| Area Forecast Discussion National Weather Service Eureka CA 238pm PDT Monday September 28 2026 .KEY MESSAGES... * High pressure builds through the rest of the week, bringing an extended dry period with interior valley high temperatures warming into the 80s and 90s. * An arriving long-period west-northwest swell brings an elevated risk for sneaker waves along beaches today. Synopsis Upper-level ridging builds over the West Coast this week, supporting a progressive inland warming trend and dry conditions through this coming weekend. Broad mid-level ridging over the eastern Pacific will expand inland Tuesday through Friday, establishing high confidence in dry conditions across the region. At the surface, the onshore pressure gradient between the offshore eastern Pacific high and the interior thermal low will drive fresh northerly winds along shore, strongest south of Cape Mendocino. Additionally, conditions will be gusty for many locations across Northwest California. Gusts greater than 20 mph could be possible this afternoon/evening and tomorrow afternoon/evening with an 80% chance or higher for coastal areas from Del Norte to Mendocino, and more widespread chances for all of southern Humboldt and most of Mendocino and Lake counties, and for the ridges of Del Norte and Trinity counties. There is an 80 percent chance or higher for gusts over 25 mph today and tomorrow for all coastal areas along with the King Range, with more widespread chances for Tuesday afternoon/evening. Strong atmospheric sinking beneath the upper ridge will steadily warm the air mass aloft. Thermal profiles across interior valleys will support afternoon maximum temperatures climbing into the 80s and 90s mid-week. Ensemble guidance highligheights an 80% probability of interior valley highs exceeding 90°F Wednesday and Thursday. Marine Fresh northerlies continue due to the pressure gradient between offshore high pressure and the interior thermal trough. * Northern Inner Waters: Northerlies of 10 to 20 kt will generate steep short-period seas. A west-northwest swell at 15 to 17 seconds arrives today. A Small Craft Advisory remains in effect through Tuesday morning. * Northern Outer Waters: Northerlies of 20 to 25 kt with gusts to 35 kt (mainly in the lee of Cape Blanco) will build combined seas to 10 to 11 ft. A Small Craft Advisory remains active through Tuesday morning. * Southern Inner Waters: Fresh to strong northwest winds of 20 to 25 kt with gusts to 35 kt (mainly in the lee of Cape Mendocino) will maintain steep seas. A Small Craft Advisory remains in effect through Tuesday morning. * Southern Outer Waters: Gale force conditions develop in the lee of Cape Mendocino, where northerly winds of 25 to 30 kt with gusts up to 40 kt will yield steep, hazardous combined seas of 11 to 12 ft. A Gale Warning remains in effect this afternoon through Wednesday morning. .BEACH HAZARDS...A long period west northwest swell at 3 to 6 ft with a period up to 17 seconds will build in today. This swell will bring a moderate risk for sneaker waves. A smaller 3 ft long period south swell will also bring some risk for sneaker waves for south facing beaches. High astronomical tides will increase the danger, especially over rocks and jetties. Sneaker waves are a unique hazard, with up to 30 minutes between waves. Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. These sneaker waves can also move large objects such as logs, crushing anyone caught underneath. Even ankle to knee deep water can knock you down and drag you out when a sneaker wave hits. Pay attention and stay above the high water line and any wet sand to stay safe. If the ground is wet, waves have surged. .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 9am PDT Tuesday for PZZ450-470. Small Craft Advisory until 9am PDT Wednesday for PZZ455.
