SAN FRANCISCO – A forecast of at least one more day of hot temperatures and poor air quality has prompted air quality officials to issue another “Spare the Air” advisory for the Bay Area.

Because the air quality is expected to be unhealthy with high ozone levels, the Bay Area Air Quality Management District is urging the public to cut down on driving Friday.

It's the second day in a row the district has issued the advisory.

The worst smog is expected in eastern and central Contra Costa and Alameda counties from Martinez to Sunol, and in Benicia and Suisun City in Solano County.

The National Weather Service is predicting record highs are possible throughout the region.

Martinez is expected to see a high of 98 degrees, with Oakland topping off at 90.
