Overnight and AM Snow/Rain in Seattle is Possible, SDOT is Prepared and You can be too.

Seattle Area Forecast: Overnight and Christmas Day rain or snow showers are possible in the morning with a chance of accumulations of less than an inch from Seattle southward.

Even with this possible low accumulation of rain/snow in the forecast, SDOT is prepared and has a snow and ice response plan that is appropriate for Seattle’s weather to keep major streets open and passable to the greatest extent possible.

In Seattle, some winters bring heavy snowfall and other years see no snow accumulation at all. A weather phenomenon called the Puget Sound Convergence Zone causes some parts of the city to get inches of snow, while other parts get rain or even sun.

For your winter preparation, SDOT’s annual Winter Weather brochure is available for download online. The brochures offers a large map of Seattle’s snow and ice routes, and provides valuable travel and contact information for all who use city streets during the winter season.

Hard copy brochures are free at Seattle Public Library branches and Neighborhood Service Centers.



You can access the brochure in several languages here, including:

  • English
  • Spanish
  • Chinese
  • Vietnamese
  • Tagalog
  • Somali
  • Korean
  • Oromo
  • Tigrinya
  • Amharic

We hope you have a safe (and warm!) winter weather season!
