Regions

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

Winds will pick up again Wednesday, and then increase further with new snow arriving on Thursday and Friday.

Early season hazards are also still a significant concern out there, as coverage is very thin in many areas.

Confidence

Moderate

Avalanche Summary

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

Snowpack Summary

Moderate to strong westerly winds have redistributed snow in open areas at tree line and above. In sheltered areas 30 cm of soft facetted snow overlies a supportive snowpack to ground. A 2cm thick crust is present halfway down the snowpack but has only been observed at tree line elevations.

Terrain and Travel Advice

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

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.
