Due to the cliched fog blanketing the Bay Area this morning, the National Weather Service issued a fog advisory. It will be in effect until 11 a.m. What does that mean for you? Well, it means that drivers on Bay Area bridges and roads should proceed with caution, because visibility it something awful.

"Drivers on the Benicia Bridge can only see 75 feet in front of them," according to reports. "Visibility is roughly a quarter mile in other parts of the region, according to the National Weather Service."
