Over 14 million people in Southern California face rare high risk of excessive rainfall
From CNN's Robert ShackelfordOver 14 million people are under a high risk of excessive rainfall on Monday across Southern California, according to the Weather Prediction Center.
The WPC has issued a rare level 4 out of 4 warning to affected areas including Downtown Los Angeles, Anaheim and Long Beach.
Rainfall rates across this high-risk area could approach 1 inch per hour, which could lead to rainfall totals of 4 to 8 inches, and possibly reach 8 to 14 inches in mountain and foothill terrains.
The warning in context: Rare Level 4 “high risk” alerts are issued on fewer than 4% of days per year on average, but are responsible for more than 80% of all flood-related damage and 39% of all flood-related deaths.
This event is part of an atmospheric river: a moisture plume pumping off the Pacific Ocean, feeding off warmer-than-average waters.
"Numerous damaging landslides" could hit Malibu and Beverly Hills
From CNN's Robert ShackelfordThe National Weather Service has warned of “numerous damaging landslides” in the cities of Malibu and Beverly Hills as a powerful storm drenches California.

Numerous damaging landslides, flooded roadways, submerged vehicles, and flooded creeks and streams were ongoing in the warning area as of 11:38 p.m. PT, the NWS Los Angeles said.
Automated rain gauges indicate between 5 and 8 inches of rain has drenched those areas, and rainfall can still rise by 1 to 4 inches, the NWS Los Angeles estimated.
The potential impacts include life-threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses as well as destructive and life-threatening landslides.
Locations that will experience flash flooding includeWestlake Village, Malibu, Woodland Hills, Encino, Santa Monica, Agoura Hills, Van Nuys, Beverly Hills, North Hollywood, Hollywood, Universal City, Burbank, Griffith Park, Topanga State Park, Calabasas, Pacific Palisades, Malibu Creek State Park, Brentwood and Interstate 405 through the Sepulveda Pass.

From CNN’s Cindy Von Quednow![February 4 California storm updates | CNN (22) February 4 California storm updates | CNN (22)](https://i0.wp.com/media.cnn.com/api/v1/images/stellar/prod/32e26a83-fb0f-4817-8311-d66214dd3344.jpg?c=original&q=w_1280,c_fill)
Los Angeles Mayor Karen Bass speaks at a news conference on Sunday.
Los Angeles Mayor Karen Bass on Sunday said the city is “operating in an all hands on deck manner” to keep residents safe during the powerful rain storm that is drenching the Southland.
She vowed to keep Angelenos informed during the storm, but also urged residents to stay safe, take precautions and be prepared for any emergencies.

The atmospheric river will bring "one of the most dramatic weather days in recent memory" to LA
From CNN Meteorologists Caitlin Kaiser & Elisa RaffaThe atmospheric river that is already dumping heavy rain across parts of northern and central California is set to bring “one of the most dramatic weather days in recent memory” to Los Angeles, according to the National Weather Service.
The rainfall forecast in Southern California continues to increase as the system begins to move into the area.
Downtown Los Angeles is forecast to see over 6 inches of rain through Tuesday, while surrounding areas can see anywhere from 5-10 inches.
Putting this in context: The average annual rainfall for Los Angeles is 12.23 inches, meaning that nearly half a year’s worth of rain could fall in the next 48 hours. Combined with the 2.49 inches that fell in the city on February 1, Los Angeles could potentially receive almost a year’s worth of rain in the first week of February alone.
Other hazards: Landslides, flash flooding, falling trees, power outages and high waves are all concerns in areas experiencing high rainfall rates. Rising river levels will also contribute to flash flooding and pose a risk of drowning for anyone near the channel area. Some locations at higher altitudes will be impacted by heavy snow and “may be shut off for a day or two with heavy snow covering access roads,” adds the weather service.
Local officials in Los Angeles are urging people living in affected areas to stay off the roads through at least Monday morning and to heed any evacuation orders.

