Eureka, Calif. – Drivers in Humboldt County should prepare for reduced visibility and slick pavement Saturday morning as fog and rain move into the Eureka area. Travel along U.S. Highway 101 could be slow, especially between Arcata and Fortuna, where early-morning fog is likely to be thickest.
According to the National Weather Service, a 50 percent chance of rain will develop before 11 a.m. Saturday, August 16, with patchy fog earlier in the morning. Calm winds will turn north at 6 mph by afternoon, keeping high temperatures near 64 degrees. Showers may return Saturday night before skies clear.
Sunday will bring a welcome break with mostly sunny skies and highs in the low 60s, but patchy fog returns Monday morning. Temperatures will stay mild, keeping energy demand low but requiring morning commuters to use headlights and caution.
Residents should keep umbrellas and jackets handy for early Saturday activities, allow extra travel time, and check conditions before heading out. Wet roads may be slippery, particularly near the coast.
More sunshine is expected early next week, though morning fog could remain a factor for drivers along U.S. 101. Another update will be issued if additional rain chances develop.
