PHOENIX (AP) -- An ozone health watch has been issued for Thursday in metropolitan Phoenix.

The watch was issued because pollution levels could approach the federal health standard for air quality. 

Environmental regulators say people who are unusually sensitive to air quality should consider limiting their time outdoors, because ozone can irritate the lungs and aggravate existing health conditions such as asthma.   

Authorities recommend that people avoid waiting in their cars at drive-thru restaurants, unplug electronic devices that aren't being used, unplug unused appliances and fuel their cars after dark or during cooler evening hours.
