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

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.

More than a dozen fires are creating heavy smoke, with more lightning and gusty winds expected for parts of the Western Slope Friday.
