The alpine rating is Storm Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeFresh snowfall continues to accumulate, leading to the formation of new slabs. Seek out low-elevation terrain that is less impacted by the strong alpine winds.

Avalanche Summary
No recent avalanche activity has been reported. Natural avalanche activity is likely over the coming days, particularly in regions receiving higher snowfall amounts.
Observations remain very limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network
Snowpack Summary
New snow continues to form reactive wind and storm slabs at the surface. The recent snow has buried a variety of surfaces, including old wind-affected surfaces, along with a chance of surface hoar or faceted crystals in wind-sheltered terrain.
A crust formed in early November may be present in the mid-snowpack, with possible faceted crystals above or below it.
The lower snowpack is largely comprised of several old melt-freeze crusts and potentially large depth hoar crystals in some areas.
Snowpack depth at treeline is roughly 100 cm, with snow depths decreasing rapidly at lower elevations.
Weather Summary
Thursday Night
Cloudy with 10 to 20 cm of snow, local values around Pine Pass and to the north may see less accumulation. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.
Friday
Cloudy with 10 to 20 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.
Saturday
Cloudy with 5 to 15 cm of snow. 40 to 60 km/h south ridgetop wind. Treeline temperature -12 °C.
Sunday
Cloudy with 5 to 15 cm of snow. 40 to 60 km/h south ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice
- Watch for fresh storm slabs building throughout the day.
- As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
- Sheltered slopes at lower elevations will offer the safest conditions.
- Be cautious of buried obstacles, especially below treeline.
Problems
Storm Slabs
New snow continues to accumulate, resulting in reactive storm and wind slabs. These slabs are of greatest concern at higher elevations where winds are much stronger.
