Continually assess conditions throughout the day.

Conditions will vary from aspect to aspect and from morning to afternoon.

Moderate

• We are uncertain about alpine conditions due to limited field observations.

Natural wind slabs have been observed over the past few days to size 2. However most activity was noted to be size 1, with limited propagation.

Up to 30 cm of new storm snow can be found at treeline and above. This snow was accompanied by southerly wind, likely forming deeper deposits on north aspects. The snow surface is expected to become moist early in the morning on sun exposed slopes.

Average treeline snow depth is 70 to 150 cm. The snowpack depth tapers rapidly with elevation, especially on south facing slopes.

• Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
• Be alert to conditions that change with elevation and sun exposure.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
