Denver, Colorado – Hot, stagnant weather is gripping Colorado’s Front Range, pushing ozone pollution into unhealthy levels for sensitive groups through 4 p.m. Monday. Drivers and outdoor enthusiasts across Denver, Boulder, Fort Collins, and surrounding counties should brace for poor air quality, especially in western metro neighborhoods and along I-25 north.
According to the Colorado Department of Public Health and Environment, an Ozone Action Day Alert remains in effect until late Monday afternoon for Douglas, Jefferson, Denver, Boulder, Weld, Larimer, Adams, Arapahoe, and Broomfield counties. State officials urge residents to limit driving gas or diesel vehicles and cut back on outdoor exertion, especially children, adults who are active outside, and anyone with asthma or lung disease.
The warning arrives as wildfire smoke continues to drift across western and southern Colorado, with a separate Air Quality Health Advisory in place for La Plata, Gunnison, Montrose, Delta, Mesa, and more until 9 a.m. Monday. Residents from Durango to Telluride and up toward Gunnison may see visibility drop below five miles as smoke settles in overnight, prompting officials to recommend staying indoors if air appears thick.
State health leaders suggest charging devices, keeping windows closed, and using air filtration if possible. Anyone feeling symptoms like coughing or trouble breathing should avoid outdoor activity until conditions improve.
Both air quality alerts could extend if high temperatures and wildfire activity persist. Stay tuned to local agencies for the latest updates and advisories.
