California – Headlights barely cut through a wall of gray along the Humboldt Coast right now, where dense fog has dropped visibility to near zero miles and slowed traffic on US-101.
According to the National Weather Service in Eureka, patchy dense fog developed overnight and continues to impact travel across coastal Humboldt County, especially near Eureka and Arcata. Drivers should expect rapid visibility changes and use low beams while allowing extra time to reach destinations.
Across Eureka, Samoa, and McKinleyville, the fog lingers into late morning before partial clearing develops. Temperatures climb to around 62°F with light winds, but pockets of fog may redevelop quickly near the shoreline and bay. Roads remain damp and slick in shaded areas, increasing the risk of sudden slowdowns.
Conditions stay quiet into Tuesday with patchy morning fog again and highs near 59°F. By Wednesday afternoon, a shift begins as a 30% chance of showers develops, signaling a wetter pattern ahead. Rain chances increase further Wednesday night into Thursday, with periods of light rain and mist likely across the region.
By Thursday afternoon, steadier showers move in, creating slick roadways and reduced visibility once again. Commuters along US-101 and coastal routes should prepare for slower travel and wet conditions heading into late week.
Looking ahead, scattered rain chances continue into the weekend, keeping skies mostly cloudy and roads damp at times.
Stay alert in the fog and watch for quick changes. Are you seeing near-zero visibility where you are right now?
