A cold early season storm system will move across Southwest California Tuesday through Thursday. It’ll bring light rain and mountain snow to the area, as well as strong winds. Snow levels will likely fall to between 5,500 and 6,000 feet by Wednesday afternoon, with light snow accumulation possible above 6,000 feet. With this potentially being the first measurable rainfall most of the area has received since the spring season, hazardous driving conditions are likely. Accumulated oil on pavement surfaces could make the roads slippery. Morning and afternoon commutes may be slower than usual due to more accidents.
