Another day of heat and humidity also brings an air pollution warning.
The Minnesota Pollution Control Agency (MPCA) issued an air pollution health advisory for a significant portion of the state that includes parts of eastern, southern and southwestern Minnesota, they said in a release.
The advisory lasts from 10 a.m. Saturday to 9 p.m. Saturday night. Some cities in the affected area include the Twin Cities metro, Mankato, New Ulm, Albert Lea, Fairmont and Marshall.
Forecasted temperatures in the low 90s in this area with clear sunny skies, and light and variable winds will lead to the formation of ground level ozone.
As a result, the Air Quality Index (AQI) is forecasted to reach just below air quality conditions considered unhealthy for sensitive groups, including people with preexisting respiratory or cardiovascular conditions, the elderly, children and individuals who participate in outdoor activities requiring extended or heavy exertion.
People in those groups are encouraged to postpone or reduce vigorous outdoor activity, or schedule outdoor activity in the morning, when ozone levels are lower.
Even persons who are otherwise healthy may experience health effects when ozone levels increase.
