Tuesday Smoke, Pollution Forecast For Front Range

Just when Front Range residents catch a short break from the intense smoke pollution, another blanket of particulates flows in from the Cameron Peak and Mullen wildfires.

Fine particulate matter concentrations from the smoke are expected to be in the 'unhealthy' to 'unhealthy for sensitive groups' categories on Tuesday in Denver's metro area and Boulder, according to the Colorado Department of Public Health and Environment.

"The entire Front Range region remains under an Action Day for Fine Particulates until at least 4 pm Tuesday," the agency said in an air quality forecast.

"Moderate to heavy smoke is expected to linger Monday night through Tuesday morning throughout the Front Range region," the alert read. "People with heart or lung disease, older adults, and children should reduce prolonged or heavy exertion on Monday and Tuesday."

Visibility along the Front Range is expected to be in the 'poor' to 'extremely poor' categories Tuesday, public health officials said.

Ozone concentrations in metro Denver and Boulder are expected to be in the 'good' to 'moderate' categories.
