Eureka, CA – High tides combined with storm-driven surf could push seawater into low-lying coastal areas of Northern California on Saturday morning, raising the risk of flooding along beaches, harbors, and vulnerable roadways from Del Norte County south through Mendocino County.
According to the National Weather Service office in Eureka, a Coastal Flood Warning is in effect from 9 a.m. to 1 p.m. Saturday as enhanced southerly winds and large surf elevate water levels above typical astronomical tides. Officials say tides may exceed levels observed Friday, increasing the chance of saltwater covering parking lots, coastal trails, and shoreline access roads.
In Humboldt Bay, high tide late Saturday morning could impact low spots near marinas, boat ramps, and shoreline neighborhoods, including areas around North Spit and King Salmon. Crescent City may also see water pushing into low-lying harbor areas, while Arena Cove and other exposed Mendocino County locations face minor inundation during peak tides.
Drivers are urged to avoid flooded roads, especially near the coast, and never attempt to cross water-covered pavement. Beachgoers should stay well back from the surf zone, as large waves can overtop jetties and sea walls with little warning.
The flooding risk may return Sunday and possibly Monday as elevated tides continue. Additional advisories could be issued if conditions worsen, especially with ongoing wind and surf impacts along the North Coast.
