The Minnesota Pollution Control Agency has issued an air pollution health alert for western Minnesota effective through noon on Friday. The agency says a strong temperature inversion, snow melt and fog are trapping fine-particle pollution near the surface, causing unhealthy levels for sensitive groups. An air pollution health advisory has also been issued for the southern half of Minnesota — including the Twin Cities and Rochester — beginning Thursday evening and extending into Friday morning. Fine-particle concentrations are expected to increase and may reach unhealthy levels for sensitive groups for short periods.
