The Wisconsin Department of Natural Resources has issued an Air
Quality Advisory for the following counties: Brown, Door, Florence,
Forest, Kewaunee, Langlade, Lincoln, Marathon, Marinette, Menominee,
Oconto, Oneida, Outagamie, Portage, Shawano, Vilas, Waupaca,
Waushara, and Wood.

WHAT...The PM2.5 AQI is expected to reach the Unhealthy for
Sensitive Groups (Orange) to Unhealthy (Red) level.

WHERE...Northern Wisconsin and west-central Wisconsin.

WHEN...From 10 AM Monday until 3 PM Tuesday.

Precautionary/Preparedness Actions:
Sensitive groups: Make outdoor activities shorter and less
intense. It is OK to be active outdoors but take more breaks.
Watch for symptoms such as coughing or shortness of breath.

People with asthma: Follow your asthma action plan and keep quick
relief medicine handy.

People with heart disease: Symptoms such as palpitations,
shortness of breath, or unusual fatigue may indicate a serious
problem. If you have any of these, contact your health care
provider.

Additional Details:
Canadian wildfire smoke will impact surface air quality as it
moves ENE across northern portions of the state through early
Tuesday afternoon. The heaviest smoke impacts are expected in far
northwest Wisconsin, where PM2.5 NowCast AQI values of Unhealthy
(Red) will be possible. Lesser impacts in the Moderate (Yellow) to
Unhealthy for Sensitive Groups (Orange) AQI range are expected
further south and east in the advisory area.

A cold front moving in from the northwest on Tuesday morning will
begin to clear this initial round of smoke from northwest to
southeast. Although more smoke could move in behind the front, we
do not expect advisory criteria to be met with the second round of
smoke at this time.
