    Marine Weather Statement - 9:18am Sat Oct 31 2026

    ...ISOLATED WATERSPOUTS POSSIBLE TODAY ACROSS THE COASTAL WATERS...

    Scattered showers will continue across the coastal waters through
    Sunday morning. With increasing instability and enhanced potential
    for rotating storms, isolated waterspouts will be possible today,
    mainly from the coastal waters off of the Santa Barbara Central
    Coast southward to the inner waters south of Point Conception.
    These same areas will also have a 5-10 percent chance of
    thunderstorms today.

    Waterspouts are dangerous and can capsize boats. Never move
    closer to investigate or take photos. The best way to avoid a
    waterspout is to move at a 90 degree angle to its apparent
    movement.
