The National Weather Service says the region is facing combined risks of flooding, landslides and toppling trees before things calm down for a drier weekend.
Another 3 to 6 inches of rain are forecast in the Olympics and 2 to 4 inches in the North Cascades. With a high snow level, the runoff could flood rivers flowing off the mountains. Mudslides are possible on saturated bluffs and steep hills.
Trees could topple in soggy soil in Thursday’s winds. Forecasters are warning of 35 mph to 45 mph winds with gusts to 75 on the coast and northwest interior. Forecasters also are watching for winds in the urban Puget Sound area of 30 mph to 40 mph with gusts to 65.
