National Weather Service forecasters today warned of a strong storm system is making its way toward Los Angeles, saying that the storm could trigger flooding and debris flows, particularly in recent burn areas.

The first wave of the strongest storm of the winter began hitting Southern California on Wednesday, but the most damaging rains are expected Thursday.

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.
