Los Angeles flooding storm has soaked Southern California, causing widespread flash floods and prompting urgent evacuation warnings. Torrential rain hit the region on Wednesday, with some areas receiving more than an inch of rain per hour. Officials warned residents to avoid roads and for those near wildfire-scarred foothills to evacuate immediately.
The heavy rainfall came from an atmospheric river, a massive current of moist air flowing from the Pacific Ocean. This storm swept inland over the greater Los Angeles area, drenching communities during what is normally a busy holiday travel period.
The U.S. National Weather Service described the storm conditions as “life-threatening,” with flash flooding ongoing across much of Los Angeles County. Authorities issued a flash-flood warning through 6 p.m. PST, urging motorists not to drive unless they were escaping dangerous areas or following evacuation orders.
City officials also called for evacuations in Pacific Palisades, where last year’s wildfires left some homes highly vulnerable to mudslides and debris flows. Around 130 properties in the region were considered at high risk due to the combination of heavy rain and fire-damaged terrain.
In addition to rainfall, strong gusty winds accompanied the storm, increasing the risk of fallen trees and downed power lines. Forecasters said upper elevations in the Sierra Nevada could see heavy snow as the storm continues.
Meteorologist Ariel Cohen of the National Weather Service reported that some foothill areas had already received 4 to 8 inches of rain by 9 a.m. PST. Los Angeles City News Service confirmed multiple rockslides in the mountains. Projections suggest that some lower-elevation mountain areas could see more than a foot of rainfall by the end of the week.
The storm also triggered a rare tornado warning for a small portion of east-central Los Angeles County, near Alhambra, due to intense thunderstorm activity. Officials emphasized that residents must remain alert and prepared for sudden changes in conditions.
Authorities warned that driving is extremely dangerous due to flooded roads, debris, and slick surfaces. Emergency services urged people to follow evacuation instructions and avoid unnecessary travel.
This atmospheric river storm is expected to persist through Friday, creating continued hazards across Southern California. Residents were advised to monitor local news and official alerts for updates on flash floods, mudslides, and severe weather threats.
The heavy rains on Christmas Eve highlight the increasing risk posed by atmospheric rivers to wildfire-affected areas. Fire-scarred slopes are especially prone to rapid debris flows, making timely evacuation and careful monitoring crucial for public safety.
As Southern California faces its second day of extreme weather, authorities continue emergency response operations, including road closures, evacuation assistance, and damage assessment. The combination of heavy rainfall, gusty winds, and potential snow in the mountains makes this one of the region’s most serious storms this holiday season.
