The Michigan Department of Environmental Quality has extended the Air Quality Advisory through Tuesday August 5, for elevated levels of fine particulates (PM2.5). Pollutants are expected to be in the Unhealthy for Sensitive Groups range. The alert is in effect for all Michigan counties. Any hopes that Monday morning would yield clearer skies were dashed when a quick peek outside shows the same haziness that has plagued the region for several days. As of mid-morning on Monday, nearly every monitor in the state is registering at least USG conditions with some reaching Unhealthy hourly readings. The main culprit remains Canadian wildfire smoke, originating from the Manitoba and Ontario Provinces. The second culprit is a stubborn high-pressure cell planted over the Midwest which is holding the smoke in place and compressing it close to the ground. The weak clockwise winds will recirculate the worst of the smoke westward then northward, back into the western U.P., but the entire state will remain under hazy conditions during Tuesday. As a result, we will be maintaining the state-wide Air Quality Advisory through Tuesday. Models are indicating that as the high-pressure cell slowly exits the region, Wednesday should be clean enough to end the advisories. 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 and 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.
