The Illinois Environmental Protection Agency has issued an Areawide Air Pollution Action Day for today for portions of Illinois. This is in addition to the ongoing Areawide Air Pollution Action Day issued yesterday for the same areas. 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. AQI Category Guidance Unhealthy for Sensitive Groups (USG) - Members of sensitive groups may experience health effects. The general public is less likely to be affected. 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. Unhealthy - Sensitive groups: Avoid long or intense outdoor activities. Consider rescheduling or moving activities indoors. Everyone else: Reduce long or intense activities. Take more breaks during outdoor activities. Air quality forecasts and current air quality can be found at www.airnow.gov Media Contact... Illinois EPA

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
