A rare tornado brought wind speeds of up to 100 miles per hour to Cripple Creek in Teller County, Colorado, near Colorado’s famous Pikes Peak mountain, on Friday afternoon.

Video shared by AccuWeather Footage about the damage from the storm several days after the tornado, pointing out how rare it is for a tornado to form in high elevation areas. The location where Friday’s tornado struck is at an elevation of 10,050 feet. Video showed downed trees.

“It was the second EF1 tornado in just over a year at high altitude. One also struck near Pikes Peak on July 20, 2023,” the video says. “Tornadoes are less common in high mountains because mountains often disrupt the circulation of severe thunderstorms. The highest tornado ever documented was a photo of a tornado at 12,156 feet in California in 2004.”

Tornadoes are rated on the Enhanced Fujita Scale (EF scale), the NWS explained on its website. The EF scale rates a tornado based on the storm’s estimated wind speeds and associated damage. The EF scale ranges from 0 to 5, with wind speeds ranging from 3-second gusts at 65 to 85 mph for an EF-0 to over 200 mph for an EF-5. For an EF-1, wind speeds range from 86 to 110 mph.

According to a report from the Weather Channel, an EF-1 tornado can cause “moderate damage,” such as heavily damaged roofs, overturned mobile homes, or shattered windows.
