Avoid wind loaded features.

Wind slabs are expected to be poorly bonded to the underlying layers, human triggering is likely.

Moderate

• We have a good understanding of the snowpack structure and confidence in the weather forecast.

On Monday and Tuesday, explosive control work produced size 2 wind slabs with evidence of a previous natural cycle on reverse loaded features.

Reports in this region are limited, please post any photos or observations to the MIN if you head out.

Up to 20 cm of recent snow, accompanied by southwest wind, has formed deep deposits on north and east aspects. This new snow sits over firm, wind affected snow and facets. On windward aspects alpine terrain could be scoured back to a crust.

The January 26                crust is buried 50 to 100 cm deep below 1350 m. Surface hoar may linger above this layer on sheltered north to east aspects. Human triggering is considered unlikely.

Facets or depth hoar exists at the base of the snowpack and may be a concern in areas with a shallow snowpack, such as inland terrain.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Recent strong wind means wind slabs may be found farther downslope than expected.
• Be alert to conditions that change with elevation, aspect, and exposure to wind.
