Denver, Colorado – Hot, stagnant air is expected to push ozone levels into unhealthy territory for sensitive groups across the Denver metro and Front Range through 4 p.m. Thursday, prompting health officials to issue an Ozone Action Day Alert.
According to the Colorado Department of Public Health and Environment, residents in Denver, Boulder, Broomfield, Douglas, Jefferson, western Arapahoe, western Adams, Larimer, and Weld counties should reduce gas and diesel vehicle use and limit outdoor activity, especially for those with asthma, lung disease, or for children and older adults.
