The National Weather Service warns of southeasterly winds 30 to 45 mph, and gusts of 50 to 60 mph, to include the shores of Whidbey Island and the San Juans. High winds can knock down trees and cause power outages.

Cliff Mass’ weather blog describes the gathering storm as a “major cyclone” that could generate 100 mph winds offshore from Vancouver Island, and might cancel Victoria Clipper passenger service Monday.

He encourages storm enthusiasts to go see waves forecast to be from 26 to 29 feet along the Olympic Peninsula coastline.

Meanwhile, the snow level will drop to 3,200 feet at Snoqualmie Pass (elevation 3,022) by early Sunday, and several inches of snow are likely until Wednesday night in the central Cascades, the weather service says.

Rain will fall in the Seattle area most of Sunday and Monday, with highs in the mid-40s both days.
