Regions

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

Be on the lookout for fresh wind slabs, that may be sitting atop a layer of weak faceted surfaces.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Recent snow has accumulated over previously faceted and wind-affected surfaces. Expect the current southwest wind to continue to transport the new snow into lee terrain.

At treeline and below the mid-snowpack contains a weak layer of facets over a crust.

Below, the lower snowpack contains a series of crusts and faceted snow.

Weather Summary

Monday Night

Cloudy with trace snow amounts, southwest alpine winds 30 to 50 km/h, treeline temperature -4 °C.

Tuesday

Cloudy with no precipitation, west alpine winds 30 to 50 km/h, treeline temperature -4 °C.

Wednesday

Mix of sun and cloud with no precipitation, southwest alpine winds 30 to 40 km/h, treeline temperature -5 °C.

Thursday

Mix of sun and cloud with no precipitation, west alpine winds 20 to 40 km/h, treeline temperature -5 °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.
  • Approach lee and cross-loaded slopes with caution.

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.
