A freezing fog advisory is in effect until 9 a.m. Saturday. This is when fog forms as super-cooled droplets and adheres to frozen surfaces. This can quickly produce a thin coat of ice on bridges and overpasses that is difficult to see.

Flying south through smoky skies down the famous Malibu coast, at first the burnt-out mansions are the exception -- solitary wrecks, smoldering away between rows of intact, gleaming beachfront villas.Where row upon row of family homes once stood, all that remain are occasional chimneys, blackened tree stumps and charred timber.

In addition to freezing fog, there is a high likelihood of black ice on roads overnight into Saturday morning, according to the National Weather Service.
