The Pima County Department of Environmental Quality is issuing an air quality advisory due to the potential for elevated levels of particulate matter this afternoon and tonight.
The dry conditions and winds are causing higher than normal levels of airborne particulate matter today and wind gusts are predicted to be as high as 34 miles per hour tonight and 47 m.p.h. tomorrow afternoon.
Particulate matter is made up of tiny specks of soot, dust, and aerosols that are suspended in the air we breathe.
Individuals with heart disease and respiratory sensitivities may wish to reduce exposure to outside air this afternoon and tonight. And if you need to go outside, it is suggested you reduce your level of exertion to decrease the amount of particulates you breathe into your lungs.
This advisory will be in effect as long as current weather conditions continue.
