Overview
- EGLE issued the alert Sunday for elevated fine particulate (PM2.5) levels that reached the Unhealthy for Sensitive Groups range.
- The advisory covers Oakland, Wayne, Livingston, Macomb, Washtenaw, St. Clair and Monroe counties through noon Monday, Feb. 16.
- Snowmelt releasing trapped particles, very light winds and a strong temperature inversion are concentrating pollution near the ground.
- Officials urge people with heart or lung disease, older adults and children to limit outdoor activity, avoid open burning and cut back on pollution‑generating tasks.
- The February alert is considered unusual, and conditions are expected to ease once vertical mixing resumes later Monday.
