Haze from smoke drifting south from wildfires burning in Canada continues to linger over Colorado, prompting the state's health department to issue a wildfire smoke health advisory for much of the Front Range. The advisory includes El Paso, Pueblo, Huerfano, Las Animas and Otero Counties, and is set to expire at 4 PM Wednesday. (UPDATE: The advisory has been extended until 9 AM Thursday.)
Colorado Health and Public Environment says if smoke becomes thick, residents might consider staying indoors, especially those with heart disease and respiratory illnesses; children and older adults are also at risk. If visibility is less than five miles due to the presence of smoke, then conditions are considered unhealthy.
Expected rain may help clear out some of the haze.
