Winds gusting to more than 80 miles per hour swept across Colorado Thursday, fanning a wildfire that forced the evacuation of 200 families, shattering windows, overturning tractor-trailers and knocking out power to traffic signals during the morning commute.
In Colorado Springs, the Red Cross set up a shelter for people who were displaced because of power outages.
Authorities say a wildfire near Conifer west of Denver may have been started by sparks from wind-whipped power lines. The fire charred up to seven acres before it was contained early Thursday and residents were allowed to go home.
No houses were damaged.
The Colorado State Patrol banned tractor-trailers and large recreational vehicles on Interstate 25 from Castle Rock south to the New Mexico line and north of Fort Collins.
Winds also knocked electrical transformers into trees, cutting power in some areas.
