1156 PM CDT Mon May 12 2025

...AIR QUALITY ALERT IN EFFECT THROUGH 3 PM CDT TUESDAY...

* WHAT...The Minnesota Pollution Control Agency has issued an Air
  Quality Alert for fine particle pollution. The Air Quality Index
  (AQI) is expected to reach the Orange or Unhealthy for Sensitive
  Groups category.

* WHERE...Portions of northeast Minnesota including northern St.
  Louis, central St. Louis, and Inland Lake and Cook counties.
  The areas most likely to experience smoke impacts include
  Brimson, Isabella, Babbitt, Ely, and portions of the Boundary
  Waters Canoe Area Wilderness.

* WHEN...Through 3 PM CDT Tuesday.

* IMPACTS...Sensitive groups, such as people with lung disease
  (including asthma), heart disease, and children and older
  adults, may experience health effects.

* ADDITIONAL DETAILS...The Camp House Fire, Jenkins Creek Fire,
  and Munger Shaw Fire are ongoing across northeastern Minnesota.
  Crews are responding with full suppression using ground
  resources and aircraft. Gusty southerly winds will become more
  southeasterly Tuesday. This will transport the smoke plume north
  and northeast from the ongoing fires. Smoke will continue to
  impact areas near and downwind of the fires. Smoke from these
  fires has been observed as far north as the Canadian Border.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
limit prolonged or heavy exertion.

Follow all safety instructions from local emergency management
officials. Evacuation orders issued for St. Louis County can be

...AIR QUALITY ALERT IN EFFECT FROM NOON CDT TO 9 PM CDT TUESDAY...

* WHAT...The Minnesota Pollution Control Agency has issued an Air
Quality Alert for ozone pollution. The Air Quality Index (AQI) is
expected to reach the Orange or Unhealthy for Sensitive Groups
category.

* WHERE...West central, east central, central, south central,
southwest, north central, and northwest Minnesota.

* WHEN...From noon CDT to 9 PM CDT Tuesday.

* IMPACTS...Sensitive groups, such as people with lung disease
(including asthma), heart disease, children and older adults, and
people who are active outdoors, may experience health effects.

* ADDITIONAL DETAILS...Ground-level ozone is expected to be high once
again during the afternoon hours on Tuesday across roughly the
western two-thirds of Minnesota, including the Twin Cities Metro.
Mostly sunny skies, warm temperatures and low humidity will provide a
favorable environment for two types of pollutants (volatile organic
compounds and nitrogen oxides) to react with sunlight in the air to
produce ground-level ozone. Ozone will remain elevated on Wednesday
as sunny skies, warm temperatures and dry conditions persist. This
alert for ground level ozone is in addition to the air quality alert
for wildfire smoke issued across portions of the Arrowhead.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 or heavy outdoor 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.
