Sunday Pollution Forecast For Metro Denver, Boulder

Air quality in metro Denver and Boulder improved Saturday, however smoke continues to flow in from the Cameron Peak and Mullen wildfires.

Fine particulate matter concentrations from the smoke are expected to be in the 'unhealthy for sensitive groups' and 'moderate' categories on Sunday along the Front Range, according to the Colorado Department of Public Health and Environment.

"Although air quality conditions have generally improved across much of the Front Range region on Saturday, fire activity is increasing at both the Cameron Peak and Mullen wildfires," the agency said in an air quality advisory.

"This may result in increasing fine particulate concentrations across the region through Sunday morning, especially for locations near the fire in central and western Larimer County, along with the I-25 corridor from Ft. Collins southward to Denver and perhaps Colorado Springs."

Visibility along the Front Range is expected to be in the 'poor' category Sunday, public health officials said.

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