Forecasters released a breakdown Tuesday of where and when heavy rainfall this week is expected to hit areas of Southern California left burn-scarred by recent wildfires, raising the risk of potentially dangerous debris flows in those parts of the region.

“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.”

Precipitation was lighter than expected on Wednesday, with another storm on the way Thursday night into Friday.

According to The Weather Channel, the storm raises major concerns for flash flooding and debris flows, especially in areas recently scorched by wildfires, including the Eaton and Palisades fire zones in Southern California.

A storm starting overnight Tuesday in California is expected to bring a high risk of debris flows later this week to the burn areas from the Los Angeles County fires. Between 2 and 3 inches of rain is expected to fall in the Palisades Fire area and between 3.
