Brrrrrrace Yourself for a Chilly Day

Frost made Monday morning that much tougher



    Jeff's Forecast: Fog To Drop Temps

    It seems like just days ago we needed the air conditioner to make it through the late afternoon heat and now the people of the Bay Area are talking about throwing the switch in the other direction and turning on the heat.

    This is October, so we shouldn't be surprised.

    Sunday morning was cold, but Monday was even colder. Meteorologist Rob Mayeda said Monday was expected be the coldest day so far this fall. It's below average for this time of the season but the temperature will come up a bit and be more like normal on Tuesday.

    The forecast is so cold, the National Weather Service issued a frost advisory from 4 a.m. to 9 a.m. Monday. The advisory was short-lived, however. It was canceled at about 6 a.m.

    Clear skies, calm winds and cool temperatures are expected to lead to patchy frost, and temperatures may drop between 32 and 35 degrees.

    The frost advisory is effective in San Francisco, Santa Cruz, San Mateo, Marin, Monterey, Contra Costa, Napa, Sonoma, Santa Clara and Alameda counties.

    The frost advisory comes a day after wind made itself known up and down the Peninsula. Hundreds of people in San Mateo County lost power Saturday night after heavy winds knocked down power lines. Most customers were back up and running by daybreak Sunday.

    Wind gusts up to 55 mph were reported Saturday along the Pacific Ocean and near the San Francisco International Airport, according to the National Weather Service.

    Winds toppled a home in San Francisco under renovation.

    At 8:30 p.m. a multi-story house on Arleta Avenue lost its top floor. Video from the scene showed it fell over crushing floors below.

    No one was at the home at the time.

    A fireman at the scene said he thinks the wind somehow got caught in the roof of the home and lifted it up before it crashed back down.
