Avalanche Forecast
Regions: 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.
Confidence
Moderate
Avalanche Summary
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.
Snowpack Summary
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.
