After days of rain, California is seeing the impacts of a massive atmospheric river system.

Rainfall records were broken in locations across Southern California on Saturday, topping previous records dating back to the historic floods of 1952. Downtown Los Angeles and airports in Long Beach, Burbank, Santa Barbara, and Paso Robles all topped their highest rainfall for the day.

The region had been bracing for the event, as areas that had been damaged by wildfires earlier this year are particularly susceptible to flash floods and mudslides.

Mandatory evacuation orders were issued for some residents living near the burn scars left behind from the Palisades and Eaton fires.

Workers were seen in some neighborhoods placing sandbags to help prevent runoff in Altadena.

As the storm battered the region on Friday night, a boat off the coast near Imperial Beach capsized. At least four died in the incident and four more were hospitalized.

Damage Across California

Further north, the atmospheric river has left a trail of damage on the way to Southern California.

In Santa Cruz County, a tree fell on a California Highway Patrol car, leaving the officer with minor injuries.

In Monterey County, a father died and his 5-year-old daughter is still missing after they were both swept out to sea.

In Sutter County, a senior citizen died after trying to cross a flooded bridge in his car.
