Update: This story has been updated to include how soon the power is expected to be fully restored by Southern California Edison. Roughly 45 residents in Newhall are still experiencing a power outage following an unknown interference, causing an automatic shutdown of their power Saturday morning, Southern California Edison officials said. The outage was first reported at around 11:21 a.m., initially affecting 3,600 residents, according to Edison spokesperson Mary Ann Milbourn. Early reports for the outage originated around Lyons Avenue and Lola Lane in Newhall. By 11:34 a.m., power was restored to 3,000 residents, leaving hundreds of Edison users still without power, Milbourn said at 12:01 p.m. Power returned to over 500 users at around 1:30 p.m., she later said. The cause of the power outage is still unknown, but it affected an underground cable wiring around Lyons Avenue and Lola Lane, Milbourn said. Because it’s underground, there is more difficulty for Edison technicians to reach the cable, she said. A full restoration is expected by 8 p.m.-9 p.m., Milbourn said.
