...AIR QUALITY ALERT IN EFFECT FROM 12 AM CDT THURSDAY UNTIL 11 PM
CDT FRIDAY...

* 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 Orange or Unhealthy for Sensitive
Groups category.

* WHERE...Southwest Minnesota.

* WHEN...From 12 AM CDT Thursday until 11 PM CDT Friday.

* IMPACTS...Sensitive groups, such as people with lung disease
(including asthma), heart disease, and children and older adults, may
experience health effects.

* ADDITIONAL DETAILS...A band of heavy smoke from wildfires in
Saskatchewan and Manitoba is moving south across northwest Minnesota
on Wednesday. The smoke will remain over the northwest part of the
state through the end of Wednesday, but by Thursday morning the smoke
will reach southwest MN. Smoke will also move into the northeast and
central portions of the state Thursday morning, and by Thursday
afternoon smoke will reach east central and south central MN. Some
uncertainty still remains regarding how far south the ground-level
smoke will reach by Friday morning, when winds are expected to become
southerly and push the smoke back to the north. Air quality should
improve gradually from south to north beginning Friday afternoon,
with improvement in fine particle levels below the alert threshold
expected by the end of Friday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...Sensitive groups, such as
people with lung disease (including asthma), heart disease, and
children and older adults, 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.
