Regions

Jasper, Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Maligne, Marmot, Miette Lake, Pyramid.

Winter has returned with a week of colder temperatures.

Winds from all directions have built fresh wind slabs in unexpected areas. Stay alert to newly formed slabs and choose sheltered terrain for better riding conditions.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Reports of natural size 1 wind slabs in the last 48 hours.

Snowpack Summary

Up to 30cm of soft snow can be found in sheltered locations sitting on various melt freeze crusts and older wind affected snow, or a patchy surface hoar layer below treeline. The midpack is generally dense and well consolidated with basal facets in many areas.

Weather Summary

Colder air remains in place with alpine temperatures generally around -15 to -20°C, and valley temperatures staying well below freezing. Northerly winds will slowly switch to a more westerly flow this week. Precipitation looks light and intermittent, with only small amounts expected.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.

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.
