Eureka, CA – The coast wakes under a blanket of fog and briny air this morning as high astronomical tides surge toward Humboldt Bay, prompting a Coastal Flood Advisory from the National Weather Service. The advisory remains in effect until 1 PM today, with minor flooding expected in low-lying coastal areas including Arcata, King Salmon, and Humboldt Bay’s shoreline parks.
Water levels are predicted to reach between 8.9 and 9.2 feet at the North Spit tide gauge, with up to 0.5 feet of inundation above ground possible near tidal waterways. Flooding could impact Jackson Ranch Road and nearby access routes. High tide hits at 11:44 AM, but forecasters warn that flooding risks begin up to two hours before and after peak tide.
Drivers and pedestrians are urged to use caution around flooded streets and avoid driving through standing saltwater, which can damage vehicles and obscure hidden debris. While this event is considered minor, it serves as a reminder that coastal flooding remains a seasonal hazard along Northern California’s shoreline as December’s tide cycles reach their highest points.
Light drizzle and patchy fog may accompany coastal flooding today, with temperatures in the mid-50s and calm winds. Scattered showers linger through early next week, keeping travel damp but manageable across the North Coast.
