We know it happens every year, it is just a matter of when the snow falls. This year it will occur on Friday, December 3, 2021, at 5:00 pm. Should you have an urgent need to use this route, please do so in advance. This will affect traffic from both sides of the pass, so make sure you are on whichever side of pass you wish to be on before then.
Alternate routes of course are Highway 2 across Stevens Pass which remains open year-round, subject to conditions. It is often closed temporarily due to extreme conditions, so check with the WSDOT before you travel any pass for current conditions.
Remember, that even if you have winter tires and studs, and 4-wheel drive vehicles, Washington State law requires you to have chains on board. If you do not, you can be turned back and/or issued a hefty fine. Never attempt a winter pass without starting with a full tank of gas in your vehicle.
As always, please be prepared for delays, stoppages, and long waits. Make sure to have emergency supplies with you. These include plenty of water, blankets for extra warmth, long lasting snacks such as energy bars and nuts. A wind-up radio is also important to keep you updated, so you are not burning fuel and/or battery power. If you have pets, do not forget them. Bring their food along and a container to give them water. If you do not want to snuggle them under your blankets, then have their own coats with you as well.
Have emergency flares with you, to alert others should you find yourself stranded on the side of the road, especially on our mountain roads, where curves are common. It can be difficult in these conditions to stop suddenly. If on a curve, place a flare before the curve, to give warning.
Stay safe and go skiing!
