Before venturing into steeper terrain, carefully evaluate for the presence of wind slabs.

Avalanche Summary

No recent avalanches have been reported.

Data in this region is limited. Please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Surface snow has been redistributed by recent strong west winds, creating various wind-affected snow surfaces at higher elevations.

There is a prominent crust down 30-60 cm.

The average snow depth at treeline varies widely from 50-100 cm, with the deepest snowpack around the Fernie area. Snow depth tapers rapidly below treeline.

Weather Summary

Thursday Night

Mostly cloudy with no precipitation, southwest alpine winds 10 to 30 km/h, treeline temperature -4 °C, freezing level 1300 m.

Friday

Sunny with no precipitation, southwest alpine winds 0 to 20 km/h, treeline temperature 0 °C.

Saturday

Partly cloudy with no precipitation, south alpine winds 0 to 20 km/h, treeline temperature 0 °C with above freezing temperatures in the alpine.

Sunday

Mostly cloudy with no precipitation, southwest alpine winds 10 to 20 km/h, treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • 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.
