SEATTLE -

A significant weekend storm disrupted plans across the Northwest U.S., blanketing parts of Washington state with snow, socking Oregon and California with rain and contributing to the deaths of three people.

In the Seattle area, several inches of new snow overnight brought a flurry of snowman-building, sledding and other winter fun before Monday when the forecast called for rain and milder temperatures into the rest of the week.

 By Sunday, nearly 3 inches fell at Seattle-Tacoma International Airport, the heaviest snowfall in a single day at that location in about two years. Parts of southwest Washington got hammered with as much as 5 inches or more in south Thurston County and some parts of Lewis County.

  High avalanche danger prompted officials at Mount Rainier National Park to close the gate to Paradise at Longmire on Sunday.
