ABC7 meteorologist Brianna Ruffalo details rainfall totals after Hilary soaked Southern California
LOS ANGELES (KABC) -- Once a Category 4 hurricane, Hilary tore through Southern California with historic rainfall on Sunday, flooding roads and knocking out power.
Rainfall totals from Hilary have reached 13.5 inches in San Bernardino County, and 11.7 inches in the mountains of Riverside County.
Los Angeles County recorded over 7 inches of rain. Downtown L.A. recorded 2.48 inches of rainfall on Sunday, making it the wettest August day ever in that area, according to the National Weather Service.
Palm Springs saw more than 3 inches, which broke the desert city's all-time daily summer rain record.
San Diego saw 1.82 inches of rain, making Sunday the wettest August day on record in the city, according to ABC News. Plus, Escondido and Cuyamaca saw 2.66 inches and 4.11 inches, respectively, marking the wettest month of August for those regions.
Large swaths of Southern California that bore the brunt of Tropical Storm Hilary include Palm Springs and the rest of the Coachella Valley, where several roads and neighborhoods were inundated with flash flooding and mud flows.
