Heavy winds that swept through Black Canyon of the Gunnison National Park on Sunday night started “rapid fire spread” after a relatively slow day of growth, according to fire officials.

The fire burning since Thursday in Black Canyon of the Gunnison National Park is now at more than 3,500 acres and is still 0% contained, National Park Service officials said in a Sunday update.

Five wildfires are burning on thousands of acres in western Colorado, including one that crossed into the state from Utah, fire officials said Sunday.
