WHAT: The Minnesota Pollution Control Agency has issued an Air
Quality Alert for fine particles pollution. The Air Quality Index
(AQI) is expected to reach the Red or Unhealthy category.
WHERE: Southeastern Minnesota.
WHEN: Until 11 AM CDT Friday.
IMPACTS: Some members of the general public may experience health
effects. Sensitive groups, such as people with lung disease
(including asthma), heart disease, and children and older adults, may
experience health effects.
ADDITIONAL DETAILS: Dense smoke is being pulled by a quasi-
stationary front across southern Minnesota. Smoke will arrive along
the I-90 corridor Wednesday evening. The smoke will have a rapid
onset with visibility rapidly declining. There will be a sharp
gradient of smoke, with some areas of the same counties experiencing
Good/Green air quality while other experience Red/Unhealthy for All
conditions as the front slowly moves south. Conditions will gradually
improve by Friday morning as the front retreats northward.
