Colorado’s air quality has prompted an alert for unusually sensitive people that’s in effect until 4 p.m. Sunday.
The ozone concentrations are expected to be in the good to moderate range on Saturday, but on Sunday they could rise to be unhealthy for sensitive groups in parts of the western suburbs of the Denver area and in the adjacent foothills during the afternoon and evening, according to an alert issued by the Colorado Department of Public Health and Environment.
“Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion on Saturday and Sunday from noon until 10 p.m.,” the alert states. Sensitive groups include people with lung disease, such as asthma, people with cardiopulmonary disease and older adults.
The department also issued an advisory for wildfire smoke from Walden.
Areas of northwestern Jackson County, and other locations to the northeast, east and southeast of the fire could produce moderate to heavy smoke that could be unhealthy. The department recommends limiting outdoor activities, especially sensitive groups such as those with respiratory conditions.
“During the overnight hours Saturday night and into Sunday morning, smoke will likely drain into northern parts of North Park,” the advisory states. “This could potentially pool a significant amount of smoke along Highway 125 from Cowdrey into southern Wyoming.”
