SNOQUALMIE PASS, Wash. —
The avalanches occurred as heavy snow fell near Snoqualmie Pass.
Kenny Kramer, director of Northwest Weather and Avalanche Center, said between 20 and 30 inches of snow fell over the weekend and the center warned of dangerous avalanche conditions.
“We had a considerable danger,” the meteorologist said Sunday. “We were expecting a lot of snow.”
All that new snow was weakly attached to the old snow crust, making it more unstable, Kramer said.
Avalanches during the spring aren’t a rare occurrence, he said, noting that there’s a secondary peak of incidents during this time because the Northwest still sees winter-type storms that brings lots of snow. When that snow falls in the spring, it often warms up quickly, creating unstable conditions, he said.
