A powerful atmospheric river storm that struck California helped set rainfall records and put down wildfires. But it was not yet known how much dent it made in the state drought.


NS Meteorological system It weakened as it moved south, but it still rained enough on Monday evening, causing a landslide that closed the roads in the San Bernardino Mountains northeast of Rosansels.

An atmospheric river storm, a long, wide-humidity plume drawn from the Pacific Ocean, landed in Northern California over the weekend.

The pouring rain caused widespread floods and rock slips. A strong wind knocked down a tree and knocked down two heavy trucks at the Richmond-San Rafael Bridge near San Francisco. Pacific Gas & Electric reported that 646,000 homes and businesses had lost power, but most had lost power by Monday.

By the beginning of Tuesday, it was still raining and snowing in northern California. The remaining flood warning was in Sonoma County, north of San Francisco, where the stream was slowly dropping.

Despite the problems, rain and mountain snow were welcomed in Northern California. Northern California is so dry that almost everything falls into extreme or exceptional droughts.

NS Rainy weather It also significantly reduces the chances of an additional wildfire in an area in the state that has been blamed for another year’s devastating flames.

The National Meteorological Service has called the sum of preliminary rainfall from storms “amazing.” It fell 4 inches (10 centimeters) downtown San Francisco on Sunday, making it the fourth rainiest day in San Francisco.

“It’s been a memorable last 24 hours for the Bay Area, as the long-talked-about atmospheric rivers flowed through the area,” the local meteorological agency said on Monday. “We literally went from fire / drought to flood in one storm cycle.”

5.44 inches (13.82 centimeters) northeast of San Francisco fell downtown Sacramento, breaking the one-day record of rainfall that had been going on since 1880.

Approximately 5.4 inches (13.72 centimeters) of rain was recorded at California Polytechnic State University in San Luis Obispo County along the state’s central coast. In Southern California, 1.1 inches (2.79 centimeters) fell to Beverly Hills.

Interstate 80, Major highways The Sierra Nevada Mountains to Reno, Nevada were closed due to heavy snow early Monday. In California’s Colusa and Yolo counties, State Highways 16 and 20 were closed for miles due to landslides, the State Department said.

The same storm system also blamed Oregon and Washington, causing power outages affecting tens of thousands of people. Two people died when a tree fell into a car in the Seattle metropolitan area.

According to the State Department of Water Resources, the water level of Lake Oroville, Northern California’s main reservoir, has risen 20 feet (6.10 meters) in the past week. Most of the increase occurred between Saturday and Monday during the storm, KHSL-TV report.

Justin Mankin, a professor of geography at Dartmouth College and co-leader of the National Oceanic and Atmospheric Administration’s Drought Task Force, said climate change will continue the cycle of years of drought to record heavy rainfall. He said it was expected.

“This rain is welcome, but with these dangers it does not necessarily end the drought,” Mankin said. “California still needs more precipitation, and it really spreads over a longer period of time because it needs it at high altitudes and it’s not dangerous.”

Christie Brigam, head of resource management and science at Sequoia and Kings Canyon National Parks, said it rained after a Caldor fire burned an unknown number of giant trees in the park along with thousands of pine trees and cedars. Said a great relief.

“This rainfall is what we call the end-of-season event,” Brigham said. “It should end the season of fire, and it should end most of our need to fight this fire.”

The Caldor fire continued to burn for more than two months, prompting an unprecedented evacuation of the entire city of South Lake Tahoe, a major tourist destination, in early September. Firefighters have come to consider the fire to be completely contained. This status also applies to the second largest Dixie fire in state history, just under 1,563 square miles (4,048 square kilometers).

Over the weekend, the California Highway Patrol closed State Highway 70 in Butte County and Plumas County. This is due to multiple landslides occurring within the burn scars of a large Dixie Fire.

The state fire department, CalFire, did not declare the end of the wildfire season or reduce personnel to lower winter levels.

“I want to see a little more rain before considering headcount reductions,” said spokesman Isaac Sanchez.

California’s long-term weather forecasts suggest that it is drier than usual, Mankin said.

“To end the various aspects of the drought, we’ll need a situation where parts of California will get about 200% of normal rainfall over the next three months,” he said. Despite the truly unusual rainfall, winter will probably be drier than average. ”


After the drought, the west coast of the United States was hit by a “bomb low pressure”
