Points saillants

Avalanche hazard is generally decreasing. However, uncertainty still exists regarding the reactivity of a buried weak layer that has been most prevalent on shady aspects, at treeline elevations.

    Around 30 to 50 cm of snow sits above a weak layer of surface hoar. This layer is likely best preserved in shaded and sheltered areas between 1700 m and 2000 m. Use added caution in exposed terrain due to recent west winds.

Snowpack Summary

On the snow surface, you will likely find a melt-freeze crust on southerly aspects to the top of the mountain and wind affected snow in the alpine. Small wind slabs may exist in lee terrain features formed by recent west winds.Around 30 to 50 cm of snow sits on a melt-freeze crust on southerly aspects, a crust below around 1700 m on all aspects, and feathery surface hoar in areas sheltered by the wind at all elevation bands. The surface hoar may be most pronounced on west, north, and east aspects between 1700 m and 2000 m.Below this, the snowpack is generally well-settled and strong in most locations.
