As we transition out of the recent stormy weather, it's important to give the snowpack time to adjust to the new load and stabilize.

Avalanche Summary
No avalanche activity has been reported. However, rider-triggered avalanches remain likely following the stormy period as the new snow will need time to stabilize and strengthen.
Please consider sharing any observations you have on the Mountain Information Network.
Snowpack Summary
The snowpack has undergone significant changes over the past week due to a series of storms, which have brought up to 100 cm of new snow at upper elevations. Freezing levels have fluctuated between 1000 and 1400 meters, resulting in variable conditions below treeline, where precipitation has been a mix of snow and rain.
The snowpack is generally 150 to 200 cm deep around treeline, with significant snow accumulation in wind-loaded areas. Snow depths rapidly decrease at lower elevations.
Various melt-freeze crusts are buried in the lower snowpack, which are not currently concerning avalanche layers.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
Problems
Storm Slabs
Several days of stormy weather have formed storm and wind slabs. They will be most problematic at high enough elevations where the ground roughness has been buried.