What is an atmospheric river?
From CNN Meteorologist Mary Gilbert![February 4 California storm updates | CNN (30) February 4 California storm updates | CNN (30)](https://i0.wp.com/media.cnn.com/api/v1/images/stellar/prod/9064b994-e60f-4db7-b5c3-30c4ff4b7ed5.jpg?c=original&q=w_1280,c_fill)
Visitors walk by giant sequoias as snow falls during an atmospheric river storm in Kings Canyon National Park in California on February 1.
Atmospheric rivers are wide-reaching plumes of moisture that act like a firehose, tapping into warm, moist air from the tropics that storms can then unload as drenching rainfall and heavy snow over land.
These types of storms are winter hallmarks across the West Coast. Not all are harmful. Weaker atmospheric rivers deliver much-needed rainfall and snow to the region during the wettest months of the year.
This rainfall and snow is vital to western water supplies. It fills up water reservoirs that are critical resources during dry, hot summers.
But atmospheric rivers can quickly become more hazardous than helpful. Excessive rainfall unleashed by these potent storms increases the chances for flooding, particularly when a series of storms happen in sequence with little time to dry out between.
Last week’s atmospheric river broke multiplerainfall records across California and triggered road closures and water rescues.
Atmospheric rivers aren’t exclusive to the West Coast. They can also impact the eastern US andhappen frequently inparts of Europe, Africa, Australia and New Zealand.
The weather in Southern California could be life-threatening, experts warn
From CNN's Elisa Raffa, Allison Chinchar and Sara TonksThe Weather Prediction Center is warning of a potentially life-threatening and dangerous flood event expected to unfold in parts of central and Southern California today.
The center has issued a rare Level 4 of 4 risk of excessive rainfall for Los Angeles, Santa Barbara and Oxnard, on Sunday. A more widespread Level 3 risk exists for much of coastal California, including San Francisco, where the National Weather Service has also issued its first-ever hurricane force wind warning for the region.
In central and Southern California, widespread rainfall totals of 3 to 6 inches are expected – more than a month’s worth of rain for most.Los Angeles averages just 2.99 inches of rain in February, their wettest month of the year on average.In the mountains and foothills of Southern California, the weather service is forecasting up to a foot of rain.
The National Weather Service in Los Angeles warns the multi-day rain event could be dangerous and life-threatening. It could cause extensive road flooding and significant debris flow over areas that have previously burned in wildfires, possibly causing mudslides in higher terrain. Creeks and streams will rise.
Putting this rare warning into context: It’s hard to emphasize how big of a deal and how rare a Level 4 “high risk” alert is. They are issued on fewer than 4% of days per year on average, but are responsible for more than 80% of all flood-related damage and 39% of all flood-related deaths.
This event is part of an atmospheric river: a moisture plume pumping off the Pacific Ocean, feeding off warmer than average waters.
Dr. Daniel Swain, a climate scientist known for work on Western extremes, notes that heavy rain events like the one unfolding are becoming 10% more intense thanks to more fuel from a warmer climate.
Officials issued evacuation orders for some areas of Ventura and Santa Barbara counties ahead of storm
From CNN’s Rebekah RiessThe Ventura County Sheriff’s Office issued several evacuation orders for certain communities Saturday morning, along with warnings and advisories to county residents.
The orders will be in place until 5 p.m. local time Sunday, according to areleasefrom the sheriff’s office.
The sheriff’s office also warned residents of potential landslides or debris flows, which may be caused by the amount of anticipated rain.
Residents in need of temporary shelter are encouraged to go an emergency evacuation shelter set up by the Ventura County Human Services Agency and American Red Cross.
In Santa Barbara County, an evacuation order is in place for properties along waterways and those in the area of Sycamore Creek, according to county Sheriff Bill Brown. Deputies will be going door to door to notify residents in the evacuation zones.
All county state beaches are also closed until further notice, Brown added.
Flooding is expected on streets in neighborhoods and along the highways, according to Brown, and some areas could see as much as 6 inches of floodwaters.
Several school districts in the region will also cancel classes Monday, including Santa Barbara Unified,Lompoc Unified and the Santa Maria-Bonita School District.
In addition,Santa Barbara City Collegeannounced it will have remote instruction on Monday.
