Avalanche Summary

No new avalanches have been observed or reported. Explosive testing on Monday near Fernie did not produce any results,.

Snowpack Summary

40 to 60 cm of snow remains soft in sheltered areas, but may have formed slabs in leeward aspect terrain. A melt freeze crust exists near the ground but is unreactive.

Total snow depths vary from 100 to 150 cm at treeline.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

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.
