| Area Forecast Discussion National Weather Service Eureka CA 247pm PDT Sat Mar 21 2026 Synopsis Dry weather and above average inland temperatures will persist into next week. A weakening front will bring a quick chance for rainfall and a period of increased southerly winds. Otherwise, dry and warm weather will persist. A weak front passed through the region and brought some accumulating light, coastal drizzle and persistent low clouds over Humboldt and Del Norte counties. Breezy northerly winds developed behind the front. High temperatures are greatly reduced over the interior behind the front as the embedded Desert Southwest ridge of high pressure weakens. Surface pressure is nosing in from the west, and will work to maintain above average inland temperatures. Areas in Southern Mendocino and Lake County will continue to see high temperatures in the high 70s to low 80s, brining some minor HeatRisk. A stronger front will push into the Pacific Northwest early next week, with a trailing portion clipping Northern California. Precipitable water values will be anomalously high (200% above normal), but the front will likely struggle to maintain strength as it descends south against the southern ridge Tuesday through Wednesday. Southerly winds at 925 mb (near 2000 ft) will increase with the front Tuesday. This may bring a period of breezy conditions to some of the North Coast and interior ridges. Probabilities for total rainfall in Del Norte County are only 40%, but a brief period of higher rainfall rates will still be possible is the front maintains better strength. NBM 90% (worst case) 24 hour rainfall does not reach an inch however. Dry warm weather will otherwise persist under high pressure. The next hint of a pattern change toward wetter weather does not arrive until near the end of the month. Marine Very hazardous ocean conditions are forecast this weekend. North wind gusts from 34 to 42 kt are highly probable (>80% chance), primarily over the outer waters and inner waters south of Cape Mendocino. A gale warning is in effect. A long fetch of strong northerly winds will generate very steep waves from 10 to 15 feet with periods from 8 to 10 seconds by Saturday afternoon and evening. Waves this large and steep will be capable of capsizing small vessels and mariners are encouraged to remain in port. A hazardous seas warning has been issued for northern inner waters with very steep waves forecast to build to 10 ft or more Sat evening and Sat night. These very steep waves will continue Sunday morning. A secondary ramp up in very steep waves will occur Sunday afternoon and evening for the inners. For the outers, waves will remain very steep and treacherous through at least early Monday morning. Outlook going into next week: Conditions will begin to ease up and subside on Monday with lower seas into Tue. Conditions deteriorate again around mid week as a large mid period W-NW swell arrives and potential for northerly gales increases after frontal passage. .EKA WATCHES/WARNINGS/ADVISORIES... CA...
