California’s North Coast greets the morning with gray skies, damp pavement, and tidewater pressing into Humboldt Bay. Water laps higher than normal along docks and shoreline roads, creating brief but noticeable flooding concerns as the tide peaks.
According to the National Weather Service in Eureka, a Coastal Flood Advisory remains in effect through late morning as high astronomical tides bring minor flooding to low-lying areas around Humboldt Bay. Forecasters warn saltwater inundation of up to half a foot above ground level is possible near shorelines and tidal waterways.
The highest impacts are expected in northern Humboldt County, including Eureka, Arcata, and King Salmon. Flooding may affect waterfront parks, parking lots, and sections of local roads. Officials specifically note Jackson Ranch Road in Arcata Bottoms and several low spots in King Salmon as areas to watch closely. Only isolated road closures are anticipated, but drivers should remain alert.
Travel near the bay could slow during peak tide. Standing water may obscure road edges, and visibility stays reduced at times under low clouds. Avoid driving through water of unknown depth, and protect vehicles and property near the shoreline.
Away from the coast, conditions improve steadily. Showers taper early, then skies trend brighter as the day progresses. Temperatures remain seasonable, with highs near the upper 50s before a warming trend settles in for the first half of February.
By Tuesday, sunshine dominates and daytime highs climb into the low 60s. Midweek brings even milder afternoons, offering a calm stretch after the morning flooding risk fades. No additional coastal advisories are expected once tides recede, but February patterns can shift quickly.
