Denver, Colorado – Residents across Colorado’s Front Range are facing another Ozone Action Day as hot, stagnant conditions drive air quality to unhealthy levels for sensitive groups through Monday afternoon. The alert covers Denver, Boulder, Fort Collins, and surrounding suburbs, with the highest ozone concentrations expected along the foothills and urban corridor.
According to the Colorado Department of Public Health and Environment, ozone levels will climb into the “Unhealthy for Sensitive Groups” range on Monday due to high temperatures, sunshine, and little wind. Those with asthma, lung disease, active children, and older adults are urged to limit prolonged or heavy outdoor activity, especially from now through 4 p.m. Monday.
Drivers are asked to reduce use of gas and diesel vehicles until Monday evening to help cut down on pollution. Western suburbs including Broomfield, Jefferson, Arapahoe, and Adams counties will also see elevated ozone levels.
Meanwhile, wildfire smoke from several fires in Rio Blanco, Garfield, and Eagle counties will create hazy, at times unhealthy air across Western Colorado, especially near Meeker, Carbondale, and Glenwood Springs. If smoke becomes thick or visibility drops below five miles, residents should remain indoors and consider relocating if breathing becomes difficult.
Air quality alerts are likely to continue if high heat and stagnant weather persist into Tuesday.
