Air Quality Alert issued July 19 at 9:01AM EDT by NWS Northern Indiana

Effective: Sun July 19, 2026, 9:01 AM
Expires: Tue July 21, 2026, 12:15 AM

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Alert for Sunday and Monday, July 19 and 20, for elevated levels of fine particulate (PM2.5) in parts of southwest 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. Another smoke plume has settled over the region due to wildfires in Canada. It is expected that the increased pollution will continue into Monday; however, levels will improve during the day as winds shift to a southerly direction. With smoke lingering across the state, ozone also has the potential to increase quickly. 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.
