Regions

Waterton Lakes, Waterton.

Additional snowfall accompanied by moderate winds will continue to build wind slabs. Use caution around ridge crests and in wind-loaded terrain features.

Avalanche Summary

Several natural wind slab and wet loose avalanches observed over the past few days.

Snowpack Summary

Our current snowfall sits on top of 10 to 40 cm of snow, from this past weekend. At lower elevations this layer is moist, due to recent rainfall. Under this, is up to 40 cm of wind effected snow.

The melt freeze crust from late December can be found 40-70 cm deep.

The middle and lower snowpack consists of 50 cm of settled snow, over refrozen rain effected layers, which are still moist at ground in places.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Minimize exposure during periods of heavy loading from new snow and wind.

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.
