...AIR QUALITY ALERT NOW IN EFFECT THROUGH 3 PM CDT TUESDAY...

...LONG DURATION AND UNPRECEDENTED SIGNIFICANT AIR QUALITY EVENT
UNFOLDING ACROSS MINNESOTA...

* WHAT...The Minnesota Pollution Control Agency has issued an Air
  Quality Alert for fine particle pollution. The Air Quality
  Index (AQI) is expected to reach the Purple or Very Unhealthy
  category. This will be a long duration and unprecedented
  significant air quality event for Minnesota.

* WHERE...Central and south central Minnesota.

* WHEN...Through 3 PM CDT Tuesday.

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

* ADDITIONAL DETAILS...Smoke from Canadian wildfires lingers over
  most of Minnesota. There will be some slight improvement in air
  quality throughout Friday and Friday night. However, on
  Saturday northerly winds behind a cold front will bring more
  smoke from wildfires located north of the Canadian border in
  Ontario and Manitoba into Minnesota. This reinforcing batch of
  heavy smoke is expected to arrive starting Saturday morning.
  Smoke will continue pouring into the state throughout Saturday
  and into Sunday. High pressure will build over the area for
  Sunday and remain over the area for Monday into Tuesday morning.
  Smoke will recirculate under the high pressure, leading to
  prolonged period of heavy smoke. Fine particle levels will begin
  to improve Tuesday as southerly winds start moving the smoke
  out of the state. Fine particle levels are expected to reach the
  Purple AQI category, a level considered very unhealthy for
  everyone, across north central and south central Minnesota. This
  area includes St Cloud, the Twin Cities, and the tribal nation
  of Mille Lacs. Fine particle levels are expected to reach the
  Red AQI category, a level considered unhealthy for everyone,
  across northern and central Minnesota. This area includes
  Alexandria, Mankato, Albert Lea, and the tribal nations of Upper
  Sioux and Prairie Island.

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.
