Los Angeles is bracing for a weekend of rain and thunderstorms, according to the National Weather Service. The wet weather is expected to commence late Saturday night and persist through Sunday afternoon, with a 15% to 25% chance of thunderstorms. These storms could bring brief periods of heavy rain, gusty winds, and small hail, and there is a slight possibility of waterspouts or weak tornadoes. The storm system is moving into the area following a shift in a ridge of high pressure. The system may linger into Monday, potentially bringing wet snow to high elevations, particularly in the northern Ventura County mountains. Gusty winds are also expected in the Mojave Desert region.
