Hazardous marine conditions return this morning and continue through the weekend. A weak storm system has arrived, bringing light rain and moderate to strong winds with strong to near gale force gusts. Gale force gusts are possible as frontal passage occurs but, given the speed of the cold front, they are expected to be short lived with winds diminishing quickly. Winds diminish by early Friday with moderate northerly winds expected into next week. Seas build to 10 to 15 feet Thursday and remain elevated into early next week. Elevated seas will be prolonged by the arrival of two distinct rounds of long period northwesterly swell. $$ PZZ570-202315- Waters from Point Arena to Point Reyes 10-60 NM- 235 AM PST Thu Nov 20 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH FRIDAY EVENING... .TODAY...NW wind 20 to 25 kt.
