There's a possibility of more snow for Seattle on Sunday into Monday.
That hasn't stopped Seattle's dogs from making the most of the surprise snow day. It's also the fourth time the region has had 6 inches of snow in one day since 1991.
It was the second-largest snowfall recorded in one day in the past 20 years, only exceeded by 6.8 inches on January 18, 2012, according to the NWS.
In California, more than 120 visitors and staff members were rescued Thursday after being trapped by up to 7 feet of snow in a Sierra Nevada resort for five days.
In central Washington, blowing snow and drifts 3 to 4 feet deep forced the closure of USA 2 and Interstate 90.
Although forecasters aren't yet sure, it's possible a third snowstorm could hit Sunday night through Tuesday morning. Washington Gov. Jay Inslee declared a state of emergency Friday as the region braces for whiteout conditions, whipping winds and frigid air.
"There's a potential for more snow next week", Parker said.
"Forecasters predict this may be a storm unlike one we've seen in many years", he said.
"Travel could be very hard to impossible", the Weather Service said.
In Seattle, the city was using 34 vehicles to plows, salt and de-icing roads with 14 hand crews shuvoeling sidewalks in the center city, according to Mayor Jenny Durkan's office.
The largest amounts of over a foot of snow are possible across the Olympics and Puget Sound.
"The mountains are going to get 48 hours of more or less continuous snow", Weather Service meteorologist Steven Parker told the Statesman on Thursday afternoon.
Because temperatures are colder than normal, the snow ratios are higher than normal, Parker said. The windchill would feel like it's in the teens. Roads were slick and authorities urged people to stay home if they could while the snow was at its worst.
Officials say the combination of falling, blowing and drifting snow may lead to hard travel conditions across the region due to snow covered roads and reduced visibility.
More than 60,000 people lost power during the blizzard, which triggered major travel disruptions including hundreds of canceled flights and the closure of a 20-mile stretch of Interstate 90 in central Washington due to spin-outs and poor visibility.
People across Western Washington woke up to a fresh layer of snow Saturday, with between 6 and 8 inches in Seattle, and over 20 inches in Port Angeles.
