Regions

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

Avoid locally deep spots where wind slabs may have formed.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported at the time of publishing on Saturday.

Snowpack Summary

Up to 5 cm of new snow sitting over crusts on solar aspects, surface hoar, wind-affected snow, and facets.

The snowpack contains a couple of thick, hard crusts buried 10 to 20 cm and 30 to 70 cm deep. The snowpack has no weak layers below.

The snow depth at treeline is 50 to 130 cm.

Snow depth decreases rapidly at lower elevations.

Weather Summary

Saturday Night

Mostly cloudy with 5 to 10 cm of snow, southwest alpine wind 10 to 20 km/h, treeline temperature -10 °C.

Sunday

Mostly cloudy with up to 5 cm of snow, alpine wind calm to 15 km/h from various directions, treeline temperature -15 °C.

Monday

A mix of sun and cloud with no new snow, west alpine wind 15 to 25 km/h, treeline temperature -13 °C.

Tuesday

A mix of sun and cloud with 5 to 10 cm of snow, west alpine wind 40 to 60 km/h, treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.

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.
