Regions

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

Lingering wind slabs may remain reactive to human triggers on lee aspects in the alpine. Don't commit to steep slopes where snow feels dense or stiff.

Confidence

Moderate

Avalanche Summary

Several dry loose avalanches up to size 1.5 in neighboring regions out of steep terrain features on Tuesday.

Snowpack Summary

Recent snow has accumulated over a crust at treeline and alpine elevations. On the east side of the region, there is 20 to 40 cm, and on the west side 10 cm on this crust.

Below this crust, the shallow faceted snowpack is moist and starting to refreeze with cool temperatures. Two crust layers, one in the midpack and another near the base of the snowpack continue to be monitored. Avalanches on these layers are unlikely.

Weather Summary

Wednesday Night

Mostly cloudy. Alpine wind 5 to 10 km/h northwest switching to west. Treeline temperature -7 °C

Thursday

Cloudy with scattered flurries beginning late afternoon with 5 to 8 cm accumulation into Friday morning. Alpine wind southwest 10 to 20 km/h. Treeline temperature -5 °C.

Friday

Mainly cloudy with isolated flurries 1 to 2 cm accumulation. Wind northwest 10 to 20 km/h. Treeline temperature -9 °C.

Saturday

Cloudy with sunny breaks. Wind southwest 20 to 25 km/h. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.

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.
