Smoke is moving into Colorado

Smoke from several out-of-state fires is moving into Colorado. The heaviest smoke is expected in western Colorado. However, hazy skies and light smoke are possible throughout the state.

Air Quality Health Advisory

An Air Quality Health Advisory is in effect for a large section of the state. Counties in western, southwestern, and southern Colorado are all included. Smoke is moving in from fires to our west, which will impact air quality on Tuesday and Wednesday.

Even if the smoke is not heavy right now, conditions could change rapidly. To stay aware of the latest air quality conditions near you, check the AirNowFire and Smoke Map. Take steps to protect your health if the smoke becomes heavy in your area.  

Where is it all coming from? In Utah, the Cottonwood Fire, Hastings Fire, and Iron Fire have grown over the past 24 hours and are producing heavy smoke. The Kane Springs Fire and Grapevine Fire are burning in Nevada, contributing to the plume.

Beyond the advisory area

In the satellite image above, the plume of smoke extends into eastern Colorado. However, we did not include this area in the Advisory. We expect most of this smoke to remain in the upper atmosphere and not mix down to the surface. If you're located outside of the advisory area, you may notice hazy skies and light smoke, but no major public health impacts are expected at this time.

CDPHE is monitoring the situation and will adjust the advisory area if conditions change.
