A dense fog advisory is in place for coastal regions across San Luis Obispo and Santa Barbara Counties Tuesday morning. The advisory will remain in effect through 9 a.m. as visibility on local roads could decrease to a quarter-mile or less throughout the morning commute. The marine layer will clear towards valley locations, but similar to Monday, foggy skies could persist at the coast. Tuesday could be a partly cloudy day due to the remnants of Hurricane Marine, which is some 1,500 miles west of the southern tip of Baja California.

Increased onshore flow and deepening marine layer will bring daytime highs down by some five degrees Tuesday. The inland valleys will hang on to the 90s, but most coastal valley regions will stay between the mid-70s and mid-80s. Towards the coast, especially with the marine influence, daytime highs will cool down to the 60s.

Northwesterly winds will be mild Tuesday, staying around or below 10 miles per hour. A few exceptions to this will include the Gaviota coastline where wind speeds could reach 16 miles per hour by Tuesday evening.

The big talker in the forecast remains the chance for rain Friday and Saturday. These chances are really dependent on a low-pressure system that is moving in from Alaska. This system could bring a chance of rain showers Friday for areas north of Point Conception and more drizzle-like conditions to areas south of Point Conception. These conditions are expected to persist through Saturday, although, it's not determined just how much precipitation the Central Coast could receive.
