Regions

Kananaskis.

Although Mod/Low/low gives confidence in approaching larger features, assess each individual feature and make an informed decision. Great skiing can still be found in Sheltered alpine all the way to the valley floor.

Weather Forecast

Tomorrow will have a high of -9, cloudy sky's and SW winds in the 40-50km range. models don't agree in snow amounts, from trace to 5cm.

Looking forward, Monday and Tuesday should be a nice reset with current predictions in the 20-30cm range

Avalanche Summary

Forecasters out in the terrain, travelling on E aspects today got some settlements in steeper planner Alpine features. They turned around and skied a more supported line, Snow quality was slightly wind affected but skied just fine. 

2 Windslabs Sz 1.5 out of E aspects at treeline above the highway by tent ridge today, These are with in the last 24hrs. 

Snowpack Summary

Recent storm snow has settled to 10-20cm on southern aspects. It remains light and dry with some light wind effect. North aspects are much more wind effected at tree line and alpine elevations. Overall the surface snow feels facetted and weak, even in areas that have received wind. Wind slab character varies greatly and is tricky to predict.

Terrain and Travel

  • Be alert to conditions that change with elevation and wind exposure.
  • Wind slabs may be poorly bonded to the underlying crust.

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.
