In the San Gabriel Mountains, heavy 30 to 60 mph winds, and 3 to 7 inches of rainfall are expected, said Mike Wofford from the National Weather Service.
A flood advisory is in effect until 8 PM PDT this evening for Los Angeles County, including Catalina Island. Rain rates between 0.20 and 0.50 inches per hour have become common. This will result in ponding of water across low lying areas and areas with poor drainage. #LArain pic.twitter.com/qAHQ2DGafA
