The strongest storm in a year is set to pound Southern California this week, with forecasters warning of potential widespread roadway flooding and the chance of landslides throughout the region — especially in areas recently charred in the devastating Los Angeles County firestorms.

The upcoming storm is likely to pose a higher risk for mudslides, debris flows and flooding than the rainfall this past week.

“Recent research shows that debris flows almost always happen in Southern California after wildfires, and given that there are multiple wildfires and each of them is pretty large, really we’re in a situation where the next large rainfall event is almost certain to generate some sort of debris flow.”

It’s too early to pin down the forecast with certainty, but as of Monday, the most likely scenario is that rain ahead of the storm will arrive Tuesday night, with rainfall amoun

Forecasters are concerned the storm could bring mudslides in and near areas scorched by the Palisades and Eaton fires.

Flames burned through brush and vegetation, reducing the soil’s ability to absorb water — allowing water to possibly flow quickly, picking up debris and creating dangerous mudslides, debris flows and flash flooding.

Snow, wind and the heaviest rain event of the season is expected this week in portions of Southern California prompting a flood watch warning.

Forecasters said excessive rainfall could lead to flash flooding and debris flows in recent burn scars, including the Eaton and Palisades fires.
