Yellow Lake fire could bring smoke to Colorado

 We will be closely watching fire activity on the Yellow Lake wildfire in northern Utah on Monday.  If the fire gets active and produces smoke, it could be sent into western Colorado tonight and during the day on Tuesday.  The image below is courtesy of the Uinta-Wasatch-Cache National Forest Facebook page where you can also get updated information on the fire's behavior.

In addition to smoke from the Yellow Lake wildfire, a cold front could bring some smoke into northwestern Colorado tonight from fires in Wyoming.  All that being said, surface concentrations of PM2.5 (fine particles, which are the primary health risk from transported wildfire smoke) could very well be elevated tonight/Tuesday from northwestern Colorado (Craig, Meeker, etc.) southward into the Grand Valley which could impact Grand Junction.  In these areas, you may want to keep an eye on air quality monitors on the EPA's Fire and Smoke Map.  If you want to play it safe, close your windows before going to sleep tonight.

We will continue to monitor the smoke and post air quality advisories here, if necessary.
