    tonight over the North Bay Counties of Sonoma, Napa, and Marin,
    as well as the Santa Cruz Mountains. Rainfall amounts in excess
    of 5 inches have already fallen across portions of the North Bay
    since Thursday evening and an additional 1 to 2 inches of rain
    is likely on Friday night. In the Santa Cruz Mountains, rain
    totals thus far are up to about 2 inches in the wettest
    locations and an additional 1 to 2 inches are expected
    overnight.
    * Impacts...Roadway and small stream flooding is possible as well
    as urban flooding in poorly drained areas. Mud and rock slides
    are also possible in areas of steep terrain. Moderate rises will
    likely occur on mainstem rivers, but mainstem rivers are
    forecast to remain well within their banks. During periods of
    heavy rain ponding of water on roadways is likely. Very heavy
    rainfall rates over recent burn scars could potentially trigger
    flash flooding or mudslide/debris flows across and downstream
    from the burn scars.
