...AIR QUALITY ALERT NOW IN EFFECT UNTIL 7 PM CDT SUNDAY...

* 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...East central, southeast, south central, and northeast
  Minnesota.

* WHEN...Until 7 PM CDT Sunday.

* 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...Heavy smoke from wildfires will persist
  across northeast Minnesota tonight into Sunday morning.
  Increasing southwesterly winds Sunday afternoon will lead to
  improved air quality for much of northeast Minnesota, though
  near the wildfires and near the shores of Lake Superior may
  continue to experience poor air quality through the Sunday
  afternoon. The alert for this part of the state is currently set
  to expire at 7 pm Sunday. Only localized poor air quality near
  the wildfires will continue thereafter. Heavy smoke is expected
  to then enter southeastern and far east central Minnesota from
  the east early Sunday morning and persist through Monday
  morning. Red, meaning unhealthy for everyone, is the expected
  AQI category for all of this alert.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
avoid prolonged or heavy exertion. The general public should limit
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.
