San Francisco — A recent fire-burnt area in northern California was flooded with highways, collapsed trees, and lahars, followed by a strong storm towards Southern California.
With the arrival of the atmospheric river on the weekend, there was a shower and strong winds. A long, wide-humidity eruption drawn from the Pacific Ocean. The National Weather Service’s Sacramento office has warned of “potentially historic rain.”
Floods were reported throughout the San Francisco Bay Area, Berkeley roads were closed, Oakland’s Baybridge tollhouse was flooded, and rivers in Napa and Sonoma counties were flooded. A utility pole collapsed and tens of thousands of people in North Bay lost electricity.
By Sunday morning, Mount Tamalpais, just north of San Francisco, had recorded 0.5 feet (15 centimeters) of rainfall in the last 12 hours, according to the Meteorological Agency.
“In some of our high altitude areas, it is possible that it will rain 6, 7, or 8 inches before we are all told and completed,” said Meteorologist Sean Miller of Meteorological Services. rice field.
The California Highway Patrol has closed State Highway 70 in Butte and Plumas County, about 150 miles north. This was due to multiple landslides within the burn scars of a large Dixie fire.
“There have already been several collisions this morning on some roads with hydroplaning of vehicles, numerous tree falls and floods,” the Oroville highway patrol office tweeted on Sunday. “If you can stay home and get off the road today, do so. If you’re on the go, be very careful.”
The same storm system has 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. Eastside Fire & Rescue responded to the dead scene near Preston, Washington, about 20 miles east of Seattle.
In California’s Colusa and Yolo counties, State Highways 16 and 20 were closed for miles due to landslides, the State Department said.
Burned areas remain a concern, as vegetation-free lands cannot absorb heavy rains quickly and flash floods are more likely to occur.
“If you’re near a recent burn and haven’t been there yet, be prepared for a possible debris flow,” the Sacramento Meteorological Department tweeted. “If a local official tells you to evacuate or feels threatened, feel free to do so. If it’s too late to evacuate, you’ll reach a hill.”
In southern San Francisco, evacuation orders came into force in the Santa Cruz Mountains because of concerns that a few inches of rain could cause debris flow in the burn scars of the CZU Lightning Complex when a storm passes early Monday. Further south, in parts of western Santa Barbara County, evacuation alerts have been upgraded to orders in areas burned down by the Alisal fire this month.
Strong winds with gusts of up to 60 mph were also expected in the windiest areas of Northern California. At altitudes above 9,000 feet in the Sierra Nevada, it can snow more than 18 inches from Sunday to Monday morning.
Recent storms have helped contain some of the country’s largest wildfires this year. But it’s still unclear if rain will make a dent in the drought that plagues California and the western United States. California’s climate is hotter and drier, which means that rain and snow are more likely to evaporate or be absorbed by the soil.
California’s 2021 water year, which ended on September 30, was the second driest on record and the fifth driest on record last year. Some of the state’s most important reservoirs are at record low levels.
