Washington starts the morning under low clouds and damp pavement, with cold air sneaking quietly into Puget Sound. Headlights reflect off wet streets, and light flakes briefly mix with rain in higher neighborhoods.
According to the National Weather Service, multiple weather alerts are in effect across western Washington, including a Flood Watch, Wind Advisory, and Special Weather Statement. In Seattle, periods of rain mixed with snow are possible today and Thursday, especially during early and late hours.
Temperatures hover in the mid-40s, keeping most precipitation as rain at sea level. However, brief snow bursts may mix in, particularly in heavier showers or elevated areas. While accumulation remains minimal, slick roads can develop quickly.
The morning commute faces the greatest impact. Drivers on I-5, I-90, SR-520, and I-405 should expect reduced traction during heavier showers. Bridges, ramps, and shaded roadways may turn slippery if temperatures dip.
Winds add another layer of concern. Gusts may reach 20 to 30 mph, enough to knock down small branches and push high-profile vehicles. Loose items should be secured, and ferry riders should monitor potential delays.
By Thursday, showers continue with highs near 51 degrees. Rain and snow chances linger, though accumulations stay limited. The pattern remains unsettled through Friday, with frequent showers and chilly air holding firm.
Looking ahead to Friday, December 19, wet roads remain the main issue as Christmas travel ramps up. While a major winter storm is not expected in Seattle, colder air nearby keeps a “winter tease” in play. Any clearing at night could allow wet pavement to refreeze, raising black ice concerns.
What you can do today:
Slow down. Increase following distance. Watch bridges closely. Allow extra travel time.
