SEA/SWELL:

    Today's 6- to 8-foot northwesterly (290-degree, deep-
    water) sea and swell (with a 5- to 13-second period)
    will  remain at this level through tonight, decreasing
    to 4 to 6 feet (with a 7- to 15-second period) on
    Friday into Saturday. 

    A 3- to 5-foot northwesterly (290-degree, deep-
    water) swell (with a 8- to 16-second period) is
    forecast along our coastline on Sunday into Monday.

    A 4- to 6-foot northwesterly (290-degree, deep-
    water) sea and swell (with a 7- to 14-second period)
    is forecast along our coastline on Tuesday into next
    Thursday.  

  ATMOSPHERIC CONDITION:

    Short lived convective cells (cumulonimbus clouds)
    moved over the Templeton area yesterday afternoon
    and produced areas of hail.   

    A pattern of moderate to fresh (13 to 24 mph) Santa
    Lucia (northeasterly) winds developing during the
    night & morning hours, shifting out of the northwest
    and increasing the strong to gale-force (25 to 38 mph)
    levels during the afternoon hours will continue
    through Saturday.

    This condition will produce dry conditions under
    mostly clear to partly cloudy skies. However, areas
    of dense fog may develop in the inland valleys
    during the morning hours.

    The upper-level winds will continue to push a cold 
    air mass from the north into the Central Coast.
    Consequently, temperatures will drop to well below
    seasonal averages. Low temperatures in the North
    County and wind sheltered valleys will drop to the 
    mid to high 20s, while closer to the coast, low
    temperatures will lower to the mid 30s on Friday
    into Saturday. Afternoon highs will range between
    the mid 50s to low 60s.

    Over the last 18 hours the numerical model runs have 
    significantly reduce the strength of Sunday's weather 
    system. A 1,002 millibar surface low combined with an
    upper-level though will produce gentle to moderate 
    (8 to 18 mph) southerly winds, mostly cloudy skies and 
    rain. Snow levels will lower to the 2,500 and 3,000 
    foot range with light accumulations on the higher
    peaks of the Central Coast. 

    A few lingering rain showers are expected Monday,
    then dry and much warmer weather is forecast during
    the first week of March which may reward us with a
    spectacular bloom of wildflowers. We have reached the
    amount of rainfall needed to germinate many of the 
    annual flowers.
