A large west to northwesterly swell will continue to produce breaking waves at the Morro Bay and Ventura Harbor entrances through at least this afternoon. These conditions have a history of capsizing vessels of various sizes resulting in serious injury or death, even to the most experienced mariners. Mariners are urged to stay clear of these harbor entrances. For more information, contact the local harbor patrol or coast guard station and continue to monitor NOAA Weather Radio for the latest weather information.
