A powerful and dangerous storm stormed the Bay Area on Sunday, knocking down trees and supply lines, leaving tens of thousands of people with power and getting evacuation orders in San Mateo and Santa Cruz counties amid the growing risk of flooding.

The storm “atmospheric river” soaked large parts of northern California with 3 to 6 inches of rain as it swung in from the Pacific Ocean, bringing with it severe gusts of wind that knocked down trees and left people throughout the Bay Area in the dark. Parts of North Bay received even more rain – up to 10 inches in one place.

Nearly 131,000 Pacific Gas & Electric customers in the Bay Area were without power from 2:15 p.m. Sunday, the utility said, with about 50,500 of those affected in Marin and Sonoma counties and 43,500 on the peninsula. About 21,700 of these customers were in East Bay.

Strong winds overturned a tractor trailer and a semi on the Richmond-San Rafael bridge Sunday afternoon, leaving two lanes closed, according to the California Highway Patrol. And to the east, a landslide closed parts of Highway 70 near Butterfly Valley Road, and falling rocks closed part of Old Donner Road between Truckee and the summit.

In Marin County, “extreme flooding” was reported in downtown San Rafael. “Many of the roadways are under 2 feet of water and are impassable or otherwise closed,” police warned. “Floods are expected to worsen due to yet another high tide in addition to precipitation levels from the atmospheric river.”

The flood caused evacuations in communities hard hit by forest fires in recent years, with authorities warning of mudslides and waste streams that could easily sweep people away if not avoided.

Evacuations have been ordered in several areas across several coastal zones in San Mateo and Santa Cruz counties, largely in anticipation of heavy rain later Sunday afternoon.
