La Crosse, Wisconsin, is bracing for a smoky and hot weekend as wildfire smoke from Canada drifts into the region. This, combined with high temperatures, will create an “Unhealthy for Sensitive Groups” air quality, which could affect health, especially for vulnerable individuals. The air quality advisory is set to last through Monday noon.
Health Risks and Air Quality Advisory
The Wisconsin Department of Natural Resources has issued an Air Quality Advisory due to elevated levels of PM2.5, the fine particulate matter in the air that is a result of wildfire smoke.
This advisory is particularly concerning for sensitive groups, including children, the elderly, and individuals with asthma or heart conditions. The air quality is expected to worsen on Sunday, with the highest concentrations of smoke affecting La Crosse and nearby areas like Sparta, Viroqua, and Prairie du Chien.
Despite the clear visibility, the invisible fine particles in the air can still be hazardous to health. Residents are advised to limit outdoor activities, especially strenuous exercise, and keep any necessary medications on hand.
Travelers along major highways such as Highway 35, I-90, and other local routes should also expect hazy conditions and potential breathing discomfort through the start of the week.
Sunny, But Hot Weather Ahead
Despite the smoke, Sunday’s weather in La Crosse will remain sunny with a high near 84°F and light winds from the southwest. As the weekend progresses, temperatures are expected to climb.
On Monday, the high could reach 88°F under mostly sunny skies, with warm conditions continuing into Tuesday. While rain chances are low, scattered thunderstorms could develop by Tuesday night and persist into Wednesday.
5-Day Outlook (July 13–17)
Sunday: Sunny, 84°F.
Monday: Mostly sunny, high 88°F.
Tuesday: Slight storm chance late, high 87°F.
Wednesday: Scattered thunderstorms likely, high 83°F.
Thursday: Spotty storms continue, high 78°F.
The air quality advisory remains in effect until noon on Monday, and more advisories may be issued if the wildfire smoke lingers.
Stay Safe and Prepare for Air Quality Issues
As smoky conditions continue, it’s essential for everyone, particularly those in sensitive groups, to stay indoors as much as possible. Keep an eye on air quality reports and adjust your plans accordingly.
If you must go outside, limit your physical exertion, and consider wearing a mask if necessary. With the smoke expected to continue, be prepared for possible air quality advisories throughout the week.
