The northern half of Colorado is under a smoke health advisory that is expected to last at least through today morning due to large wildfires burning across much of the Northwest.

The Colorado Department of Public Health and Environment issued the advisory at 8 a.m. Friday, warning that much of the northern half of the state, including Garfield and Pitkin counties, could be unhealthy for sensitive groups because of the amount of fine particulates in the air.

Sensitive groups include the very young and elderly, as well as individuals with heart disease or respiratory illnesses.

The state agency warned that smoke reaches unhealthy levels if visibility is less than 5 miles, and that outdoor activities should be limited in areas of moderate to heavy smoke.

The health department advisory remains in effect at least until 9 a.m.

More significant relief will likely come later this weekend or early next week when incoming wind patterns flow back around from the southwest, according to Norv Larson, a meteorologist with the National Weather Service in Grand Junction.

“That should erode the smoke in the area,” he said.

As of Thursday, the National Interagency Fire Center reported 76 active large fires, most of which are located in the Northwest. None of those were in Colorado.
