A cold, potent storm system off the coast of Northern California
will continue moving slowly southward through the middle of the
week, bringing a slight chance of thunderstorms to the coastal
waters through Tuesday. Any thunderstorms that form will be
capable of producing chaotic locally gusty winds and rough seas,
dangerous lightning, heavy rainfall with reduced visibility, and
isolated waterspouts. If a waterspout is spotted, head away at a
90 degree angle from the apparent direction.

Consider remaining in safe harbor until the storm passes. Monitor
NOAA Weather Radio for the latest information, forecasts, and
warnings..
