Dense fog advisory issued for Bay Area

MONTEREY — The National Weather Service is advising Bay Area commuters to travel carefully and prepare for sudden visibility changes as dense fog lingers in the region.

On Monday night, the forecast office in Monterey issued a dense fog advisory for valleys in the North Bay and East Bay; the North Bay coast; the Bay Area shoreline; San Francisco; Santa Clara Valley; and the San Francisco and San Pablo bays.

The advisory runs from 7 p.m. Monday through 11 a.m. Tuesday in the North Bay and San Francisco, and from 11 p.m. Monday through 11 a.m. Tuesday elsewhere.

The weather service said visibility reductions as low as a quarter of a mile are possible.

Dense fog, along with darkness, appeared to play a role in a traffic fatality early Monday morning in Mountain View. An employee arriving for work at a Walmart in the 600 block of Showers Drive hit a woman in the parking lot. She died later at a hospital.
