Smoke-filled skies are expanding over many parts of Colorado, blocking mountainviews and prompting ongoing air quality concerns.
Smoke from the Pine Gulch, Cameron Peak, Williams Fork, and Grizzly Creek wildfires prompted officials from the Colorado Department of Public Health and Environment (CDPHE) to issue several air quality health advisories warning of “gusty erratic winds” sending smoke in almost any direction.

The majority of the advisories are set to remain in effect for 24 hours, from 9:00 a.m. on Monday through 9:00 a.m. on Tuesday. There is a possibility for extension.
If visibility is less than 5 miles due to smoke in your neighborhood, the smoke has reached levels that are unhealthy. The CDPHE recommends staying indoors, especially for those with heart disease or respiratory illnesses. The same applies to the very young and elderly.

According to the advisories, smoke from the Williams Fork Fire will likely impact areas along Ute Pass Road, Williams Fork, Larimer County, and other locations along the Front Range.
Ozone and fine particulate concentrations could both reach unhealthy for sensitive groups at times through at least the afternoon, with the greatest air quality impacts in the Denver Metro area, and northward along the I-25 corridor to Longmont, Fort Collins, and Greeley. This includes areas west of I-25 within the lower foothills, especially in Larimer County.
Meanwhile, heavy overnight smoke from the Grizzly Creek Fire will remain possible for locations along Interstate 70 in central and eastern Garfield County.
Hazy skies are expected as smoke drifts along the following areas; Silt, Eagle, Vail, Mack, Loma, Fruita, Grand Junction, Aspen, Delta, Parachute, Rifle, Glenwood Springs, Carbondale, Rand, Kremmling, Granby, Winter Park, Breckenridge, Silverthorne, Georgetown, Central City, Fairplay, Ft.
