The Valley is back under a health watch Thursday for ozone.

Several days in the last week the Valley has seen increasing levels of ozone –- an invisible gas created when pollutants in the air are heated by the sun.

Thursday’s high temperatures could reach 107, according to forecast reports on

The Valley was also under a health watch July 5-10.

Vehicle use helps add to the possibility of ozone production in the Valley, but Arizona also receives some ozone that moves in from California.

A "health watch" means the highest concentration of pollution may approach the federal health standard. Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion during a health watch.

ADEQ also recommends that you:

• Avoid waiting in long drive-thru lines. Park your car and go inside.

• Unplug unused appliances.

• Fuel your vehicle after dark or during cooler evening hours.

• Connect your outdoor lights to a timer or use solar lighting.

To find a carpool or vanpool, visit or call (602) 253-5000.
