Some areas in Los Angeles County saw record single-day rainfall on Tuesday, March 15, with the fast-moving storm system also leading to a swift-water rescue in Jurupa Valley and road closures in Orange County because of flooding and mudslides.
Downtown Los Angeles, Los Angeles International Airport and the Long Beach Airport all saw new rainfall records for March 14, according to the National Weather Service. LAX had the biggest jump, receiving 1.97 inches of rain yesterday, storming past the old record of 0.43 inches for the same date in 1982.

Tuesday’s heavy rainfall led to the closure of a portion of Pacific Coast Highway in Huntington Beach and another closure along Camino Capistrano in Dana Point due, officials said.
Those heading into Laguna Beach were also warned by the city of delays because of flooding along Laguna Canyon Road.
Orange County was added to Governor Gavin Newsom’s state of emergency list, which also includes San Bernardino and Los Angeles counties. A flood watch remained through Wednesday afternoon for the three counties.
Two portions of Highway 18 in the San Bernardino Mountains remained closed after rockslides and snowfall, Caltrans said.
