Managing the winter weather. We’re working for you.

The snow is falling and a winter weather advisory remains in place until 1 PM this afternoon.

To maintain access to essential services we’ve been pretreating streets, plowing snow, and working closely with our partners. Follow our progress and see where our plows have been. View our traffic cameras on our interactive Winter Weather Response Map (for best viewing use Firefox or Chrome).


We’re working for you!

On Sunday at noon, our crews were dispatched from our Charles St, Haller Lake, and West Seattle facilities with granular salt to begin pre-treating all green and gold routes. Mechanics were called in to support operations and we coordinated with WSDOT to gain access to tunnel entrances and exits to ensure continuous pre-treatment of surfaces leading into and out of the tunnel.


We’ve been working around the clock.

We’ve been working around the clock and remain committed and on track to clearing snow from major routes throughout the city within 12 hours of a significant lull in the storm. For example, we pretreated the Aurora Bridge yesterday at noon and three times since.



  • We have over 35 plows running.
  • Drivers from Seattle Public Utilities and Seattle Parks and Recreation are assisting.
  • We’re replenishing our salt supply with 500 more tons of salt and covering all routes shown on the map.
  • We’re also working to treat curb ramps for people walking.
  • Since noon yesterday 74 drivers and 14 hand crews have checked into work. Despite this effort, there has not been a stop in the storm to allow us to completely clear.


Winter storms – here’s our plan.

Here’s how we roll:

  • Our staff follows weather reports 24 hours a day, all year long, with a direct line to the National Weather Service and live Doppler radar feeds.
  • We use a forecasting tool developed with the University of Washington called SNOWWATCH to learn how a storm will most likely affect different neighborhoods. This information helps determine where the crews will be needed first.
  • Our computerized sensors located on city bridges, and also ground surface sensors, provide timely and accurate air and roadway surface temperatures.
  • We use real-time, live-streaming cameras to see actual conditions on key streets.
  • The City of Seattle takes a proactive approach, using best practices to respond to snow and ice:
    • SDOT crews use trucks fitted with plows and salt-spreaders to keep major streets clear.
    • When conditions allow, the crews’ pre-treat key streets and bridges with salt brine before the snow starts falling to help prevent ice from forming.
    • As the snow begins to fall, the crews continue to drive their routes, treating the roadway with salt brine or granular salt where needed. When approximately one inch of snow has accumulated, they begin plowing.


We rely on you as well. Delay your trip if you can. Plus safety tips.

During major winter storms, plan your trip by seeing where the snow plows have been and viewing traffic cameras. View the interactive Winter Weather Response Map

✔️ Drivers

If you need to drive, please take extra care when traveling. Clear your vehicle’s windows, drive slow, and if you need to stop, move out of active travel lanes. If driving is unavoidable, you’re responsible for outfitting your cars for winter weather, including chains or other traction devices.

Remember, while snow is forecasted to taper off, temperatures will stay cold and streets have the potential to be slick.
