The Minnesota Pollution Control Agency the severity and geographic range of the air pollution health advisory issued yesterday has grown.
Two-thirds of of the state is now under an air pollution health alert. In this portion of the state, air quality conditions are considered unhealthy for sensitive groups. The MPCA says strong temperature inversions, snow melt, and morning fog are trapping fine particle pollution near the surface across much of the state today. Air quality conditions are expected to improve as a slow moving frontal system passes over Minnesota.
