Red flag warnings remain in Colorado as wildfires continue to spread

GRAND COUNTY, Colo. - Firefighters in Colorado have yet to get a handle on the East Troublesome fire, one of multiple currently raging in the state, as mandatory evacuations remain in some areas.

The wildfire, near the foothills of Fort Collins, Colorado, has burned more than 318 square miles to become the largest in state history. As of Friday, The U.S. Forest Service reported the East Troublesome wildfire was only 5% contained.

Firefighters contained the Calwood fire at 55% after it burned more than 10,000 acres. The Cameron Peak fire was contained at 57% after burning nearly 207,000 acres.

Authorities put red flag warnings in place Friday. This, after fire areas experienced strong southwest winds throughout Thursday.

The blazes have burned the second-most acreage since 2000 and included the state's two largest on record. One of Colorado’s smaller fires exploded late Wednesday from 30 square miles to 196 square miles and closed Rocky Mountain National Park.
