Air Quality Alert
Issued: 3:33 PM CDT Aug. 16, 2018 – National Weather Service

... Air quality alert in effect from 3 PM today through 12 PM
Sunday...

The Minnesota pollution control agency has issued an air quality
alert for fine particle pollution for central 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 and eventually central
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. The southern half
of Minnesota will be monitored for an air quality alert Friday night
into Saturday.

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.
