The Minnesota Pollution Control Agency has issued an air pollution health alert for the Twin Cities area.
Overnight, fine particle pollution reached levels considered unhealthy for sensitive groups, according to the MPCA.
Winds are expected to help the air quality improve throughout the day. The air pollution alert is expected to last through midnight.
An alert has also been issued for the Rochester area.
Members of these groups are encouraged to postpone or reduce vigorous activity and minimize exposure to local sources of air pollution (i.e., heavy duty vehicle traffic, wood fires, and candles). Even individuals who are otherwise healthy may experience health effects when pollution levels increase.
