Los Angeles Heavy Rain may Trigger Mudslides, 180,000 People Evacuated

LOS ANGELES, Nov. 16, 2025 – On Saturday, November 15, most of the time, the Los Angeles and Southern California metropolitan area experienced continuous heavy rain, bringing ongoing moderate to high risks to communities previously affected by wildfires, including sudden floods, debris flows, and strong winds. Up to 180,000 people in the region have been evacuated.

According to the forecast from the National Weather Service, parts of the Los Angeles area are expected to receive rainfall reaching up to one inch per hour (about 2.5 centimeters) on Saturday, with the storm expected to weaken by Saturday evening.

Rainfall in downtown Los Angeles over the weekend could reach 2 to 4 inches (5 to 10 centimeters), while other areas may see rainfall totals as high as 8 to 10 inches (20 to 25 centimeters).

However, another rotating low-pressure system is moving toward the Los Angeles area, expected to bring thunderstorms and weak tornadoes starting from next Monday (17th), with more rainfall expected next week.

Meteorologist Joe Sirard from the National Weather Service stated that if the rainfall continues as forecasted until next Tuesday (18th), it could be the wettest November in the Los Angeles area since 1985.

Large areas of the Los Angeles area, Santa Barbara County, and Ventura County remain under flood warnings, expected to be lifted by Saturday evening.

Due to the possibility of the storm increasing the risk of debris flows in the burn scar areas of Eaton and Palisades fires, locals are on high alert. Evacuation warnings for many communities affected by the deadly January fire in Los Angeles have been in place until Sunday morning at 8 a.m.

Los Angeles Mayor Karen Bass posted on social media that the city government has issued mandatory evacuation orders for “some vulnerable homes” near the fires.

Mayor Bass’ office stated that rescue personnel and at least one helicopter are on standby to respond to possible severe flooding or debris flows on unstable terrain.

The Los Angeles County Department of Public Works predicts that over a dozen communities that have experienced fires in the past year, including parts of Malibu and Hollywood Hills, have a moderate risk of debris flows.

The heavy rain may result in debris being washed onto roads, causing some streets to be completely blocked. The department noted that some buildings could also be threatened based on local terrain.

In addition to debris flows, the National Weather Service warns that the Los Angeles area may also experience severe flash floods, with possible power outages and road closures.

As of Saturday morning, downtown Los Angeles has recorded 1.32 inches of rainfall, surpassing the November average of 0.78 inches.
