The Pima County Department of Environmental Quality (PDEQ) has issued an Air Quality Health Watch for December 3, 2020, triggered by prolonged hours of high winds. Some of the PDEQ air quality monitors that measure particulate matter are currently in the “moderate” range, but areas that are dust-prone may be experiencing higher levels of particulate matter. Winds are forecasted to continue through this afternoon and these wind-blown particles could stay airborne for a while.
