...AIR QUALITY ALERT IN EFFECT UNTIL 9 AM CDT MONDAY...

* 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 Purple or Very Unhealthy
  category.

* WHERE...North central and northeast Minnesota.

* WHEN...Until 9 AM CDT Monday.

* IMPACTS...The risk of health effects is increased for everyone.

* ADDITIONAL DETAILS...Heavy ground-level smoke from wildfires in
  central Canada moved into northwest Minnesota early Friday
  morning behind a cold front. This first band of smoke is
  currently impacting northern Minnesota as it moves east during
  the day Friday. Air quality will worsen across northeast
  Minnesota Friday evening as smoke arrives over the region. A
  second round of smoke will move into northwest Minnesota late
  Friday evening. This smoke will be more widespread as it moves
  southeast overnight, and by Saturday afternoon the entire state
  may be impacted. The heaviest smoke on Saturday will be across
  the northern half of the state. Air quality will begin to
  improve across western Minnesota Sunday morning as cleaner air
  moves in from the west. By Sunday evening, the smoke should be
  gone from most of the state. Another round of smoke is possible
  across far northern Minnesota Sunday night.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
avoid all physical activities outdoors. The general public should
avoid prolonged or heavy exertion. Reduce or eliminate activities
that contribute to air pollution, such as outdoor burning, and use
of residential wood burning devices. Reduce vehicle trips and
vehicle idling as much as possible. Keep windows closed overnight
to prevent smoke from getting indoors.
