Snow reroute information is available in timetables with the snowflake symbol on the front. And whenever possible Metro's public information staff will announce to the news media which routes or areas are affected.
Many radio stations announce changes in Metro service caused by snow or icy conditions.
Depending on road conditions, Metro may operate chained shuttles along hilly portions of some routes to connect with buses that can continue the routes. Other buses will follow their regular routes whenever possible, although adverse road and traffic conditions may warrant unplanned rerouting of buses to avoid hazards. If the Washington State Department of Transportation closes the Interstate 5 express lanes to general traffic, Metro may use one lane for transit only, depending on its ability to maintain the lane safely. Timetables for affected routes show alternate routing for snowy or icy conditions. When snowy or icy conditions prevail, Metro may implement reroutes any time, day or night.
