It has been an eventful day in Colorado, to say the least. We are tracking smoke in three separate areas.
First, multiple fires have sparked in western Colorado, including the South Rim Fire. An Air Quality Health Advisory is in effect for Montrose, Delta, and southern Mesa Counties until 9 am Friday morning.
Fire hotspots (in red) on GOES-19 Satellite imagery. Multiple fires have sparked this afternoon in Colorado and Utah.
Second, smoke has moved into the Front Range. Particulate Matter concentrations in Longmont, Boulder, and Denver are starting to climb. This smoke originated from the Mount Irish Fire in Nevada. Smoke in the upper atmosphere moved into Colorado this morning. Now, that smoke has mixed down to the surface.
Third, the Mount View fire is burning north of Buena Vista. Refer to the Chafee County Sheriff's office for the latest information on evacuations. We do not expect any major public health impacts from smoke in this area. We will watch the situation and provide an update if anything changes.
If you are sensitive to smoke or near a fire, it's a good idea to take steps to protect your health. For the most up-to-date air quality data, check out CDPHE's monitors or PurpleAir sensors.
