Snowpack Summary

The snowpack in the alpine is starting to increase and some alpine areas have enough snow for avalanches to occur. Wind loaded slopes, and steep narrow gullies are the highest concern.

Avalanche Summary

Occasional reports of natural avalanches up to size 1.5 in steep alpine terrain have been observed during strong wind events.

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
