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.

Governor Jared Polis on Sunday made a verbal disaster declaration for a series of wildfires burning in Montrose, Delta and Mesa counties, according to a news release.

The fires varied in size but have already forced several evacuations and pre-evacuation notices, closed a national park, and the Deer Creek Fire near the Utah state line has already destroyed at least five buildings.

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