Barrel storm heading south California On Monday, after flooding the highway, it knocked down trees in a wildfire-burned area in the northern part of the state, causing rock slips and mudflow.
Rainfall and strong winds accompanied the arrival of a drought-stricken river in the atmosphere (a long, humid eruption of the Pacific Ocean).
Rain records were shattered and heavy snow struck the highlands of the Sierra Nevada Mountains. The National Weather Service (NWS) struck the state with flash flood warnings.
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.
“In the Bay Area, the last 24 hours have been memorable, as the long-talked-about atmospheric rivers flowed through the area,” said the local meteorological agency. “We literally left the fire [and] A single storm cycle causes a drought to flood. “
The NWS called the total reserve rainfall “amazing,” including 11 inches at the foot of Mount Tamalpais and 4.02 inches downtown San Francisco.
“Yesterday seems to have been the fourth wettest day in history for downtown San Francisco, where records date back to the gold rush year,” Service said.
California’s highway patrol has closed State Highway 70 in Butte and Plumas counties, about 150 miles north. This is due to multiple landslides occurring within the large Dixie burn scars.
“There have already been several collisions this morning on some roads with hydroplaning of vehicles, numerous tree falls and floods,” Oroville’s highway patrol office tweeted. .. “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 struck 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 were also expected, with gusts of up to 60 mph occurring 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 now hotter and drier. In other words, rain and snow that fall are easy to evaporate and are not easily 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.
