Michigan Air Quality Alert: Ongoing Canadian Wildfire Smoke

Is the air quality good in Michigan?

Michigan’s air quality as of July 26, 2023 ranges from “unhealthy for sensitive groups” to unhealthy, particularly in the Lower Peninsula and Detroit. Smoke from wildfires in Canada has drifted into the state, leading to high levels of fine particles, PM2.5 (1)(2)(3).

PM2.5, particulate matter measuring 2.5 microns in diameter or less, has been linked to respiratory and cardiovascular disease.

What is causing poor air quality in Michigan?

The primary cause of poor air quality in Michigan is the heavy smoke pollution from more than 1,000 actively burning Canadian wildfires. These wildfires have been ongoing since May, and their smoke continues to drift into the U.S., particularly affecting regions like the Great Lakes and the Northeast.

Are there any other weather concerns for Michigan?

In addition to the poor air quality, Michigan is also facing the threat of severe storms, high winds, large hail, localized flooding, and the possibility of isolated tornadoes.
