Air Quality Alert
Issued: 12:03 PM CDT Aug. 17, 2018 – National Weather Service

... Air quality alert in effect from 8 PM tonight through 12 PM
Sunday...

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

Canadian wildfire smoke originating from British Columbia, Alberta,
and western Ontario will continue to affect Minnesota Friday
afternoon and evening as it moves from north to south across the
state. Air pollution monitors show a rapid rise in fine particles
with values approaching an air quality index (aqi) value of 101
(orange) in northern Minnesota. This plume of smoke over northern
Minnesota is expected to move south during the day. Waves of smoke
will move over the state with air quality beginning to be impacted
in the St. Cloud to Twin Cities area by Saturday morning and Mankato
by the afternoon hours. 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 Sunday afternoon winds
will switch to the south improving air quality conditions.

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.
