Salinas (United States) (AFP) - US President Joe Biden has declared a major disaster in California, as the latest in a succession of storm systems blew into the state, bringing heavy flooding to already waterlogged regions.
"Waves of heavy precipitation continue to batter California," said the National Weather Service (NWS) on Twitter.
"Heavy rain will continue bringing the threat of flooding and mudslides/landslides. Hazardous travel due to heavy mountain snow and blowing snow from (California) to (Colorado)."
Much of the town of Felton in the north of the state was under water Saturday, as it had been on New Year's Day and again Monday.
"I'm so angry, it just makes me want to cry," said Camilla Shaffer, a Briton whose house flooded for the third time in two weeks.
Amberlee Galvin, a chef at a local restaurant, was another victim, her front room entirely inundated.
"Within 10 minutes it had flooded completely to the ceiling. It happened crazy fast," the 23-year-old said. "We had to get canoed out by a neighbor."
"I hope this isn't the new normal," sighed Melissa Foley, pushing a wheelbarrow full of cleaning kits donated by the Red Cross, which she distributes to her neighbors.
Late Saturday, Biden "declared that a major disaster exists in the State of California and ordered Federal aid to supplement State, tribal, and local recovery efforts in the areas affected by severe winter storms, flooding, landslides, and mudslides," the White House said in a statement.
The declaration makes federal funding available for relief to affected people, including temporary housing and repairs.
At least 19 people are known to have died from storm-related causes in the last three weeks.

An AFP journalist saw the Salinas River overflowing its banks in many spots, at times covering farm fields for hundreds of yards, as rain continued under leaden skies.
In Spreckels, a community a few hundred yards from the river, most residents opted not to evacuate despite warnings from authorities.
"It looks like we might have missed kind of the worst of it," said Robert Zagajeski, out walking his dog under a light rain.
But Governor Gavin Newsom warned Californians that they were not in the clear yet: "We're not done," he said Saturday after visiting impacted residents.
Urging them to remain vigilant, he said Californians should continue to exercise "common sense over the course of the next 24 to 48 hours."
Nearly 26 million Californians remained under a flood watch Saturday evening, according to the NWS, with tens of thousands under evacuation orders and advisories.
The storms of recent weeks were originally welcomed -- coming after years of drought -- but by now have brought disastrous flooding, officials have said.

"This place was hit hard by the drought over the past years," 58-year-old farm worker Manuel Paris told AFP near Salinas. "We're not used to this much rain anymore."
The NWS said another two to three inches of rain (5.0 to 7.5 centimeters) could cause new flooding and mudslides, with parts of the Sierra Nevada seeing three to six feet of snow, and heavy winds buffeting central and coastal California at up to 50 miles (80 kilometers) per hour.

But on Saturday, an AFP journalist said the city itself had so far been largely spared.
Between storms, workers have rushed to clear some of the mess, shoveling mud from roads even in the heart of Los Angeles and using heavy machinery to remove fallen trees or clear rockslides.
