Published 8:09 am Thursday, December 13, 2018

The Minnesota Pollution Control Agency (MPCA) has expanded the current air quality alert for the Twin Cities and portions of central Minnesota, effective 2 p.m. Tuesday, Dec. 11 through 6 p.m. Thursday, Dec. 13 to include southeast Minnesota.

The affected area now includes the Twin Cities, Willmar, Hutchinson, Mankato, Albert Lea, Rochester, Winona, and the Tribal Nations of Prairie Island and Upper Sioux.

Fine particle levels will continue to be in the Orange (Unhealthy for Sensitive Groups) category in the Twin Cities metropolitan area and central Minnesota this morning due to stagnant weather conditions. Fine particle levels have also reached the Orange category across southeast Minnesota. Light winds, fog, and a strong inversion have resulted in poor dispersion of air pollutants and they are accumulating and becoming trapped near the ground.

These conditions will continue over the next couple of days as this plume of fine particles will slowly move across central and southeast Minnesota. Fine particle levels in the alert area are expected to remain near or above 100 AQI until Thursday afternoon, when a front moves across the state and brings cleaner air into the region.
