Regions

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

Wind is in the forecast, and dry snow is available for transport.

Monitor wind direction, watch for signs of transport, and keep an eye out for wind slab development.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Dry loose avalanche activity continued through Tuesday.

Going forward, snow is available for transport so wind slabs are likely to form in lee features.

Snowpack Summary

Isolated flurries will bury a new crust formed on south aspects from strong radiation on Tuesday, and that remains soft on shaded aspects.

A crust formed after the atmospheric river is down 50 to 70 cm and facets have been observed over the crust. This layer has been reactive in snowpack tests in the crowsnest pass.

Below this, the snowpack is generally well consolidated with facets at the base of the snowpack in shallow areas near Elkford.

Weather Summary

Tuesday Night
Mostly clear skies. 20 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 1 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday
Mostly cloudy. 5 to 10 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -2 °C.

Friday
Mix of sun and clouds. 1 to 2 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Wind slabs are most reactive during their formation.

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
