An Areawide Air Pollution Action Day is declared when weather conditions are such that widespread ozone and or particulate levels are forecast to be at OR ABOVE the Unhealthy for Sensitive Groups (USG) category in all or nearly all Illinois AQI forecast sectors. Areas both inside and outside of the Action Day coverage area are likely to see smoke/PM2.5 to a varying degree and duration today and Monday with smoke likely decreasing from southwest to northeast through the day Monday. Those with air quality concerns or anyone in Illinois with outdoor plans are encouraged to check current NowCast readings or sign up for EnviroFlash alerts on AirNow. gov. Before going outside, checking the NowCast AQI will help identify periods of both poor and cleaner air quality regardless of the level of the daily 24-hour AQI forecast.

Sensitive groups: Make outdoor activities shorter and less intense. Its OK to be active outdoors, but take more breaks. Watch for symptoms such as coughing or shortness of breath. 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.
