The first of two small rainstorms moved into the Los Angeles area Monday afternoon. Light rain was reported in Santa Monica, Long Beach and other coastal cities. The first storm is targeting areas west of the mountains – from Los Angeles International Airport to Burbank – with a tenth to a quarter of an inch of rain, with most of it going to mountainous areas of the county such as the Antelope Valley. Thunder is possible, but no warnings of advisories have yet been issued, according to the National Weather Service. The second storm, more mild than the first, will hit the mountains between Thursday and Saturday.
