| Area Forecast Discussion National Weather Service Eureka CA 1142am PST Thu Nov 13 2025 Synopsis An area of low pressure off the coast continues to bring gusty winds to mainly Humboldt and Del Norte counties this afternoon. A few rain showers are possible today through Friday morning. Dry weather is expected Friday afternoon through Saturday. Another weather system is expected to bring rain and wind Sunday and or Monday. Dry weather returns Tuesday. The upper level low off the northern CA is continuing to bring gusty winds to northern CA. Models show this low continuing to spin off the coast through Friday morning. The models are still struggling with how quickly this low moves south and exactly how close it remains to the coast. Currently the winds are gusting from 30 to 50 mph out of the south in Humboldt and Del Norte counties with some of most exposed areas reaching 60 mph. Farther south and east winds are more like 15 to 30 mph with a few local gusts over 40 mph on the highest terrain. These are expected to diminish later this afternoon, but will remain breezy. The challenge is how strong they will be and this will depend on the exact location of the low. The rain is mainly over, but there still be some showers around through Friday morning. Friday night into Saturday high pressure briefly builds into the area. This will likely allow fog to develop quickly in the valleys. Any areas that remain clear and this may include the coast, could see frost Saturday morning. We will need to see how much things dry out. Sunday and Monday another weather system is expected to bring rain and increased winds to the area. The 24 hour rainfall amounts from the NBM show wide variations in potential amounts. The 25th percentile shows amounts ranging from the less than a 10th of an inch to barely a half in the north. The 75th percentile or higher end ranges from a half inch in the south to over 1.5 inches in the north. The max wind gusts also range from 10 to 20 mph at the 25th percentile to over 40 mph in the windy locations at the 75th percentile. Confidence is higher that we will see a short break and drier weather on Tuesday before another weather system mid to late in the week. MKK Marine Storm force gusts have ended this afternoon, but very steep and hazardous seas with Gale conditions remain. An area of low pressure responsible for these winds has weakened, but will slowly meander around the outer zones through Friday. Hazardous Seas Warnings will be required after the current Gale Warnings in the southern waters expire. A longer period west-northwest swell is very quickly building in this afternoon, mainly focused from Cape Mendocino and south. Combined sea heigheights in those zones will likely spike to around 19 ft late Thursday and into Friday morning. Latest model guidance trended the low farther east, and this will keep gale strength gusts up to 40 kts into early Friday morning for the outer zones. The Gale Warning for the norther outer zone 470 has been extended through early Friday morning. Winds and seas will quickly subside through Friday afternoon. Seas will further drop Saturday as the northerlies begin the strengthen some. A period of strong winds is looking more likely Sunday around another potent area of low pressure.
