Residents of Boulder County are experiencing hazy skies on Wednesday due to smoke from wildfires in Canada’s Northwest Territories. The haze is visible across the Front Range and in Eastern Colorado and is expected to linger through Thursday when a change in wind direction may carry the smoke away from the state. In addition The Colorado Department of Public Health and Environment and the Regional Air Quality Council have issued an OZONE ACTION DAY ALERT at 4 p.m. on Wednesday, July 2, 2014 for the Front Range Urban Corridor from El Paso County north to Larimer and Weld counties, including the Denver-Boulder area, Colorado Springs, Fort Collins and Greeley.
Warm temperatures, abundant sunshine and generally light winds will allow ozone concentrations to reach the Unhealthy for Sensitive Groups category on Wednesday and Thursday, particularly for foothill locations from west of Denver northward to the west of Ft. Collins.
This Ozone Action Day Alert will remain in effect until at least 4 p.m. Thursday, July 3, 2014.
