The Illinois Environmental Protection Agency has declared an Air Pollution Action Day for the greater Chicago Metropolitan Area, which is IN EFFECT UNTIL MIDNIGHT CDT THURSDAY NIGHT. A Chicago area "Air Pollution Action Day" is declared when weather conditions are such that widespread ozone and or particulate levels are expected to be at or above the Unhealthy for Sensitive Groups (USG) category of the Air Quality Index for multiple days. Wildfire smoke is expected to continue to have an impact on particulate levels with the daily 24-hour AQI forecast expected to remain in the USG category today and tomorrow. Active children and adults, especially people with pulmonary or respiratory disease such as asthma, should limit prolonged outdoor activity. Area residents are urged to reduce pollution levels.

WHAT...The PM2.5 AQI is expected to reach the Unhealthy level. WHERE...Southern and eastern Wisconsin. WHEN...From noon Wednesday through noon Thursday. 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: Improving air quality is expected to move into Wisconsin from the northwest on Wednesday. However, smoke will continue to impact surface air quality across southern and eastern Wisconsin. Unhealthy AQI is most likely in eastern areas near the Green Bay and Lake Michigan water bodies. Unhealthy for Sensitive Groups AQI is more likely for western portions of the advisory area. For more information on current air quality, please see: https://airquality.wi.gov
