New evacuations were ordered Saturday for at least 50,000 people near a huge wildfire and millions of Californians will have their power cut again as the state’s largest utility said it would shut off electricity for the third time in as many weeks because of looming strong winds and high fire danger. Pacific Gas & Electric said it would begin blackouts in the afternoon for about 940,000 homes and businesses in 36 counties for 48 hours or longer throughout the San Francisco Bay Area, wine country and Sierra foothills. That’s about 90,000 more customers affected than previously predicted.
