For anyone one planning on traveling in the Central Cascades next week, Blewett Pass is going to be closed from Sunday Night 9/9 @ 9PM and won't re-open until Friday AM 9/14 at 9AM. Throughout the entire month of September there will be 1 lane closures and accompanying delays.
Looks like Chinook is closing early this year. I'd be surprised if they get this open before the hard snow fall begins. https://www.wsdot.wa.gov/travel/highways-bridges/passes/chinook-and-cayuse/home
