920 AM CDT Thu Jul 16 2026

The Wisconsin Department of Natural Resources has issued an Air
Quality Advisory for the following counties: Ashland, Bayfield,
Burnett, Douglas, Iron, Price, Sawyer, and Washburn.

* WHAT...The PM2.5 AQI is expected to reach the Unhealthy (Red)
to Hazardous (Maroon) level.

* WHERE...Statewide.

* WHEN...Until noon Friday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups: Stay indoors and keep activity levels light.
Follow tips for keeping particle levels low indoors.

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.

Everyone: Avoid all physical activity outdoors.

Additional Details:

As of 7 a.m. Thursday morning, widespread Very Unhealthy (Purple)
to Hazardous (Maroon) AQI PM2.5 is being observed nearly
statewide. Surface analysis at 4 a.m. placed the boundary from
approximately Prairie du Chien to Platteville, with cleaner air
to the south and west of this boundary in portions of Grant,
Lafayette, and Crawford Counties. Although this boundary may
meander to the northeast from roughly 9 a.m. to 6 p.m. today and
bring cleaner air further into far southwest Wisconsin, the
boundary is then likely to sag back southwest overnight into
Friday morning. We then expect to see clearing of the smoke from
west to east throughout the day on Friday as southerly winds pick
up ahead of an approaching system. Given this setup, we are going
to extend the statewide air quality advisory until noon Friday.
At that time, it will be possible that we will extend the
advisory once again for eastern areas, especially those impacted
by Lake Michigan. It is also possible that areas along Lake
Superior will see prolonged smoke impacts and need to remain in
the advisory. However, we expect to remove much of the state from
the advisory area at that time for this first round of smoke.
