...AIR QUALITY ALERT FROM 1 PM CDT SATURDAY UNTIL 9 AM CDT
MONDAY...

* 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 Purple or Very Unhealthy category.

* WHERE...North central, northeast, and northwest Minnesota.

* WHEN...1 PM CDT Saturday until 9 AM CDT Monday.

* IMPACTS...The risk of health effects is increased for everyone.

* ADDITIONAL DETAILS...Heavy surface smoke from Canadian
wildfires will drift south into Minnesota over the next several
days. This smoke will initially impact far northern Minnesota
early Saturday afternoon and then spread south and east through
the rest of the day and into the evening. Smoke lingers across
the region on Sunday with light winds in place, and then exits
back to the north through Monday morning. The highest smoke
concentrations are expected to be across far northern Minnesota
and the Arrowhead region from Saturday into Sunday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
avoid all physical activities outdoors. The general public should
avoid 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.
