More rain fell Monday on parts of Southern California after causing mudflows over the weekend, helping firefighters but boosting the risk of toxic ash runoff in areas scorched by Los Angeles-area wildfires.

LOS ANGELES (AP) — More rain fell Monday on parts of Southern California after causing mudflows over the weekend, helping firefighters but boosting the risk of toxic ash runoff in areas scorched by Los Angeles-area wildfires.

Residents and first responders were on high alert for possible land movement in recent burn scar areas as a winter storm moves in.

Thunderstorms and heavier showers are most likely to occur through Monday afternoon, raising the risk of debris flows and mudslides in burn areas.

The rain, which may start on Saturday afternoon or evening, can help alleviate the dry conditions plaguing the region, but the incoming storm system could create other headaches, with slick, burned hills that can’t absorb water after being stripped of vegetation. That could lead to sudden debris flows, mudslides and flooding.

There is a 10% to 20% chance of flash flooding and landslides in some recently burned areas of Los Angeles County, forecasters say, including the Palisades and Eaton fire areas.

The Palisades and Eaton wildfires also continue burning in the Los Angeles area, leaving parts of Southern California with devastating fire damage.

Fast forward to now, the aftermath of a catastrophic January day in 2025, when extreme wind fueled the hellish Eaton fire that destroyed thousands of homes, killed at least 17 people, and leveled scores of local landmarks, schools, churches and businesses.

Officials cautioned that ash in recent burn zones was a toxic mix of incinerated cars, electronics, batteries, building materials, paints, furniture and other household items.

Rain has continued to fall across parts of Southern California, increasing the risk of toxic ash runoff in areas hit by flames.
