This is from a 963 Mb low that will move up the coast from Northern California

The significant wave height is the average of the largest One Third. One in 1,000 waves will be TWICE the significant height. With a 15-second period that means one wave every four hours will be twice the significant height or over 50' for most of Saturday and Sunday. And over 35' from Thursday afternoon to Monday morning.
