Regions

North Rockies, East Kakwa, Tumbler.

Rising freezing levels with clear, sunny skies may create a wet loose problem anywhere in direct sun. Small reactive wind slabs could be found at upper elevations.

Confidence

Low

  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to the timing or intensity of warming will affect the snowpack.

Avalanche Summary

No new avalanches have been reported in the past week.

There are few observations from this region. If you are getting out, please share observations like weather and riding conditions to the Mountain Information Network.

Snowpack Summary

Rising freezing levels will promote moist or wet snow surfaces on most aspects to mountain top. You may be able to find small wind-affected pockets of dry snow on high north facing slopes in the alpine.

At treeline and below, a prominent crust buried late January sits 15 to 30 cm beneath the moist surface snow.

The mid-December facet/crust layer is buried approximately 80 cm deep.

The average snowpack depth at treeline is 90 to 140 cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
