It probably will not afffect scheduled cruises, other than to result in a greater number of cloudy, rainy and/or somewhat windy days during the cruise, making a less pleasant and picturesque cruise experience. I don't know to what extent cruises adjust their routes and schedules due to short-term weather forecasts; I suspect these "extra" storms coming into Califonia from the west would not significantly affect them. If one or two of the storms are particularly strong, the schedule or route might be adjusted somewhat; I don't know for sure. Most of the storms are not a danger, just an annoyance.
