shortness of breath, or unusual fatigue may indicate a serious
problem. If you have any of these, contact your health care
provider.

Everyone else: Keep outdoor activities shorter and less intense.
Go inside if you have symptoms.

Additional Details:
Canadian wildfire smoke will impact Wisconsin`s surface air
quality over the coming days, causing the PM2.5 Air Quality Index
(AQI) to range from the Unhealthy for Sensitive Groups (USG;
Orange) category to the Unhealthy (Red) category. It will be
possible for NowCast AQI values to reach the Very Unhealthy
(Purple) category.

Smoke impacts are already being observed in northern Wisconsin on
Tuesday morning, and the smoke is expected to slowly travel south
through northern Wisconsin Tuesday. Overnight Tuesday into
Wednesday morning, the smoke will continue south, impacting most
of the state by noon Wednesday. The smoke is then expected to
linger over the state from noon Wednesday until noon Thursday. We
may see brief improvements in air quality on Thursday before
smoke moves back into northern areas on Friday. Stay tuned to the
air quality forecast as conditions can change quickly during
wildfire smoke events.
