Thick Fog Blankets Bay Area Neighborhoods

Some Bay Area residents woke up to thick fog hanging over their neighborhoods Thursday morning.

The National Weather Service issued a dense fog advisory until 10 a.m. for areas hugging the San Francisco Bay and the Santa Clara Valley.

Visibility in some locations was reduced to one-quarter mile or less, according to the weather service.

Motorists were advised to slow down, turn on their low-beam lights and leave extra space between them and vehicles in front of them.

Just over one week ago, many Bay Area residents saw a similar scene as heavy fog blanketed the region during the morning.
