#fog

Fog is a quintessential part of the Bay Area, a seemingly simple suspension of water in air that has shaped our culture and ecology since time immemorial. For us, it is the ghostly embodiment of cold weather and maybe our only chance at a white Christmas. At its core, it only needs two ingredients cool temperatures and humid air and it forms when moisture condenses to form a cloud close to the surface of the Earth.

Fog in the region will be locally dense this morning with the fog reducing visibility to a quarter mile or less in spots.
