Avalanche Summary

No avalanches reported or observed.

Snowpack Summary

This season's snowpack is shallow and facetted. Eastern areas have very weak snowpacks (sometimes not holding the weight of a skier) while areas further west are stronger, even while still being mainly facets. Snow depths at Treeline range from 60 to 120cm. The early season crusts at the base of the snowpack have largely broken down. In isolated locations in the Alpine there are pockets of wind slab. These may be more sensitive to triggering in steep and unsupported terrain.

Weather Summary

Wednesday will see a mix of sun and cloud, A day time high of -8 with winds firmly in the Moderate range (40km/h).

And of course, no snow in the forecast.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Avoid steep terrain that is rocky and thin.

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.
