Bay Area Wakes Up to Thick Fog Blanketing Region

Visibility for many locations was reduced to a quarter-mile or less

Many Bay Area residents woke up Tuesday to thick fog blanketing their neighborhoods.

The National Weather Service issued a dense fog advisory for much of the Bay Area as a result of conditions, but that advisory expired at 10 a.m.

Visibility for many locations, including the region's three major airports, was reduced to a quarter-mile or less, the weather service reported around 5 a.m.

The reduced visibility made for difficult and tricky driving conditions. Motorists were advised to slow down and use their low-beam lights.
