The Arizona Department of Environmental Quality issued a PM-10 High Pollution Advisory for the Phoenix Metro Area through Saturday, Aug. 29 at 9 p.m., the National Weather Service announced Friday morning.
An episode of strong and gusty winds is forecast to generate widespread blowing dust that may result in local PM-10 concentrations that pose a health risk, according to the NWS alert issued at 11:18 a.m. MST. Adverse health effects increase as air quality deteriorates.
