California – Salt spray lifted off Humboldt Bay this morning as waves pushed inland and rain streaked across windshields. Water is already creeping into low spots, and conditions are expected to worsen as powerful tides and steady rain collide through Sunday.
According to the National Weather Service in Eureka, a Coastal Flood Warning remains in effect through mid-morning, followed by a Coastal Flood Watch through Sunday afternoon. High astronomical tides combined with storm surge could produce 1 to 2 feet of inundation in low-lying coastal areas, with isolated spots seeing up to 3 feet near Humboldt Bay. Several coastal roads may close, and shoreline erosion is expected.
In Eureka, showers intensify today with temperatures near the mid-50s. South winds strengthen, with gusts topping 35 mph and locally higher near headlands. Drivers along Highway 101 and low-lying roads near King Salmon Slough and Arcata Bottoms should expect ponding, reduced visibility, and brief closures. Avoid coastal parking areas during peak tides.
Rain continues into Sunday as another wave of Pacific moisture moves inland. Flood concerns expand beyond the coast as rivers and streams respond to steady rainfall. A Flood Watch remains in effect through Sunday evening, with the risk of rockslides and debris flows in steep terrain. Plan extra travel time and monitor road conditions closely.
Looking ahead to the first full workweek of 2026, rain lingers into Monday before tapering. Cooler nights arrive midweek, with lows dipping into the upper 30s. While snow stays confined to higher elevations, slick roads remain possible during early mornings.
More advisories may be issued as tides and rainfall totals evolve.
