Air Quality Alert issued August 4 at 10:03AM MST by NWS Phoenix AZ
AQAPSR The Arizona Department of Environmental Quality (ADEQ) has issued a PM-10 High Pollution Advisory for the Phoenix Metro Area on Tuesday. 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. Adverse health effects increase as air quality deteriorates. Coarse particulate matter - also known as PM-10 - is an air contaminant that can aggravate heart and lung disease conditions, especially in older adults, children, and those with asthma. A decrease in physical activity is recommended. Consolidate your travel, stabilize loose soils, slow down or avoid travel on dirt roads, reduce or eliminate fireplace use, and avoid using gas-powered lawn equipment. For details on this High Pollution Advisory, visit the ADEQ internet site at www.azdeq.gov/forecast/phoenix or call 602-771-2300.
