SAN FRANCISCO Residents of Northern California were hunkering down early Sunday as a powerful storm drenched the area with yet another round of pounding rain and strong winds.
The latest storm system moved into the region Saturday night and was expected to force several Northern California rivers over their banks.
The Napa River, north of San Francisco, a river with a history of flooding, was expected to top its banks some time Sunday afternoon.
The Russian River, another river that frequently floods was expected to flood near the Sonoma County community of Guerneville Monday morning.
To the south, forecasters say as much as one inch of rain per hour fell on parts of the Santa Cruz mountains early Sunday, prompting the National Weather Service to issue a flash flood warning for parts of Santa Cruz and Santa Clara counties.
