Wildfire Smoke Sets Michigan on Air‑Quality Watch

A statewide alert has been issued for Sunday because smoke from distant wildfires is expected to drift across Michigan. The warning began Saturday for the Upper Peninsula and northern Lower Peninsula, then will cover the entire state on Sunday.

• Cold front impact: A cold front that swept through Southeast Michigan earlier today briefly lifted pollution levels.
• Current conditions: The cooler, drier air behind the front is now carrying more smoke.
• Health advisory: The National Weather Service predicts conditions that will be “unhealthy for sensitive groups” in the Lower Peninsula and “unhealthy” overall in the Upper Peninsula.

CBS News Detroit has labeled Sunday a “NEXT Weather Alert Day.” Similar air quality could push Monday into the same category. Temperatures in Southeast Michigan will reach the 70s and 80s, adding to discomfort for those exposed.

Health officials advise:

• Keep windows shut overnight.
• Run air‑conditioning units with filters rated at least 13.
• Those with preexisting heart or lung conditions should take extra precautions, as polluted air can trigger inflammation and raise blood pressure.
