EUREKA, Calif. – Drivers along Highway 101 should prepare for reduced visibility Friday and Saturday mornings as thick fog blankets the Humboldt coast. Sunshine breaks through during the afternoons, but the National Weather Service warns of rapid changes for anyone traveling near the bay or on coastal routes.
According to forecasters, patchy fog forms before 11 a.m. Friday, with afternoon highs near 64 degrees under mostly sunny skies. Winds may gust up to 20 mph, creating choppy conditions for boaters near Humboldt Bay. Saturday brings similar patterns—dense fog early, then bright skies. Travelers should slow down on Highway 101 and keep headlights on in low-visibility stretches.
The weather shifts late Sunday as clouds thicken and the first rain of the season approaches. A chance of showers develops Sunday night, with rain likely Monday and lingering into Tuesday. Daily highs stay in the low 60s, while overnight lows dip into the low 50s. By early October, steady rainfall may impact commutes and bring the first real taste of fall to Northern California.
Residents are urged to charge devices ahead of potential power disruptions and allow extra travel time when fog reduces visibility. Boaters and coastal visitors should watch for sudden wind changes through the weekend.
More advisories may follow as Monday’s storm system develops.
