Regions

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

30-40cm of new snow over the weekend has improved ski quality. Give the new snow time to settle. Heightened avalanche conditions exist on specific terrain features which require careful terrain and snow evaluation.

Confidence

Moderate

Avalanche Summary

Sunday's Icefield team noted numerous sun activated loose dry avalanches up to size 1.5. Some running a fair distance. Visibility was good. One size 2 windslab occurred on Snowdome in the alpine. Saturday's field team had very poor visibility and no avalanches were observed. Nov 20th observed a few size 1 human triggered wind slab avalanches in steep alpine morainal terrain.

Snowpack Summary

The Icefields received 20-40cm of new snow this weekend. Travel is supportive and Parkers manual weather station has 109cm height of snow. A 2cm thick crust is at midpack and found up to 2200m elevation. Maligne received 10cm of new snow.

Weather Summary

Monday will bring clouds, sun, flurries, -8 °C, and light West winds. Tuesday to Thursday are expected to be sunny periods, isolated flurries, -14 °C, and light Southwest winds.

Terrain and Travel Advice

Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Expect slab conditions to change drastically as you move into wind-exposed terrain.

Problems

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.

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.
