Regions

East Kakwa, Tumbler.

Pockets of wind-deposited snow may sit atop a generally weak, facetted lower snowpack.

Confidence

Low

Avalanche Summary

No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The snowpack is generally shallow with sugary facetted crystals, and significant wind effect. Slopes at higher elevations have been extensively stripped to the ground or melt-freeze crusts by the wind, while pockets of deeper, wind-loaded snow may be found around ridges or in gully features.

Average snowpack depths at treeline are roughly 20 to 70 cm. Many hazards are on or just below the surface.

Sunday

Mix of sun and cloud with no precipitation, southwest alpine winds 30 to 50 km/h, treeline temperature -6 °C.

Monday

Mostly sunny with no precipitation, southwest alpine winds 20 to 40 km/h, treeline temperature -5 °C.

Tuesday

Mostly sunny with no precipitation, southwest alpine winds 20 to 30 km/h, treeline temperature -4 °C.

Terrain and Travel Advice

  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.

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.
