Poor Air Quality

Health Advisory

You may continue to notice smoke in the air surrounding Lyons. Smoke from the Cameron Peak fire in western Larimer County is expected to result in concentrations of fine particulate matter that are Unhealthy for Sensitive Groups, with some areas reaching the higher Unhealthy category. The Colorado Department of Public Health and Environment has issued an ACTION DAY ALERT until at least 4 p.m. Monday, September 7, 2020 for the Front Range Urban Corridor from Douglas County north to Larimer and Weld counties, including the Denver-Boulder area, Fort Collins and Greeley.

Concentrations of fine particulates in the Unhealthy category are most likely for localized areas directly downwind of the Cameron Peak wildfire, including Ft. Collins and Longmont. Fine particulate concentrations in the Unhealthy for Sensitive Groups category are likely for the rest of the northern Colorado Front Range region, including locations from the Denver Metro area northward to Fort Collins and Greeley.

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.

This Particulates Action Day Alert will remain in effect until at least 4 p.m. Monday, September 7, 2020.
