoe County , CA , a truck on U.S. 395 overturned on an embankment, according to The AP. No injuries were reported, and the roadway was not closed.
