The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Alert for Wednesday, July 15th, for elevated levels of fine particulate (PM2.5) due to wildfire smoke in parts of southern Lower Michigan. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Alert is in effect for the following counties in southwest Michigan... Berrien, Cass, St Joseph, Branch, and Hillsdale Plumes of smoke from Canadian wildfires are expected to move into the region this week. Models are showing the smoke plumes will continue along the Michigan/ Indiana border on Wednesday. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, such as: * outdoor burning, * use of residential wood burning devices. Tips for households: Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.

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.
