Rain is expected in Southern California Wednesday through Thursday as the National Weather Service warned of potential risks at beaches and thunderstorms from Oxnard to the Mexican border.
The Los Angeles-Oxnard Weather Service office estimates there is a 30 to 40 percent chance of thunderstorms, with concerns of minor flooding and widespread debris flows in Los Angeles and Ventura counties.
However, most areas will likely experience only minor impacts from these weather conditions, the bureau said.
The area most at risk of flooding is the Santa Monica Mountains, according to a weather service spokesperson.
“Some of the most vulnerable areas include first-year burn scars,” a spokesperson said.
The Palisades and Altadena areas are among those recently hit by wildfires.
As for rain amounts, the Los Angeles Weather Service expects 1.73 inches of rain in Thousand Oaks Wednesday through Thursday, with Oxnard at 1.53 inches, Santa Clarita at 1.47 inches, LAX at 1.31 inches, Covina at 1.29 inches and Long Beach at just under an inch.
