Regions

Glacier.

Low hazard does not mean no hazard, unstable snow can still be found in steep and unsupported alpine terrain.

Confidence

High

Avalanche Summary

No new avalanches have been reported over the last few days. Recently the typical spring problems of wet loose avalanches and cornice failures have been occurring during warm and sunny weather.

Snowpack Summary

Below treeline, you will find a well-settled spring snowpack, with a strong surface crust that will break down during the heat of the day.

The treeline snow depth is at a record low of ~210cm. A variable crust exists on all but high northerly aspects, which still hold dry snow.

The Feb 3rd crust/facet layer persists at upper elevations, buried 80-140cm down.

Weather Summary

A weak frontal system will break the stable weather pattern with new snow and wind late on Monday into Tuesday.

Monday: Snow beginning late in the afternoon, 10cm, moderate SW winds, low -8 °C, freezing level (FZL) 1700m.

Tuesday: Snow easing through the day, 10-15cm, strong W winds, low -7 °C, FZL 2000m.

Wednesday: Mix of sun & cloud, light winds, low -7 °C, FZL 1600m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be carefull around freshly wind loaded 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.
