GUERNEVILLE, Calif. - Northern California residents braced for a second storm to hit the region Sunday, a day after the first sent rivers rising into cities and mud sliding into homes and across highways.

One man died Saturday when a storm-weakened eucalyptus tree fell on him, a woman suffered a broken leg when a mudslide destroyed her Santa Rosa home, and more than half a dozen people were rescued from rushing water.

The Russian River crested early Sunday near the Sonoma County town of Guerneville at 42 feet — 10 feet above flood stage — flooding low-lying areas of the city and an unknown number of homes but sparing the downtown area, said Linda Eubanks of Sonoma County's Office of Emergency Services.

The extent of the damage was unclear because crews could not get into the affected area, she said.

Officials had urged residents of lower areas to evacuate and about 50 people were camped out in three local shelters, Eubanks said.

Many people chose to remain and ring in the New Year.

Maureen Weinstein hosted 10 friends and family members outside her Guerneville home, where they shot off fireworks, drank wine and listened to Motown.

"We live through (floods) a lot," Weinstein said, as the muddy river water hovered 10 feet away. "We're not that concerned this time because this year we have power and the Internet. I can monitor the water. It's wonderful."

The storm dumped an average of 4 to 5 inches in Northern California, with parts of Marin County recording more than 7 inches, according to the National Weather Service.

Sunday's storm was expected to drop another 2 inches in Northern California, up to 4 inches in Southern California's coastal valley and 8 inches in the mountains, forecasters said. Rain was expected to resume Sunday afternoon.

"It's looking pretty powerful," said NWS weather specialist Bonnie Bartling.

It also threatened to rain on Monday's Rose Parade in Pasedena for the first time since 1955.

On Saturday, at least six helicopter rescues were performed Saturday in Sonoma County. Firefighters rescued two people from a mobile home park, where 4 feet of rushing water washed at least one house off its foundation, fire officials said.

In the city of Napa, near the heart of wine country, the Napa River rose 5 feet above flood stage, sending a surge of water to several blocks of downtown.

"We had so much water in such a short amount of time that manhole covers were popping all over the city," city councilman James Krider said.

Upstream in St. Helena, the Napa River reached a record 7 feet above flood stage before beginning to recede late Saturday. About 1,000 homes flooded, officials estimated.

In San Anselmo, the creek poured into as many as 70 downtown businesses, and two people rescued from the rising water were hospitalized with hypothermia, town administrator Debbie Stutsman said.

"The entire downtown area was under 4 1/2 feet of water," Stutsman said.

More than 600,000 Pacific Gas and Electric Co. customers from Bakersfield to the Oregon border experienced power outages, spokeswoman Claudia Mendoza said. About 110,000 customers remained without service early Sunday.

Mudslides closed several major roads, including Interstate 80 in the Sierra Nevada about 25 miles west of Reno. Six tractor-trailer rigs were caught in one slide on I-80 early Saturday, but no injuries were reported.

The interstate, the major corridor linking Northern California and points east, was expected to remain closed for at least two days, state officials said.
