Small wind slabs may remain triggerable at higher elevations.

Even small avalanches are significant in consequential terrain.

Small rider triggered wind slabs were reported over the last 2 days. We expect reactivity in isolated wind affected features to continue.

Moderate

• We have a good understanding of the snowpack structure and confidence in the weather forecast
• Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Westerly winds have likely redistributed recent snow into deeper deposits on east and south facing slopes at higher elevations.

A prominent crust, formed in mid-December, is buried 30 to 50 cm below the surface and extends up to 2200 m. In the mid snowpack, several other crust layers exist. In the lower snowpack, a crust from mid-November can be found with facets above and below.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Recent wind has varied in direction, so watch for wind slabs on all aspects.
