The fog is thick and dense across the Central Coast Monday morning. A dense fog advisory has been issued for the beaches and coastal valleys of San Luis Obispo County and northern Santa Barbara County through 9 a.m. During this time, visibility could drop to one-quarter mile or less out on local highways, so it is advised that drivers use their low beams, increase following distance and decrease speed when driving through the dense fog.

While the sky conditions will be mostly clear for valley locations, there could be lingering stratus along the coast Monday afternoon, similar to Sunday's conditions. Daytime highs will be right around normal for this last day of Summer before the Fall Equinox Tuesday. Inland valley locations will range from the mid-80s to low 90s and coastal valley regions will have a mix of 70s and low 80s. For the beaches, marine influence could definitely keep conditions on the cooler side with max daytime highs from the low to upper 60s. These temperatures will remain fairly consistent through Tuesday before a ridge develops Wednesday, which will likely decrease stratus. At the same time, the offshore flow could bring temperatures up across the Central Coast by about five to ten degrees.

Wind speeds are going to be fairly mild as well as coastal northwesterly winds will struggle to get past 10-15 miles per hour. Further inland and over the interiors, winds will also cap at similar speeds but will otherwise be shifting out of the northwest.
