Eureka, Calif. – Drivers across Northern California should prepare for patchy fog Tuesday morning, September 2, especially along Highway 101 near Eureka. Reduced visibility could create delays for morning commuters, with conditions expected to ease by late morning. Officials urge drivers to slow down, keep headlights on, and allow extra travel time.
According to the National Weather Service in Eureka, patchy fog will linger along the coast through Friday, while inland areas remain mostly cloudy. Temperatures will stay mild, with highs near 64 to 65 degrees through midweek. Winds from the north will pick up slightly Tuesday afternoon, bringing cooler air and calming by evening.
In Eureka and nearby towns such as Arcata and Fortuna, skies will stay mostly cloudy during the day, with overnight lows hovering around 54 to 55 degrees. Calm winds and marine layers may keep conditions damp, particularly in low-lying neighborhoods near Humboldt Bay. Residents should keep dehumidifiers or fans running to reduce indoor moisture.
Travelers along coastal roads should expect visibility to drop sharply in the mornings, especially near river valleys and shaded stretches of Highway 101. Local agencies advise avoiding sudden lane changes and maintaining safe distance when fog thickens.
The foggy stretch also signals the start of meteorological fall, bringing more stable weather and cooler nights. While no major storms are forecast this week, lingering coastal fog could complicate morning commutes and outdoor plans through the weekend.
