An air pollution alert for parts of the state -- including the Twin Cities -- has been issued by the Minnesota Pollution Control Agency.
In addition to the metro area, the alert includes Rochester, St. Cloud and Brainerd, but not Duluth. The alert is coded ''orange,'' meaning air pollution levels are unhealthy for those with heart or lung disease (including asthma), adults over 50, and for healthy adults and children engaged in vigorous exercise in which they breathe deeply.
