SAN FRANCISCO (AP) — A power outage struck a wide area of San Francisco on Friday, blacking out about 90,000 utility customers, trapping people in stuck elevators, snarling traffic as intersection signals went dark and forcing shops and restaurants to close. Pacific Gas & Electric crews were assessing the problem and there was no immediate estimate for restoration of electricity. The Fire Department tweeted that it had responded to more than 100 calls for service, including 20 stuck elevators with people inside. However, no injuries were reported related to the outage.
