SAN FRANCISCO (CBS SF/BCN) –More than 12,200 PG&E customers remained without power in the Bay Area as of Tuesday morning as a result of this weekend’s major storm that blew through the region, the utility said.

About 646,000 customers had outages at some point since the atmospheric river, combined with a so-called bomb cyclone, came to the Bay Area on Sunday, but crews have been making progress in restoring power, bringing the lights back on for about 12,000 more customers since 9 p.m. Monday, PG&E spokesman Jason King said.

The rain and wind created PG&E’s greatest storm-related service impact in October since 2009, according to the utility.
