TUCSON - There's a reason for the hazy skies this afternoon.

According to the Arizona Department of Environmental Quality, a regional dust plume from California, Nevada and western Arizona was transported to our area early this morning. PDEQ monitors are also recording elevated levels of particulate matter. As a result, an Air Quality Advisory has been issued for Metro Tucson.

Skies gradually clear with daytime mixing and breezes, behind a departing cold front. 

Higher particulate levels might return in the morning hours as cold weather persists.

Unusually sensitive people, including individuals with heart disease and respiratory sensitivities, may want to consider reducing prolonged or heavy outdoor exertion to decrease the amount of particulates they breathe into their lungs. Those most at risk may feel better if they avoid outside exercise, stay inside as much as possible, and keep windows and doors closed to help reduce exposure to particulate matter.

With cold weather forecasted today and tomorrow, smoke from fireplace fires might become a concern. PDEQ reminds residents to avoid or reduce fireplace fires when possible, especially during periods of elevated air pollution levels, and to burn hard woods like oak, pecan or mesquite, which burn hotter and cleaner than softer woods such as pine.
