Special Statement, Air Quality Alert
Issued: 12:03 PM CST Dec. 12, 2018 – National Weather Service

... Fog and some patchy freezing drizzle to persist through the
early afternoon...

Areas of fog, with visibilities below 1 mile in places, are going
to persist through the early afternoon hours. The thicker of the
fog will mainly be across higher terrain areas.

Patchy freezing drizzle can also be expected with some of the
fog. The freezing drizzle could cause patchy icing on untreated
roads and sidewalks.

If traveling early this afternoon, be prepared for reduced
visibilities due to the fog and the possibility of hard to see
slippery spots on untreated roads.

... Air quality alert in effect from this morning through 6 PM
Thursday...

the Minnesota pollution control agency has issued an air quality
alert for fine particle pollution for southeast Minnesota.

Fine particle levels have reached the Orange (unhealthy for sensitive
groups) category across southeast Minnesota. Light winds, fog, and a
strong inversion have resulted in poor dispersion and air pollutants
are accumulating and becoming trapped near the ground. Poor
dispersion conditions will continue over the next couple of days
southeast Minnesota. Fine particle levels in the alert area are
expected to remain near or above 100 aqi until Thursday afternoon,
when a front moves across the state and brings cleaner air into the
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.
