Regions

South Rockies, Akamina, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Conditions are generally safe, but small wind slabs may be possible on steep slopes.

Confidence

Moderate

Avalanche Summary

The last reported avalanche was a size 2.5 wind slab triggered with explosives on Thursday.

Snowpack Summary

Westerly winds have heavily impacted the snowpack, scouring windward slopes and forming isolated wind slabs on leeward slopes. Wind slabs could overlie facets. Wind effects are most pronounced in Alberta.

The lower snowpack has no concerning layers.

Treeline snowpack depths range from 50 to 150 cm across the region.

Terrain and Travel Advice

  • This is a good time for exploring terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
