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: Moderate to heavy concentrations of smoke from California wildfires will continue to move into Colorado on Tuesday and Wednesday, affecting northwestern and north-central portions of Colorado. Expect the heaviest smoke impacts in sheltered valley locations where atmospheric mixing is more limited. Some intermittent clearing is possible on Tuesday and Wednesday, however residual health impacts may linger from prolonged exposure to elevated smoke concentrations.
