The Arizona Department of Environmental Quality has extended an Ozone High Pollution Advisory for the Phoenix metro area through Friday, July 3, the National Weather Service said in an alert issued at 8:18 a.m. Thursday.
Forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk, according to the NWS. Adverse health effects increase as air quality deteriorates.
Ozone is an air contaminant that can cause breathing difficulties for children, older adults, and people with respiratory problems. A decrease in physical activity is recommended for those groups.
Residents are urged to carpool, telecommute, or use mass transit. Use of gasoline-powered equipment should be reduced or deferred until late in the day.
The advisory is effective through 9 p.m. Friday. For current conditions and forecast details, ADEQ's Phoenix air quality page is at azdeq.gov/forecast/phoenix or by phone at 602-771-2300.
