Rain in Southern California Triggers Flood Advisory, Concerns Of Mud Flows In Foothills

The first of two rainstorms to hit Southern California this week arrived before sunrise Monday, dropping more than an inch of rain in Ventura County and triggering concerns of mud flows in the city of Duarte. The storm is expected to let up this afternoon, said National Weather Service meteorologist Dave Bruno, but a second spell is expected overnight into early Tuesday. Even though the rainfall hasn’t been heavy compared with a series of atmospheric rivers that slammed California in January, it has sparked some concerns about overwhelming burn-scarred hillsides in the San Gabriel Valley.
