10/11/2025, 2:45:29 PM
Upcoming Weather Conditions
Seattle is bracing for a weekend characterized by scattered showers and cooler temperatures, with highs expected to reach the mid to upper 50s. A Winter Weather Advisory and Storm Watch will be in effect from Sunday morning through Monday morning, predicting significant snowfall in the mountains, particularly in Whatcom and Skagit counties, where accumulations could reach up to 7 inches above 5,000 feet. The forecast indicates that conditions will improve by Tuesday, with dry skies and sunshine anticipated through midweek.
Friday saw a mix of scattered showers and cooler temperatures, with highs only in the low to mid-60s. The Mariners playoff game on Friday evening may require a closed roof due to rain, although conditions could dry out by game time. Snow levels are expected to drop over the weekend, with the potential for light snow at lower elevations, particularly at Stevens Pass and Snoqualmie.
Traffic Disruptions Due to Construction
Travelers in the Seattle area should prepare for significant traffic disruptions this weekend due to major construction projects coinciding with several large sporting events. Starting late Friday, October 10, southbound Interstate 5 over the Ship Canal Bridge will be reduced to two lanes until early Monday morning. This lane reduction is part of ongoing repairs to the aging bridge, which has not undergone significant preservation efforts in 40 years. The Washington State Department of Transportation (WSDOT) has indicated that these lane reductions will continue on specific weekends through January 2024.
In addition, southbound Interstate 405 will be closed between Coal Creek Parkway Southeast and Northeast 30th Street for paving and drainage work. WSDOT advises travelers to allow extra time for their journeys, consider alternate routes, and utilize public transit where possible.
Official Statements & Responses
WSDOT's Northwest region administrator, Brian Nielsen, stated, “We coordinate our work with the various teams and venues to ensure that most of the traffic can clear before the lane reductions go into effect.” The agency is focused on completing necessary repairs before the onset of rainy fall weather.
Criticism & Opposition
Concerns have been raised regarding the timing of these construction projects, particularly as they coincide with significant local events, including the Mariners playoff game and other sporting activities. Critics argue that the lack of coordination between construction schedules and major events could exacerbate traffic issues and inconvenience residents and visitors alike.
What's Next
As the weekend progresses, Seattle residents can expect continued wet weather, with a return to drier conditions by midweek. Travelers should remain vigilant regarding traffic updates and plan accordingly to navigate the expected disruptions on major roadways.
