Metro Transit is warning travelers to prepare for snow and delays:
Some Metro buses might chain tonight; crews on standby to plow roads
Snowfall is in the forecast in parts of King County for Monday evening, and the King County Department of Transportation urges Metro Transit customers and water taxi riders, as well as people who travel unincorporated county roads, to monitor weather conditions and plan for possible travel delays.
At the moment, a National Weather Service winter weather advisory is in effect for north of Seattle and east to Bellevue. Metro Transit continues to monitor weather conditions as they evolve and crews are prepared to adjust service where needed.
In areas where snow accumulates Monday night, Metro is prepared to chain buses for routes and trips after 8 p.m. Riders might see chained buses traveling outside of snow areas depending on their assigned routes.
Buses might also shift to snow routes as needed, or coordinate with special shuttles equipped with tire chains to connect riders in hilly or difficult-to-access areas with transit service on major corridors. If Metro activates snow routes, email and text transit alert subscribers will receive notifications and information will be posted to Metro’s Snow and Ice page.
Overnight, Metro will monitor weather conditions and determine what routes require chains for the Tuesday morning commute.
Earlier Monday, Metro made changes to its trolley fleet operations as a precaution. Articulated 60-foot-long buses are the workhorses of Metro’s fleet, however the 60-foot-long articulated electric trolley buses were temporarily grounded due to the expected inclement weather – a regular measure for Metro with its trolley fleet due to difficulty operating in snow conditions. Some bus trips were temporarily canceled Monday morning and afternoon in order to shift buses to serve those electric trolley routes. Metro will continue to evaluate when it is safest to return the 60-foot-long articulated electric trolley fleet to service depending on weather conditions in Seattle.
