Grand Rapids, Mich. – Residents in southwest and west Michigan should be cautious about outdoor activities this weekend, as an air quality advisory remains in effect through Sunday evening due to high ozone levels.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued the alert for June 21–22, warning that ozone concentrations will reach the “Unhealthy for Sensitive Groups” range.
Details of the Air Quality Advisory
The advisory affects Berrien, Cass, Muskegon, Ottawa, Kent, Allegan, and Van Buren counties, including cities like Grand Rapids, Benton Harbor, St. Joseph, and Holland. With temperatures soaring into the 90s and abundant sunshine, southwest winds are creating ideal conditions for the formation of ground-level ozone along the Lake Michigan shoreline.
Health Risks and Safety Measures
Ozone pollution can cause breathing difficulties, especially for individuals with asthma or other respiratory conditions. The National Weather Service advises those in sensitive groups to limit outdoor exertion, particularly during the afternoon when ozone levels tend to peak.
Residents are also urged to take steps to reduce ozone-forming emissions by postponing non-essential errands, avoiding gas-powered lawn tools, and refraining from vehicle refueling during peak hours. Telecommuting, walking, or using water-based paints can further help minimize ozone formation.
What to Expect Through Sunday
This marks one of the season’s most widespread ozone alerts, similar to conditions seen during July 2021. The advisory remains in effect through Sunday evening, with updates available on airnow.gov and MiAir.
As high temperatures and ozone levels combine this weekend, residents in Grand Rapids, Benton Harbor, and surrounding areas should take precautions to protect their health, especially those in sensitive groups. Limit outdoor activities, reduce emissions, and stay informed for updates on air quality conditions.
