California drenched in unprecedented rainfall, killing three

At least three people died after trees fell on them during a strong storm in California. The storm caused flooding, mudslides, and power outages.

Firefighters have helped with more than 130 flooding problems and saved many people since the heavy rain started.

Experts predict that there will be a lot of rain and dangerous flooding until Tuesday.

The governor said there is a big problem with too much rain in eight counties, so he made a rule that there is a big emergency.

The storm is caused by something called an “atmospheric river. ” This happens when water evaporates into the air and is carried by the wind, creating long streams of water in the sky, kind of like rivers on land.

This slow storm is the second big rainstorm to hit California in two weeks.

Authorities have told people to leave their homes in some neighborhoods in the southern part of the state, including in Los Angeles. The city leaders said it’s an emergency.

LA Mayor Karen Bass said on Monday that it is really important to stay safe and not drive on the roads right now. “Only go out of your house if you really have to. ”

Up in northern San Francisco, which is one of the hilliest cities in the world, landslides have been happening in the area.

Three men have been killed by trees falling on them. One of the accidents happened in Sacramento Valley, and another one occurred when a tree fell on a house in Santa Cruz County. A man who was getting old died in Yuba City, in Northern California, when a big redwood tree fell in his backyard.

The storm also brought a lot of snow to the area. An avalanche happened on Monday at a ski resort in Lee Canyon near Las Vegas, Nevada. Luckily, no one got hurt.

Mud and rocks are sliding down the mountains in Los Angeles. On Sunday, 16 people had to leave their homes in Hollywood Hills because mudslides damaged their houses and caused gas leaks.

People saw fridges and pianos floating on the streets along with all the other mess.

Problems also happened in the fancy neighborhoods of Bel Air and Beverly Hills in LA.

People driving in Los Angeles and San Bernardino County got stuck because of flooding. Rescuers had to help them.

A dad, mom, and daughter had to leave their car on Monday because of a flood. They climbed a tree to stay safe from the water. The San Bernardino fire crews saw them do this.

Rescuers helped 19 people on a boat after it got stuck on rocks near Long Beach. The boat lost its tall pole and the wind was very strong.

Lifeguards sent swimmers to help the group, who were then taken to safety in boats. Only one person was hurt, but not seriously.

Very strong winds, reaching up to 70mph (112km/h), have cut off electricity and knocked down trees. But the winds are expected to calm down a lot by Monday night.

It is happening after a very successful day for the state. The National Weather Service (NWS) said that on Sunday, 4. 1 inches (104 centimeters) of rain fell in downtown Los Angeles, breaking the old record of 2. 5 inches set in 1927.

By Monday afternoon, some areas in LA County had gotten more than 11 inches of rain since the weekend – almost reaching the nearly 15 inches that the region usually gets in a whole year.

The storm got really strong really fast because cold air and warm sea air mixed together. This made the air pressure drop quickly and created a “bomb cyclone,” according to UCLA climate scientist Daniel Swain.

Winds going over 100 miles per hour were reported in the Bay Area, he mentioned in a talk on Monday.

The storm and flooding made schools close from Malibu to Sonoma County, near San Francisco.
