EUREKA, CA — Northern California is experiencing a chilly start to the week as a Frost Advisory and Beach Hazard Statement are currently in effect. Temperatures have plunged into the 30s in inland areas, with frost covering lawns, windshields, and fields along the coast. The National Weather Service in Eureka has warned that the Humboldt and Mendocino coasts are at a heightened risk for dangerous sneaker waves through Tuesday morning.
Residents from McKinleyville to Arcata are advised to protect sensitive plants and keep pets safe from frost-related damage, as morning lows around 36°F pose a threat to tender vegetation. Drivers should also exercise caution, as these low temperatures can lead to slick patches on bridges and shaded roads, necessitating more time for visibility and traction issues.
On the coast, large, unpredictable waves may surge ashore unexpectedly, drawing in debris and posing a risk to unsuspecting beachgoers. Meteorologists highlight that calm seas can be misleading; sneaker waves often occur after a period of quiet surf, and the greatest risk is present along the Del Norte, Humboldt, and Mendocino County coastlines until 8 a.m. on Tuesday.
Looking ahead, Tuesday afternoon is expected to bring mostly sunny skies with temperatures rising to around 56°F. As the week progresses, dry weather will persist through Thursday, but clouds will increase by Friday as the next Pacific system begins to develop offshore, suggesting a shift in weather patterns for early December.
With the promise of warmer temperatures on the horizon, residents can take heart that conditions will improve, offering opportunities for outdoor activities as the week unfolds.
