California Coast Under Weather Alert: Dangerous Seas Loom

Nearly the entire California coastline is under weather alerts issued by the National Weather Service, cautioning mariners and beachgoers about hazardous ocean conditions. These warnings come as an atmospheric river departs the region, with another storm set to arrive from the northwest. This incoming system is predicted to deliver substantial rain and mountain snow across California from Wednesday night through the end of the week.

Currently, alerts highlight dangerous seas and strong winds for vessels, with most advisories set to expire by Tuesday or Wednesday. However, officials anticipate similar alerts may be reissued as the next storm system approaches. Specific warnings include gale warnings with north winds up to 40 mph and seas of 11 to 14 feet in Northern California, alongside small craft advisories indicating lesser but still hazardous conditions.
