Heavy snow covered the Northern California mountains and rain and wind hit the US West Coast as a third day of winter storms left at least three people dead and hundreds of thousands of homes and businesses in California, Oregon and Washington without power.

A ruptured levee sent a freezing “wall of water” from a rain-swollen canal into the desert town of Fernley yesterday, flooding hundreds of homes and forcing the rescue of dozens of people by helicopter and boat.
No injuries were reported in the flood in the town about 30 miles east of Reno, after a section of the Truckee Canal levee up to 150 feet long broke early on Saturday.
Up to 3,500 people were temporarily stranded and an estimated 1,500 ended up being displaced from their homes. About 25 people remained at a shelter set up at a high school after a peak of about 150 earlier in the day.
Eric Cornett estimated the water was about 2 feet deep and rising fast when he drove away from his home with his wife and three children.
“We saw water coming in the back door and tried to grab as much stuff as possible to save it. The water was rising very quickly and it was scary,” he said.
Two helicopters aided crews in pontoons in rescuing at least 18 people from driveways and rooftops. Residents in fishing boats rescued many more.
By afternoon, the Truckee River water flowing into the canal was diverted upstream, said Ernie Schank, president of the Truckee-Carson Irrigation District. As the water receded, Fernley Mayor Todd Cutler said he had reports of damage to at least 300 to 400 homes.
One official suggested burrowing rodents might have contributed to the break in the levee along with the heavy rains, but the cause was not clear.
