| Area Forecast Discussion National Weather Service Eureka CA 1220am PST Sunday Feb 8 2026 Synopsis Rain will move in through the day Saturday and most likely end before midnight. Cool and cloudy conditions will persist through the week with additional light rain possible around Wednesday and heavier rain next weekend. Marine influence has continued to pull onshore with thick midlevel clouds currently blanketing the area. An atmospheric river is currently making landfall in Coastal Oregon with moisture very slowly pulling south. As of about midnight, some light rain showers have already impacted around Humboldt Bay with more moderate rain in Crescent City. Similar light and disparate showers will continue through Sunday morning By late morning and into early Sunday afternoon, a well defined and quick moving cold front will bring stronger and more widespread rain all across the area. The strongest rain will be focused along the the North Coast and will most likely only last a couple of hours. The general rainfall forecast has remained generally steady, if slightly earlier than previous model runs. That is to say the following totals remain most likely: 1.2 to 1.8 inches for coastal Del Norte, 0.6 to 1.0 inches for coastal Humboldt, 1.5 to 2.5 inches for higher elevation ridges, and only 0.1 to 0.3 inches for southern Mendocino and Lake Counties. High resolution models suggest some brief rain rates as high as 0.5 in/hr, but recent dry weather will greatly limit any flood concerns. Rain will end before midnight. South wind will briefly peak right as the front passes (most likely very early in the afternoon) with peak gusts around 35 mph. There is a less than 15% chance of any gusts of 45 mph, which is the usual threshold for tree or infrastructure damage. Snow levels remaining above 4500 feet during the heaviest precipitation will preclude any significant snow concerns. Colder air will quickly move in behind the front into Monday. Low and midlevel clouds will clear, but stubborn high level clouds will keep skies hazy at best into midweek. Low valley fog and clouds will prevent conditions form dropping much below freezing overnight, even in Trinity County. Models continue to show highly uncertain and weak pulse of moisture around Wednesday. Unlike todays rain, this pulse would be focused in Mendocino and Lake COunties. This potential pulse is very uncertain. There is a roughly 30% chance of no rain at all around Wednesday, but another 30% show widespread rain of 0.5 inches. Regardless, impacts would be generally minimal. Despite being further out in time, there is higher ensemble agreement (at least 80% of model members) that a stronger and more impactful storm system will impact the area around next weekend. This event would be widespread across the area but slightly focused down south. Uncertainty remains very high at this lead time, but low elevation rain amounts currently show as 1.5 to 2.5 inches with some high elevation amounts closer to 4 inches. There is a greater chance (though still only around 35%) of gusts over 45 mph with this system. Perhaps most impactful, a deep trough will bring much colder air on the back of the system around next Sunday. Current models suggest precipitation will still be falling at this time, likely generating impactful snow fall (5+ inches) for highway passes in Trinity COunty perhaps as low as 2000 feet. Stay tuned for more updates on that system. A wetter pattern will most likely stay in place until late February based on long term forecast models. /JHW Marine Overnight and Sunday: A cold front will sweep across the waters overnight and Sunday, with southerly winds increasing through the early morning hours. The most hazardous wind conditions will be concentrated north of Cape Mendocino, specifically in the northern outer waters (PZZ470), where isolated near-gale gusts up to 35 kt are expected mid-morning through early Sunday afternoon. South of the Cape and in the inner waters, gusts will remain lighter, generally peaking between 20-25 kt. Despite these wind variations, a chaotic sea state will develop across all zones as a persistent 8-11 ft westerly swell is met by building 5-7 ft southerly wind waves. These steep cross-seas will be most agitated in the outer waters and in the immediate vicinity of the Cape. Mariners should also prepare for reduced visibilities in widespread rain through the afternoon. Sunday Night and Monday: Winds will shift northerly Sunday night following the frontal passage. Northerly breezes will strengthen significantly Monday afternoon, likely necessitating the expansion of Small Craft Advisories to the southern and outer waters as steep, wind-driven seas return. To maintain clarity in hazard messaging, we will refrain from doubling up on headlines until after the current frontal passage concludes later on Sunday. /MH .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 3pm PST this afternoon for PZZ470.
