SAN FRANCISCO (AP) — Residents of Northern California hunkered down Sunday as a powerful storm drenched the area with yet another round of pounding rain and strong winds.
The latest storm system — the third to hit the area in less than a week — moved across the region late Saturday and early Sunday dropping as much as an inch of rain per hour in some areas, toppling trees and knocking out electrical service to tens of thousands of people, officials said.

Flood warnings were in effect for the Napa and Russian rivers, two rivers north of San Francisco with a history of flooding, as well as the Truckee River, near Lake Tahoe.

In bracing for the storm, city officials had handed out more than 8,000 sandbags and about 150 tons of sand, Martin said.
The Napa River was expected to surpass flood stage Sunday afternoon, though most of the flooding was expected to be in agricultural areas outside of the city of Napa, officials said.
In Sonoma County, the Russian River was expected to top its banks Monday morning, forecasters said.
