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 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.
