A deadly storm dropped record-breaking rain and snow along its coastline, causing widespread damage in northern California.
Landslides, sinkholes and flooding were reported across the region as massive waves swept the walls of homes.
Two deaths were reported on Thursday. A toddler died after a tree fell on her house, and a 19-year-old woman died after being hit by her car from wet roads.
The forecast is for more ominous weather for the weekend and next week.
As of Friday morning, more than 97,000 homes and businesses were without power after hurricane-force winds knocked down large trees and knocked down power cables.
While San Francisco’s neighborhoods are still recovering from flooding, forecasters say wetter and windier weather is coming to the area.
It rained in areas that were saturated from the New Year’s Eve storm.
A resident of the Cambria beach community in San Luis Obispo County was hit by an “extremely large rogue wave” inside their home on Thursday morning.
“The house’s beach windows were smashed and toppled by the calm, powerful wave,” the Cambria Fire Department said, adding that “water damage has spread throughout the house.”
Homes were also damaged in Monterey County and Humboldt County, where officials in the town of Shelter Cove warned that waves could “easily drag people and pets into the ocean.”
Parts of the Capitola pier in Santa Cruz County collapsed under waves 35 feet (10.6 meters).
Tony Valdez, who has lived in Santa Cruz for 28 years, said he felt “not believing” when he saw the damage to the pier.
“So, it had to take a big hit for this damage,” the BBC’s US partner told CBS News. “So you have to have a lot of respect for the ocean and the water there.”
Capitola restaurant owner Joshua Kochanek said the waves hit his business about every 10 minutes.
“The waves were coming and all the damage. It was terrible. It kept you afloat,” he said.
Emergency shelters have been opened for residents who have been told to evacuate their homes due to fears of floods and landslides on the slopes caused by recent forest fires.
Beaches along the coast were also ordered to be closed.
Further inland, more than a foot of heavy snow has accumulated in the Sierra Nevada mountains and more is expected.
The mountains are expected to receive up to three meters of additional snow in the coming days, according to the National Weather Service.
A “stronger” atmospheric river is expected to arrive on Monday and continue through Tuesday, bringing more precipitation and strong winds.
