    .Northeast to east winds had decreased in most areas late Saturday
    afternoon and are expected to remain mostly light through
    Saturday evening. However, easterly winds are forecast to
    increase in the hills of the North and East Bay late tonight.
    Winds in the hills tonight are not expected to be as strong as
    last night, but still strong enough to create critical fire
    weather conditions when combined with the warm and very dry
    airmass and dry fuels. Expect very poor overnight humidity
    recoveries in the North Bay Mountains and East Bay Hills tonight
    with relative humidity values remaining below 30 percent, and even
    below 20 percent on the higher ridges. Minimum relative humidity
    values on Sunday are forecast to be 10 to 20 percent and as low as
    the single digits in the hills. In addition, high temperatures on
    Sunday are forecast to be warmer than Saturday by about five
    degrees. Overnight relative humidity recoveries are expected to
    be better for North Bay Valleys and winds will mostly be light in
    the valleys.
    Warm and very dry conditions are forecast to continue into Monday,
    but winds will generally be light, even in the hills, from mid
    morning Sunday through Monday.
