DENVER -- A smoke advisory for all of Colorado east of the Continental Dive was issued by the Colorado Department of Public Health & Environment on Tuesday because of wildfires in Canada.

Denver International Airport also warned travelers that thick haze could delay flights, though the Federal Aviation Administration lifted the traffic management program late in the morning as the haze began to thin out.

The advisory covered the entire northern and southern Front Range region, including Denver, Boulder, Fort Collins, Greeley, Colorado Springs, Pueblo, Trinidad, Lamar, Burlington and Sterling.

The advisory was in effect until 4 p.m. Rain showers moved in at that time.

"If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly," the advisory reads. "If visibility is less than 5 miles in smoke in your neighborhood, smoke has reached levels that are unhealthy."
