Wildfire smoke
Wildfire smoke
In recent years, Michigan has seen unprecedented levels of wildfire smoke drifting across its communities and much of the rest of the country.
In addition to pollutants like fine particulate matter carried in the smoke, there are gasses containing the chemicals that – when combined with sunlight – form ground-level ozone. These chemical reactions contribute to elevated ozone levels seen in areas across Michigan. It is important to take steps to protect yourself from wildfire smoke.
How we respond to wildfire smoke
Our meteorologists use air models to forecast when air quality may be poor. They will issue air quality advisories and alerts whenever conditions call for them
Monitor Michigan air quality
We share real-time pollutant monitoring data alongside the color-coded Air Quality Index (AQI)
Spread the word on social media
We use social media to get the word out about alerts, advisories, and actions residents can take to stay safe
Respond to media inquiries
Our team works with local media to inform and educate viewers about air quality and wildfire smoke
Answer your most common questions
We provide answers to frequently asked questions about how wildfire smoke impacts air quality in our communities
And most importantly: we issue advisories and alerts
An advisory is issued when levels of ozone or PM2.5 are expected to be “unhealthy for sensitive groups”
An alert is issued when levels of ozone or PM2.5 are expected to be “unhealthy”, “very unhealthy” or “hazardous”
There is nothing the state can do to reduce the pollutants from the fires drifting over from Canada.
However, state agencies, including EGLE, Health and Human Services, Natural Resources and Agriculture and Rural Development are working together to give Michiganders the latest information on how to be informed and protect yourself and your loved ones when air quality may be harmful.
