New fires spark in western Colorado, fires in other states still active

Several wildfires are creating air quality concerns in areas of western Colorado. The Grease fire and the Elk fire are located in central and eastern Rio Blanco County, and the Coulter Creek fire is located in southeastern Garfield County. These fires will produce areas of moderate to heavy smoke on Sunday evening and Monday morning, particularly in areas of low lying terrain in the immediate vicinity of the fires.

An Air Quality Health Advisory for Wildfire Smoke has been issued for areas near these fires through at least Monday morning. Folks in these areas should take steps to avoid exposure to smoke and limit health impacts. 

Fires in other states continue to produce smoke, resulting in light to moderate concentrations of fine particulates in other areas of the State. While conditions across the western slope and 4-Corners regions of Colorado do not warrant advisories at this time, anyone in these areas should also remain aware of air quality conditions due to the presence of smoke.

We will continue to provide updated information on smoke impacts, including additional advisories if necessary.
