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 the elderly. 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 smoke from several in-state and out-of-state fires is impacting large sections of western Colorado. Periods of moderate to heavy smoke can be expected Wednesday through Thursday morning within the advisory area, especially in areas near local wildfires. The highest impacted areas will include locations near the Bull Draw Fire near the Montrose/Mesa County line, the Cabin Lake Fire in Rio Blanco County, and the Silver Creek Fire near the Routt County/Grand County line. Additional fire activity is possible near the Plateau Fire near the Dolores/Montezuma County line.
