The foggy conditions are back Friday morning, which means another dense fog advisory has been issued through 9:00 a.m. This advisory stretches from northern San Luis Obispo County's coastal and inland valleys down to northern Santa Barbara County in the Santa Ynez Valley. Drivers can expect visibilty to be a quarter mile or less out on the highways, so it's important to increase following distance and be sure headlights are on.
Back at the coast, a high surf advisory for both counties remains in place. Beaches in SLO County could experience breaking waves from 10-16 feet through the start of next week. In Santa Barbara County, the waves won't reach the same heights, but there is still potential for coastal flooding through Sunday.
Daytime highs are still mostly in the mid to upper 60s Friday, with the exception of the south coast region and Santa Ynez Valley, two areas that could still reach the mid-70s Friday. Northwesterly winds will be moderate once again, staying close to 15-25 miles per hour through Friday evening.
A weak frontal system moving over San Luis Obispo and northern Santa Barbara Counties Friday night could bring a chance of showers to the interior valleys, mountains and foothills through Saturday.
