Los Angeles, Orange and San Diego counties were expected to see little rain — perhaps a quarter of an inch in the cities of L.A. County, half an inch in the San Gabriel Mountains, and anywhere from a few tenths of an inch to three-quarters of an inch in the valleys of the Inland Empire and San Diego County. The rain for those areas could begin Monday night and continue into Tuesday.
