The Minnesota pollution control agency has issued an air quality
alert for fine particle pollution for north central and northeastern
Minnesota.

A large area of Canadian wildfire smoke is moving into far northwest
Minnesota and will move south and east covering much of the northern
half of the state by early Friday morning. Air pollution monitors
show a rapid rise in fine particles with values exceeding an air
quality index (aqi) value of 100 along with weather observations
showing visibilities dropping to 2-5 miles in this plume of smoke
and expected to continue over northern Minnesota. The smoke plume is
from fires in British Columbia and Alberta and from wildfires north
of Kenora in western Ontario. Periods of smoke are expected to
persist in this area through Sunday morning. During this time, fine
particle pollution is expected to remain at, or above, a level that
is considered unhealthy for sensitive groups. By Saturday afternoon
winds will begin to decrease the transport of smoke into the
affected region.

An air quality alert is issued when the aqi is expected to reach or
exceed 101, a level considered unhealthy for sensitive groups.
Sensitive groups, such as people with lung disease (including
asthma), heart disease, children and older adults, and people who
are active outdoors should limit prolonged exertion.
