Floods in Northern California are forcing thousands of people to evacuateby Circa News

Floods in Northern California threaten the homes of thousands of people as historic heavy rain barraged the region, with more expected on Wednesday.

The Cosumnes River in Sacramento County was expected to overflow, flooding roads and buildings with up to a foot of water. But some locals insisted they would stay. 

"We have no concerns," Lill Nichols told the Sacramento Bee. "We have animals and can't evacuate anyway."

"I think it's going to go higher. There's nowhere for this water to go."

The rainstorm on Tuesday is the latest in back-to-back systems that have brought the heaviest rain in a decade to parts of Northern California and Nevada. 

The storms are part of an “atmospheric river” weather phenomenon that draws precipitation from the Pacific Ocean as far west as Hawaii. Its impact can be catastrophic.

Meanwhile, over the Sierra Nevada Mountains, a blizzard warning was in effect that could dump up to 10 feet of snow in the highest mountains.  Many ski resorts shut down Tuesday because of the storm, and many major roads were either closed or required chains on tires.
