Regions

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

Good skiing and riding remains in sheltered areas at and below treeline.

An incoming storm should result in small amounts fresh snow through the weekend, with increasing intensity on Monday. Winds will intensify and build windslabs as the snow falls.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Snowpack Summary

In sheltered areas, roughly 30 cm of soft snow overlies a supportive snowpack all the way to the ground. We’re currently tracking a mid-November melt-freeze crust located in the mid-pack, though it has not shown any activity in our profiles.
Alpine and exposed treeline slopes are showing signs of wind effect, which is mostly just impacting riding quality at this point.

Terrain and Travel Advice

Carefully evaluate steep lines for wind slabs.
Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.

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.
