Air Quality Alert
The Wisconsin Department of Natural Resources has issued an Air
Quality Advisory for the following counties:
Columbia, Dane, Dodge, Fond du Lac, Green, Green Lake, Iowa,
Jefferson, Kenosha, Lafayette, Marquette, Milwaukee, Ozaukee,
Racine, Rock, Sauk, Sheboygan, Walworth, Washington, Waukesha.
WHAT...The PM2.5 AQI is expected to reach the Unhealthy for
Sensitive Groups level.
WHERE...All of Wisconsin
WHEN...6 am Friday, May 30 until 6 am Saturday, May 31
Precautionary/Preparedness Actions:
Sensitive groups: Make outdoor activities shorter and less
intense. It's 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:
Air quality will degrade from north to south on Friday as
Canadian wildfire smoke pushes in ahead of a cold front.
Unhealthy for Sensitive Groups (USG) AQI (Orange category) is
expected for much of the state, with the potential to reach
Unhealthy AQI (Red category). Areas to the southwest (mostly
along the Mississippi River valley) will have the best chance to
remain in Moderate AQI on Friday. The front will move into
northeast Wisconsin Friday evening and begin clearing the air
from northeast to southwest. However, this will also push smoke
further south and west, and an additional Air Quality Advisory
may be needed on Saturday for western areas if
PM2.5 concentrations remain high enough.
