Smoke to continue filling Colorado’s sky

DENVER -- A smoke-filled sky around Colorado is creating health concerns for those with respiratory issues, and greatly contributing to ozone problems.

The Regional Air Quality Council issued an Ozone Action Alert for Thursday night.

"Ground-level ozone pollution is created when emissions from everyday items -- such as gas powered vehicles and lawn equipment, household paints, stains and solvents -- combine with other pollutants in the atmosphere on hot, summer days," the RAQC said in a statement.

These conditions aren't likely to change based on a warm and mostly dry forecast with the exception of clouds, rain and cooler temperatures Friday.
