 SEA/SWELL:

     A 7- to 9-foot northwesterly (300-degree, deep-water) sea
     and swell (with a 5- to 15-second period) is expected
     along our coastline today and will remain at a 7- to 9-foot
     level through Tuesday, but with a gradually shorter period.

     A 4- to 6-foot northwesterly (300-degree, deep-water) sea and
     swell (with a 5- to 11-second period) is forecast along our
     coastline Wednesday, increasing to 5 to 7 feet (with a 5-
     to 12-second period) Thursday into Friday, further increasing
     to 8 to 10 feet (with an 8- to 16-second period) this weekend.

     Arriving from the Southern Hemisphere:

     A 1- to 3-foot Southern Hemisphere (180-degree, deep-water)
     swell (with an 18- to 20-second period) will arrive along
     our coastline Friday into Saturday.

     Note: Starting today the Central Coast will see nearly 21
           straight days of negative low tides - a rare
           occurrence indeed.

  ATMOSPHERIC CONDITION:

    Don't put away your jackets and sweaters just yet. 
    The ridge of high pressure responsible for the warm weather
    over the past few days has shifted east in response to an
    approaching 1,007-millibar low-pressure system and 
    associated cold front.

    The cold front will move through the Central Coast today
    with strong to gale-force (25 to 38 mph) northwesterly
    winds, increasing clouds, scattered rain showers and cool
    air. In fact, today's high air temperatures will only reach
    the 50s.

    An unstable air mass later today will create the
    potential for thunderstorms, with some containing locally
    heavy rain, small hail and gusty winds. Rainfall amounts
    are expected to range between 0.10 and 0.25 of an inch. This
    system will be cold, and snow levels will fall to 4,000
    feet today. The Sierra Nevada could receive up to a foot 
    of snow in the higher elevations.

    Note: Overnight lows are expected to drop to the mid-30s
          in the North County, which could allow frost to
          develop early Tuesday morning.

    Strong to gale-force (25 to 38 mph) northwesterly winds,
    below seasonal temperatures and partly cloudy skies are
    forecast on Tuesday into Wednesday with another chance 
    of light rain showers on Thursday. This system may be 
    followed by strong to gale-force (25 to 38 mph)
    northwesterly winds later Thursday into Friday.

    The winds will shift out of the northeast (offshore)
    Saturday into Sunday and high temperatures will reach the 
    low to mid 80s throughout the Central Coast.
