The highest AQ index in Michigan (as of 17:00 EST) is currently the Detroit area. Particle Pollution (PM2.5) is measuring at 96 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Ann Arbor area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Surface temperatures reaching 50 degrees F have sped up snowmelt and are releasing particulates into the atmosphere in the process. Particulates get trapped in snow when it falls and when that snow melts, those same particulates get released into the air. Couple the warming temperatures with light winds throughout today, Sunday, PM-2.5 concentrations are expected to be in the Unhealthy for Sensitive Groups range due to lack of atmospheric dispersion. For clarity, this Advisory is not due to wildfire smoke, but organic compounds and other pollutants being trapped in snowfall that are being released into the air upon melting.
