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: Heavy smoke from California wildfires will begin to move into northwestern Colorado Friday afternoon and spread in a southeasterly direction across the rest of western and central Colorado Friday night into Saturday morning. Expect the heaviest smoke impacts in sheltered valley locations where atmospheric mixing is more limited.
