SAN DIEGO – The tail end of a powerful atmospheric river storm that knocked out power to hundreds of thousands of California homes and businesses will wreak havoc across the state Monday with more heavy rain, mudslides, flooding and several feet of snow on the mountains. I was hit by a flood.
As of Monday morning, the brunt of the storm’s fury was concentrated in the Los Angeles area, with 1.4 million people under flash flood warnings, including Hollywood Hills and Beverly Hills.
Across Southern California, the strong winds that hit the region on Sunday are weakening, but the National Weather Service warned that the unstable weather pattern could produce jets and small tornadoes.
Flash flooding is “a far greater threat than the weak tornadoes that storms can produce,” the Bureau of Meteorology said, adding that dangerous flooding is caused by atmospheric rivers (equivalent to the rivers in the sky that cause large swaths of the region). He said it was likely that the incident occurred in some areas. Be prepared for extreme rain and snow in the West.
An additional 5 to 8 inches of rain is expected in some areas, and the 48-hour rainfall total could reach 14 inches in some places, the weather service said. A state of emergency has been declared in eight Southern California counties.
“Life-threatening conditions could develop very quickly in some areas,” AccuWeather senior meteorologist Alex Sosnowski warned.
San Diego Mayor Todd Gloria issued an evacuation warning for low-lying, flood-prone areas that were damaged by heavy rains last week and flooded two weeks ago. Some areas on the city’s outskirts have received up to 7 inches of rain over the past two days.
“I understand that repeated warnings can be exhausting,” Gloria said. “We recognize that fatigue may be building, but we want to assure you that this decision to issue this warning is not taken lightly. We ask everyone to remain prepared and remain vigilant. Please have it.”
Developmental status:
∎ A debris flow caused significant damage to approximately five homes in Beverly Hills on Monday, the Los Angeles Fire Department announced. No one was trapped, but about 10 people were evacuated, LAFD said.
∎ More than 4 inches of rain was recorded in Los Angeles on Sunday, breaking the record for the day by more than 1 inch. This was the heaviest rainfall in a single day in more than 20 years and exceeded the average for February.
∎ The AT&T Pebble Beach Pro-Am Golf Tournament in Monterey County, which had postponed Sunday’s final round to Monday, was played on Monday even though only 54 holes of the scheduled 72-hole tournament were played. was canceled and Windham-Clark was declared the winner.
∎ A man was killed when strong winds toppled a redwood tree in Yuba City, 40 miles north of Sacramento, police said.

Where will the storm go next?
After hitting California on Monday, the storm’s moisture will bring heavy snow across the West, forecasters said, and the normally dry desert region of the Southwest will see heavy rain over the next few days. “Sporadic flash flooding is possible when precipitation totals are typically between 1 and 3 inches.” This was announced by the National Weather Service.
A flood watch was implemented for parts of southern Arizona and southern Nevada due to the risk of heavy rain and flooding.
Climate change and El Niño conspire to fuel storms
Multiple weather and climate phenomena conspire to make these storms especially damaging. Warm water provides energy for storms, and record sea temperature increases are being detected around the world, likely due to climate change. In addition, the effects of El Niño are also being felt in the Pacific Ocean, where trade winds weaken, reducing upwelling of ocean water and causing surface waters to become warmer as they are baked by the sun. And California, emerging from years of drought and wildfires, is especially vulnerable to landslides and flooding.
“Atmospheric River Fire Hose is Heading for Los Angeles.” tweeted Meteorologist Ryan Maue. “The onslaught from this dangerous bomb cyclone is just beginning.”
Wind gusts of 162 mph recorded in San Francisco Bay Area
In Northern California, the storm flooded roads and downed trees and power lines throughout the San Francisco Bay Area.rare Hurricane-force wind warning Winds exceeded 60 mph in the area, with gusts of up to 162 mph recorded in Marin County, making it a Category 2 hurricane.
In nearby San Jose, first responders went door to door to warn residents of the flooding threat and remove homeless people from riverbeds. They pulled tourists out of flooded car windows and rescued several people and a dog from an island in the Guadalupe River that had been engulfed by high water.
US weather warnings
The storm is the second in recent days after explosive conditions.
The storm hit California days after the first of the “Pineapple Express” storms drenched much of the state with up to 6 inches of rain. It’s so called because moisture builds up in the tropical Pacific Ocean around Hawaii and can move across the ocean, causing heavy rain and snow to hit the west coasts of the United States and Canada. The current storm is packing in more moisture, overwhelming already saturated areas.
Gov. Gavin Newsom’s office said the state has a record number of emergency assets in place to respond to “severe storms with dangerous and potentially life-threatening impacts.” . Those impacts included about 600,000 homes and businesses without power on Monday.

Landslide hits Hollywood Hills
Weather conditions improved in the Hollywood Hills on Monday, with warnings of “extremely dangerous conditions developing” including life-threatening landslides and flash flooding. A landslide caused a gas leak, forcing several families to evacuate. In the Studio City neighborhood, landslides caused severe damage to several homes and forced evacuations. In the suburb of Tarzana, three homes were submerged in a debris flow, and firefighters helped residents evacuate.
Flooding and small landslides were also reported in Santa Monica, West Hollywood, Malibu, and Beverly Hills.
“Life-threatening flash flooding is ongoing and will continue into Monday morning,” the Bureau of Meteorology said.
Los Angeles County Supervisor Lindsey Horvath urged residents near wildfire burn sites in Topanga and Soledad Valleys to evacuate ahead of possible landslides. The county set up shelters for evacuees.
“If you have not already done so, please gather your family, pets, and medications and leave immediately,” Horvath said at a briefing Sunday.
