Fire whirl forms in Beaver Creek

Crews in northern Colorado are still working to put out the Beaver Creek fire that started in June. One of the firefighters took a picture of a fire whirl he found while on the front lines.

According to the Stormtracker 13 weather team, fire whirls are caused by hot air rising. When this happens, exterior winds can cause the air to rotate. Flames can be associated with these structures and are known as fire whirls or fire tornadoes.

So far, the Beaver Creek fire has burned more than 36 thousand acres, and is 44 percent contained. Crews are expected to have the fire fully contained by late October.
