Canadian wildfire smoke drags unhealthy air into Michigan

Michigan is under a statewide air-quality alert for July 15 as wildfire smoke from Canada and Minnesota raises PM2.5 levels. Plumes are expected to reach the Upper Peninsula first around midnight, then the northern Lower Peninsula, potentially hitting the Michigan–Indiana border by late Wednesday, with the UP likely seeing the most unhealthy air. Residents should limit strenuous outdoor activity, especially if they have heart or respiratory conditions, and check air quality via the MiAir Quality Index Dashboard, AirNow, or AccuWeather, with alerts available through EnviroFlash.
