Power is out throughout the downtown area from Marina Vista to Shell Ave. PG&E estimates the power will be back on around 5:30 pm.
City officials are cautioning people when driving through the city and to use caution at any uncontrolled intersections.
Traffic had been restored to all but a few customers in the area by 6 p.m. PG&E said the problem appears to have started in an underground equipment vault.
Court is adjourned.
