Wednesday Pollution Forecast For Front Range: More Smoke Expected

Pollution and smoke are expected to worsen in some metro Denver and Boulder regions Wednesday.

Wildfire smoke — from southern Wyoming's Mullen fire — is expected to flow into northern parts of the Front Range region early Wednesday morning, according to the Colorado Department of Public Health and Environment.

Fine particulate matter concentrations from the smoke are expected to reach the 'unhealthy for sensitive groups' category in many areas.

Visibility along the Front Range will likely be 'poor' Wednesday, public health officials said.

Ozone concentrations are expected to be in the 'good to moderate range," so unusually sensitive people should consider reducing prolonged or heavy outdoor exertion.
