Unusual train of snowstorms to keep targeting Seattle this week

After a winter's worth of snow brought major disruptions to the Seattle area to start the weekend, the unusual train of snowstorms will continue this week with record cold bringing more hazards.

The biggest snowstorm since February 2017 brought 3-8 inches to the area from Friday afternoon to Saturday morning.

That includes 7.9 inches at the Seattle-Tacoma International Airport. The last snowstorm of that magnitude slammed Seattle in early February 2017, when the airport recorded 7.1 inches. With a total of 10.6 inches, this month is now the city's snowiest February since 1949.

Around 4 inches covered Portland, Oregon.

As the snowstorm shifts and makes travel difficult to impossible on I-5's Donner Summit this weekend and returns snow and slippery travel to Salt Lake City to end the weekend, winter will not release its grip on the Northwest.

Continued cold will set the stage for not one but at least two more snow events for the Northwest, including Seattle.

"On the heels of the early weekend storm, another can impact Washington later Sunday into Sunday night," AccuWeather Senior Meteorologist Dan Pydynowski said. "That can bring the possibility of another 1-2 inches to the Seattle area."

As quick as this snow event ends, the next in the storm train may follow and target Seattle with 3-6 inches Monday afternoon through Tuesday.

Residents will be faced with more major disruptions to travel and daily routines, including an extended stretch of school closures.

Motorists should prepare for slippery to slow and difficult travel. Even when there is a break in the snow on Monday morning, slick conditions can plague commuters as crews work to clear roads.

Flight delays and cancellations can mount during the Monday evening commute as the snow sweeps back across the city.

Travel hazards and disruptions will not just be limited to Seattle and surrounding areas. The rounds of snow into early week can also target Portland, Bend and Pendleton, Oregon; and Yakima and Spokane, Washington.

Those planning to drive along I-90's Snoqualmie Pass in Washington and I-5's Siskiyou Summit should prepare for difficult travel and potential restrictions.

The upcoming storms can produce less wind and blowing snow in Washington as the gusty winds and added travel hazards focus on areas from Oregon and Northern California to southern Idaho.

More cold and record-challenging lows can follow around midweek as western Washington and northwestern Oregon catch a break from the onslaught of winter storms.

However, there can be yet another snow or wintry mix event for the Seattle area if the cold remains in place when another storm arrives later next week.

It is not rare for snow to fall in Seattle during the winter months, but it is rare to have multiple storms bring high amounts of snow over a short period of time.

"The snowstorm spanning Friday night to Saturday morning was the second of this month in Seattle," according to AccuWeather Senior Meteorologist Brett Anderson. The first week of February started with 3-8 inches of snow in the Seattle area.

"Now the city will experience a third and then a fourth storm later this weekend into early week," Anderson stated. "I do not remember a pattern like this."

Typically, Seattle receives two to three snow events a year, or about 7 inches of snow annually. However, this can vary from little or no snow in some years to more than a foot in snowier winters.

By the middle of the new week, the snow total for this winter in Seattle may be over 14 inches. That would make this the snowiest winter at the city's airport since 2008-09, when a total of 22.0 inches fell.

Few things reflect the power of nature and weather like avalanches. This week host, Regina Miller talks to Mark Staples, director of the Utah Avalanche Center, and Dan Burnett, Group Mission coordinator for the Summit County Rescue Group in Breckenridge, Colorado. They discuss recent deaths on the slopes, the weather situations that can contribute to an avalanche, the dangers of human interaction, and how best to survive.
