Regions

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

Assess steep terrain for wind slab and ride one at a time.

The best riding conditions will be found in wind-sheltered terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported since Tuesday.

Snowpack Summary

Up to 5 to 10 cm of snow is expected to have fallen on Saturday and it's likely redistributed now by strong southwest wind. This now sits on a crust on south slopes, wind-affected snow in exposed areas and hard snow in lees.

The snowpack depth varies greatly as well, windward slopes may only have 50 cm on them while leeward slopes could have as much as 150 cm.

Check out this MIN from the South Rockies Field team on Friday.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Make observations and continually assess conditions as you travel.
  • This is a good time for exploring terrain.

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.
