The Arizona Department of Environmental Quality has issued its first ozone high-pollution advisory of the year for the Phoenix metropolitan area for the rest of Friday.
An ozone health watch had already been issued for Friday, but the health warning was upgraded because six Valley monitors exceeded the ozone health standard on Thursday, the ADEQ said.
Yuma also had its highest ozone concentrations on Thursday in 10 years and those conditions are currently moving east into the Valley, ADEQ said. Ozone concentrations are expected to be much less on Saturday.
ADEQ recommended that children and adults with respiratory problems avoid outdoor activities the remainder of Friday and also suggests that the general public limit outdoor activity.
The Maricopa County Air Quality Department will enforce its mandatory "No Burn Day" restriction Friday. The restriction includes individuals and businesses that have burn permits for open burning.
Valley Metro asked that employers activate their HPA Plan. Residents and employers are asked to use these tips to help make the air healthier to breathe:
