Air pollution health advisory issued
The Minnesota Pollution Control Agency (MPCA) has issued an Air Pollution Health Advisory through Friday due to elevated levels of fine airborne particulates for most of Minnesota, with the worst air quality occurring in the Twin Cities and Rochester.
Stagnant winds overnight are helping trap fine particles and allowing them to build. These conditions are expected to continue until Friday, resulting in marginal air quality. The Air Quality Index (AQI) hit 103 in Rochester this morning. The Twin Cities AQI is 92 this morning and may climb near 100.
The north and northwest part of the state will have fair air quality but the southern two-thirds of Minnesota including Brainerd, Duluth and St. Cloud and southward will experience marginal air quality that may reach peak AQI readings near 90 over the next several days.To learn more or to check hourly updates of the AQI, visit:http://aqi.pca.state.mn.us/
