The San Francisco Fire Department tweeted images of downed trees and flooded buildings on Saturday. San Francisco Public Works announced it could supply 10 sandbags per home and business in preparation for the wet weather over the weekend.

«This is a very large storm, very widespread impacts across much of the state that we expect Californians to be watching for over the next few days,» National Weather Service regional meteorologist Eric Schoening said at a state news conference Sunday. to become night.

Karla Nemeth, director of the California Department of Water Resources, said the storm that hit Sacramento on Sunday was the fifth of the season, with a sixth expected to hit the state on Thursday.

She described the storms as part of river weather events, fronts hatched in the Gulf of Alaska and fed by rainfall from the tropical Pacific.

«We are working in conditions of intense saturation,» Nemeth said at the press conference. «Even moderate levels of rainfall can produce significant flooding impacts.»

California Emergency Services Director Nancy Ward said flooding kills more people in California than any other natural disaster, including the state’s notorious wildfires.

The National Weather Service said in a bulletin Sunday that back-to-back storms could produce landslides, flash flooding and debris flows.

The west coast «remains under the target of a relentless parade of cyclones,» which will intensify over the Pacific Ocean as it moves inland, the NWS said.

Governor Gavin Newsom declared a state of emergency Wednesday as California was engulfed in rain and snow, causing flooding across the state. The declaration will allow local jurisdictions and state agencies to respond to the changing climate more quickly.

California’s soil has long been weakened by drought and summer wildfires, which cause trees to become brittle or burn. This reduces the amount of interference from rain, which quickly forms streams in parched ground and leads to increased risk of flooding.

Climate change has already made extreme precipitation in California twice as likely, with extreme weather predicted to generate 200-400% of surface runoff (rainwater that cannot be absorbed by the ground) for turn of the century, according to research conducted by the University of California at Los Angeles environment and sustainability department

Wade Crawford, the secretary of state for natural resources, told Sunday’s news conference that the weather in January has been «supercharged by climate change.»
