LOS ANGELES (AP) – Southern California utilities say they may cut power to more than 300,000 customers this week as dry, gusty weather raises the threat of wildfire danger. The National Weather Service is issuing red flag warnings of extreme fire danger over much of the region because of dry vegetation, low humidity and gusty Santa Ana winds. The winds can knock down power lines and spark blazes. Southern California Edison says it’s considering cutting power to nearly 237,000 customers as a precaution, possibly beginning Wednesday evening and running into the weekend. San Diego Gas & Electric says 88,720 customers could see days-long shutoffs.
