UPDATE #1 8/5 5:00 PM – Mesa County Public Health is extending its Air Quality Advisory through 8:00 PM on Friday, August 6.


Due to moderate smoke in the region, MCPH has issued an Air Quality Advisory from 9:00 AM to 4:00 PM on Thursday, August 5.

The expected Air Quality Index (AQI) ranges from good to moderate, and the smoke dispersal forecast ranges from poor to fair throughout the day.

We assume the smoke to be wildfire-related, as it is not uncommon for haze from in-state and out-of-state fires to impact our air quality in the summer months. 

When air quality is in the moderate or poor range, there’s an increased risk for people in sensitive groups, including people with heart or lung disease, older adults, and young children. If visibility is less than five miles due to smoke, the smoke has reached unhealthy levels.

Residents are advised to take the following precautions to stay healthy:

  • Avoid heavy outdoor exertion such as running or other forms of exercise.
  • Keep your indoor air clean and stay inside as much as possible.
  • Avoid activities that increase indoor pollution. You want to keep your indoor air as clean as possible.
    • Do not vacuum. It stirs up dust in your home.
    • Do not smoke tobacco in your home.
    • Contact your health care provider if you’re concerned about your health.
