La Crosse, Wisconsin – Smoke from Canadian wildfires is triggering poor air quality across western Wisconsin through midday Tuesday, with PM2.5 levels climbing to unhealthy ranges for sensitive groups, especially east of the Mississippi River. Residents in La Crosse, Richland Center, and Black River Falls may feel the effects as smoke continues to recirculate through the region.
According to the Wisconsin Department of Natural Resources, an Air Quality Advisory remains in effect for counties including La Crosse, Monroe, Jackson, Vernon, and Trempealeau. The advisory lasts until noon Tuesday, as surface smoke traps fine particulate matter near ground level. Those with asthma, heart conditions, or other sensitivities should avoid outdoor activity and monitor symptoms closely.
Light winds will allow smoke to persist into Tuesday morning before conditions begin to improve. A pocket of cleaner air is expected to push in from the south by early afternoon. However, storms could return by Wednesday night, bringing shifting wind patterns and a potential new round of air quality changes.

- Tuesday: Mostly sunny, high 83°F. Air quality improves by afternoon.
