Storm force winds will be likely for the coastal waters north of Point Conception Tuesday afternoon through Tuesday night. The strong winds will bring dangerous and very steep, choppy seas. The storm will also bring the threat of thunderstorms, some of which could be strong, with locally damaging winds. Conditions are also favorable for isolated waterspouts. Monitor NOAA Weather Radio for the latest information, forecasts, and warnings. This will likely be a dangerous storm and mariners should exercise extreme caution and are urged to remain in safe harbor for the duration of the storm. $$ Black
