Regions

Kananaskis.

Sunday could bring a significant storm with lots of wind. Extensive wind slab development is likely at upper elevations. Avoid avalanche terrain.

Confidence

Moderate -

Weather Forecast

Sunday will see the arrival of a significant storm for the region. Up to 30cm of snow is possible with SW winds peaking at 125 km/h at mountain top. Freezing levels will be near 2000m. Monday could see an additional 15cm of snow with slightly slower wind speeds.

Avalanche Summary

No new avalanche were observed today.

Snowpack Summary

Moderate to strong winds continue to move snow around, especially at higher elevations. Alpine areas and open treeline terrain are heavily wind affected. Wind slabs are prevalent in lee and cross-loaded terrain, and the forecasted storm on Sunday will create fresh wind slabs. Thankfully the midpack and basal layers are uncharacteristically strong and dens for this time of year.

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Watch for areas of hard wind slab on alpine features.
  • Ice climbers should be equipped with avalanche safety gear.
  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.

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.
