A winter weather advisory is in effect until noon in the Cascades as snow continues to accumulate.
The National Weather Service said snow totals ranged from 8 to 15 inches in the Cascades and that 2 to 4 inches would fall by midday Monday.
The snow level is around 2,500 feet Monday morning, rising to around 4,000 feet by Monday afternoon.
Drivers encountered roads slickened by a mixture of sleet and snow, said KIRO 7 Eyewitness News reporter Rick Price.
"That means slick conditions under your foot -- or under tires," he said.
Sunbreaks and a chance of a shower are likely in the lowlands Monday, said KIRO 7 Meteorologist Morgan Palmer.
