Los Angeles has wettest day in nearly 20 years after more than a month's worth of rain
From CNN Meteorologist Mary Gilbert
More than a month's worth of rain fell in downtown Los Angeles in just 24 hours Sunday in what was the wettest day there in nearly 20 years.
The city’s downtown weather reporting station located near the University of Southern California recorded an astonishing 4.10 inches of rain Sunday. Downtown Los Angeles averages 3.64 inches of rain in February, typically its wettest month of the year. It was the wettest day in the city since 5.55 inches fell nearly 20 years ago on December 28, 2004.
Sunday's deluge smashed the rainfall record for the date and made it one of the ten rainiest days ever downtown.
Add Sunday's record rainfall to what fell in the city from last week's atmospheric river and downtown Los Angeles has picked up 5.64 inches from both storms. This marks about 40% of what the city sees in an entire year and rain is still falling.
The city’s other reporting site at Los Angeles International Airport also picked up record rainfall Sunday. Rain at the airport totaled 1.76 inches – more than triple the date’s previous record of 0.56 inches set in 1958.
Northern California man killed by fallen redwood tree as atmospheric river produces strong wind gusts
From CNN’s Andy Rose
A man in northern California was killed Sunday by a large redwood tree that fell as powerful wind gusts moved through the area.
“Through the investigation, it appeared he was possibly using a ladder to try and clear the tree away from his residence when it fell on him,” the Yuba City Police Department said in a statement.
Authorities have not blamed the incident on the weather, but winds in Yuba City were gusting to nearly 50 miles per hour at around 5 p.m. local time, when police say neighbors heard the tree fall. Fallen power lines have resulted in power outages to nearly 12,000 customers in Sutter County, according to Pacific Gas & Electric.
The identity of the victim has not been released.
“This was an unfortunate accident and our condolences are with the male’s family and friends,” police said.
Yuba City is about 40 miles north of Sacramento.

An atmospheric river has brought potentially dangerous weather to Southern California. Here's what to know
From CNN Staff
A potent atmospheric river has brought extreme rainfall and strong winds to Southern California on Sunday, with the weather set to continue into the day Monday.
Authorities are urging people not to travel, and some people have been evacuated from their homes due to the risk of landslides.

- Rare high flood risk:A firehose of rain is expected to stall over Southern California, including Los Angeles, worsening the high risk of flooding throughout Monday.
- High power outages:Strong winds and rain have knocked out power for nearly 700,000 customers in California, particularly along the coast, according to the tracking websitePowerOutage.us.
- Rare rain risk:The Weather Prediction Center issued a rare high risk of excessive rainfall — or a Level 4 of 4 — for more than 14 million people across Southern California on Monday. This includes downtown Los Angeles, Anaheim and Long Beach.
- Landslides:The weather service warned of “numerous damaging landslides” in the cities of Malibu and Beverly Hills in Los Angeles County, along with the Santa Monica Mountains and adjacent foothills.
- Evacuation orders:Some residents inSanta Barbara,San José,Los AngelesandVentura Countywere under evacuation orders issued over the weekend as officials warned of potential “life-threatening” floods and landslides.

More than 14 million people in Southern California face rare high risk of excessive rainfall
From CNN's Robert Shackelford
Over 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.

Here's what meteorologists mean when they say "atmospheric river"
From CNN Meteorologist Mary Gilbert
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.
