Regions

Dogtooth, East Purcell.

Wind slabs may build through the day as the wind increases.

Avoid wind-loaded features.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Friday, there were several dry loose avalanches near Invermere.

On Thursday, there were numerous small, dry loose avalanches in the storm snow.

Snowpack Summary

10 to 20 cm of low-density snow covers two prominent layers:

  • A facet/crust layer buried at the end of January is down roughly 30 to 50 cm.

  • A surface hoar/crust layer buried early to mid-February is down 15 to 20 cm.

Avalanche activity on these layers has been limited and is generally small, with releases where wind loading has buried them slightly deeper.

Below this, the mid and lower snowpack are well settled with several layers of crust

Mix of sun and clouds. 2 cm of snow. 30 to 40 km/h west ridgetop wind. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Be careful as you transition into wind-affected terrain.
  • Avoid freshly wind-loaded terrain features.

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.
