A cold weather system is expected to impact the area from tonight through Thursday night. Increasing instability today and tonight will bring a slight chance of thunderstorms, capable of producing brief heavy downpours and small hail. Rainfall totals are expected to range between 0.10 and 0.75 inches from Ventura County northward, and between 0.01 and 0.25 inch for Los Angeles County. Locally higher totals are possible near heavier showers or thunderstorms. Snow levels are expected to fall to between 5000 and 6000 feet with some light snow accumulations likely at higher elevations. Snow levels should lower further to 4000 to 4500 feet Thursday morning with some snow possible on Interstate 5 over the Grapevine, which could lead to travel delays. Along with the rain and snow, there will be gusty southeast winds associated with the storm for tonight through Wednesday morning, especially on the Central Coast and over higher terrain.
A large westerly swell will continue through Thursday. This westerly swell will generate high surf conditions along west-facing beaches across the Central Coast as well as the coastal areas of Ventura and Los Angeles counties. Along the Santa Barbara County South Coast, high surf conditions are not expected, but surf heights will be at elevated levels. Along with the dangerous surf conditions, significant rip current activity will be likely across the near shore waters.
