WHERE...All of Wisconsin

WHEN...Until noon Tuesday, August 5

Precautionary/Preparedness Actions:
Sensitive groups: Consider rescheduling or moving all activities
inside. Go inside if you have symptoms. 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 else: Keep outdoor activities shorter and less
intense. Go inside if you have symptoms.

Additional Details:
Canadian wildfire smoke will continue to impact surface air
quality in Wisconsin. Though significant improvements have been
observed over neighboring states yesterday into this morning, a
mix of Unhealthy for Sensitive Groups (USG; Orange) AQI and
Unhealthy (Red) AQI is forecast again today as smoke persists
over Wisconsin and continues to recirculate. The heaviest smoke
is expected across northeastern Wisconsin today, while lighter
impacts are more likely for southwestern counties. A few
locations may observe Moderate (Yellow) AQI, especially to the
southwest as a cleaner pocket of air is anticipated to move into
the state from the south. Conditions will continue to be
reevaluated on a day-to-day basis, including updates to the
forecast and any associated Air Quality Advisories.
