Public Health Recommendations: If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and older adults. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill. If visibility is less than 5 miles in smoke in your neighborhood, smoke has reached levels that are unhealthy.

Outlook: Widespread moderate to heavy smoke has been observed across much of the advisory area Thursday morning. Additional heavy smoke is possible Thursday afternoon and evening, and into Friday morning, for areas downwind of the wildfires in Rio Blanco County. Smoke impacts may shift northward on Thursday, impacting areas along and north of Interstate 70 within the advisory area.
