Regions

South Rockies, East Purcell, Bull, Elkford East, Elkford West.

Expect challenging travel conditions; cool temperatures will limit the crust softening.

Assess consequential lines for wind slab before dropping in.

Confidence

High

  • Confidence is due to a stable weather pattern; little change is expected for several days.

Avalanche Summary

No new avalanches have been reported since Wednesday. Avalanches remain possible at higher elevations, where wind slabs may linger. Otherwise, avalanche activity is unlikely where a thick surface crust exists.

Snowpack Summary

A crust exists to mountain top on south aspects and treeline on others, with dry, wind-transportable snow lingering on high north slopes.

40 to 60 cm of snow sits over surface hoar in sheltered areas and a sun crust on steep south slopes; this layer has been inactive and is unlikely to react where the crust is thick. A deep melt-freeze crust with facets persists in shallow snowpacks and remains dormant but could reactivate with significant snowfall or warming.

Weather Summary

Sunday Night
Clear skies. 20 km/h northwest ridgetop wind. Treeline temperature -7 °C.

Monday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -6 °C. Freezing level 300 m.

Tuesday
Mostly sunny. 30 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Wednesday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • This is a good time for exploring terrain.
  • Make observations and continually assess conditions as you travel.

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.
