    2- to 3-feet (with an 8- to 14-second period) by Tuesday
    morning.

    Increasing northwesterly winds will generate a 6- to 8-foot
    northwesterly (310-degree, deep-water) sea and swell
    (with a 5- to 15-second period) will on Tuesday afternoon
    through Wednesday, becoming a 5- to 7-foot northwesterly

    first week of December.

  ATMOSPHERIC CONDITIONS:

    A ridge of high pressure over the Great Basin will produce
    moderate to fresh (13 to 24 mph) Santa Lucia (northeasterly/
    offshore) winds and clear, dry, and warmer conditions today.

    High temperatures today will reach the low to mid-80s
    along the beaches and coastal valleys (San Luis Obispo)
    and mid-70s in the inland valleys (Paso Robles).

    Dense Tule fog will continue to develop across the San
    Joaquin Valley.

    The Santa Lucia winds will decrease this afternoon into
    Tuesday morning, followed by fresh to strong (19 to 31
    mph) northwesterly winds, partly cloudy skies, and cooler
    temperatures on Tuesday afternoon and night.

    A ridge of high pressure will build over California starting
    Wednesday and will produce night and morning Santa Lucia
    winds that will persist through the Thanksgiving holiday with
    clear skies and above-average temperatures. In fact, by this
    weekend, temperatures could reach the 80s again.

    The longer-range models no longer indicate southerly
    pre-frontal winds or rain at the end of November.
