Eureka drivers should prepare for slick roads and possible traffic slowdowns on U.S. 101 as a wet weather pattern builds by Monday. Stronger systems arrive late Sunday into Monday, making travel difficult during the morning rush.
According to the National Weather Service, widespread showers are expected across Humboldt County beginning Sunday night, September 28, with rainfall likely to intensify by Monday morning, September 29. Breezy south winds will add to the hazards, especially along coastal stretches of U.S. 101 and Highway 299.
Monday’s rain could drop between a quarter and three-quarters of an inch, raising the risk of hydroplaning and poor visibility. Drivers are urged to allow extra time for commutes, reduce speed in wet conditions, and keep headlights on for safety. Power interruptions are possible if stronger gusts combine with saturated soil.
The stormy setup lingers through Tuesday and Wednesday, keeping Humboldt County wet into the start of October. Gusty winds Tuesday could make conditions especially challenging for high-profile vehicles crossing bridges or exposed routes. Residents should secure outdoor items and prepare for repeated rounds of showers.
Temperatures will hold steady in the low to mid-60s during the day and 50s at night, typical of early fall patterns. Sunshine may return by late next week, offering a brief break from the unsettled stretch.
Rain chances remain elevated through midweek, and additional advisories may be issued if conditions worsen.
