Los Angeles faces flooding threat as heavy rain slams region, tornado confirmed

A powerful storm system brought torrential rainfall to Los Angeles early Thursday, raising concerns over flooding risk, debris flow, and landslide dangers in areas recently devastated by wildfires. The National Weather Service confirmed that a weak EF-0 tornado touched down in Pico Rivera, causing damage to trees, poles, and structures across a four-block radius. Meanwhile, evacuation orders were issued for burn scar areas in Los Angeles County, as officials warned of the heightened threat of flash flooding.

More than 20 million people across Southern California remain under a flood watch, with heavy rain continuing through Thursday afternoon. The storm is part of an atmospheric river event, a weather phenomenon known for delivering intense precipitation across the West Coast.

Flooding and Mudslides Threaten Burn Scar Areas

The biggest concerns stem from burn scar areas, where vegetation loss from wildfires has left hillsides vulnerable to mudslides and rockfalls. Officials warn that these conditions can trigger dangerous debris flow, which could cut off roads and damage homes in affected areas.

The San Diego region, which is also in the storm’s path, is forecast to receive 1 to 3 inches of rain, with higher elevations expected to see even more. The Los Angeles County Sheriff’s Department confirmed that evacuation orders were issued for select neighborhoods impacted by the Eaton Fire and Palisades Fire, which scorched the region earlier this year.

The Los Angeles Mayor’s Office stated that emergency alerts were sent to residents in at-risk areas, urging them to prepare for possible evacuations. The National Weather Service also warned that further thunderstorms could develop, intensifying the flooding risk.

Tornado Confirmed in Los Angeles County

In addition to the flooding concerns, the National Weather Service confirmed that an EF-0 tornado struck Pico Rivera overnight. The tornado, which brought winds of up to 85 mph, downed power lines and uprooted trees, leaving behind significant damage in a concentrated area.

While tornadoes are uncommon in Southern California, they have occurred in the past during intense storm systems. Local emergency crews were dispatched to assess the damage, and power restoration efforts are underway in affected neighborhoods.

Storm to Move South, Impacting San Diego

The storm system is expected to push further south by Thursday afternoon, bringing heavy rainfall to San Diego before tapering off later in the day. Forecasters say another storm system could arrive next week, prolonging the wet conditions across California.

As Southern California braces for continued weather hazards, officials urge residents in flood-prone areas to remain vigilant, avoid unnecessary travel, and stay updated on emergency alerts.
