Haines Pass

Significant snowfall and strong winds are expected to form reactive slabs.Stick to conservative terrain and avoid overhead hazard until the new snow has had a chance to stabilize.

Field observations have been limited due to road closures, if you're out in the backcountry please consider submitting your observations to the Mountain Information Network.

Up to 35 cm of combined new and recent snow is expected to fall by end of day Saturday. This snow covers old, firm, wind-affected or wind-scoured surfaces. Strong southeasterly winds will likely form reactive new slabs that may not bond well to the old surface.

The midpack is generally strong and bridges the weak crystals at the base of the snowpack.

• Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
• As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.
• Be especially cautious as you transition into wind affected terrain.
