California Coast Under Weather Alert: Dangerous Seas Loom
19 Nov
Summary
- Weather alerts issued for nearly all of California's coastline.
- Dangerous ocean conditions with strong winds and high seas expected.
- Incoming storm to bring heavy rain and mountain snow later this week.

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.
Various National Weather Service offices, including Eureka, San Francisco, and Los Angeles, have issued alerts ranging from gale warnings to small craft advisories and marine weather statements. These advisories warn of gale-force winds, rough seas, lightning, heavy rain, reduced visibility, and potential waterspouts, urging mariners to avoid dangerous conditions or seek safe harbor.
