The state Emergency Management Division activated its operations center at Camp Murray on Wednesday to help deal with the snowstorm.
Spokesman Mark Clemens says cities and counties are handling the situation on their own, and there's been no request for state aid as of 8 a.m.
The center brings together representatives of the emergency division, National Guard, Transportation Department, Washington State Patrol and other agencies to coordinate their work.
Seattle also activated its Emergency Operations Center. Spokesman David Takami said the city Transportation Department has 33 vehicles out, focusing on keeping arterials and bus routes open. In advance Tuesday, they spread 4,000 gallons of brine and 113 tons of salt.
