Another wintery weather patter was predicted to move through Western Washington starting Saturday, with winds north of Seattle whipping to gusts of 60 mph and mountain snows.

The National Weather Service (NWS) issued a winter weather advisory for the Cascades of Whatcom, Snohomish, Pierce and Thurston counties, with an expectation of up to 18 inches of snow at pass levels through Sunday.

The Olympic range was under a winter storm watch as of Friday evening.

Areas along the coast, in the northern Puget Sound and on up into Canadian waters north of Bellingham, winds will whip Saturday night, with power outages likely in parts of Skagit, Whatcom, Island and Jefferson counties.

High winds are likely to lead to power outages in impacted areas, while mountain snow could make travel over the passes difficult.

Drivers planning to head over passes should plan ahead and stock their vehicles with water, snacks, cold weather gear (coat, hat, gloves, boots), tire chains, jumper cables, flashlight and extra batteries and, certainly, a full tank of fuel. Heavy snow can often trigger closures on Snoqualmie and Stevens passes, so drivers should check traffic status.

The Washington State Department of Transportation offers winter travel tips here, and drivers can check for travel alerts here.

Back in Seattle, rain or rain showers will likely be intermittent throughout the weekend, with a high Saturday of 47 degrees and 48 on Sunday.

Rain or rain showers in the lowlands, and snow above 3,000 feet, will likely continued at least for the next week as a "longwave trough" looks like it will persist out over the Pacific Ocean, according to the NWS.
