Some fresh snow in the forecast with light to moderate South West winds could create some new winds labs in the Alpine and Tree Line elevations. Choose your line with this in mind.

Snowpack Summary

A light dusting of new snow covers a sun crust on solar slopes to Mountain top. Melt Freeze crust on polar slopes up to 2200m, settled snow on north aspects above. Moderate wind effect in the ALP.

Avalanche Summary

A few small wind slabs have been observed in higher elevation leeward features.

Problems

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.
