Regions

Brazeau, Cirrus-Wilson, Icefields.

23-30cm of new snow is expected over the long weekend on the Icefields Parkway. Watch out for wind slabs in exposed alpine terrain and be aware that small, dry loose avalanches are possible in steep, sheltered terrain (talking to you ice climbers!)

Confidence

Moderate

Avalanche Summary

No avalanches observed.

Please consider submitting a MIN to report avalanche activity, conditions, or weather.

Snowpack Summary

20-30cm of snow over the long weekend will create fresh wind slabs. These new wind slabs will sit over a thin and variable snowpack. Nov 10- Treeline snow depths 5-20cm.

Avoid wind loaded pockets in leeward areas and near ridgetop.

Many open crevasses are hidden by thin bridges of wind-blown snow. Roping up, diligent probing, and experience are critical for glacier travel.

Weather Summary

Saturday Snow. Accumulation: 10-20 cm. Wind SW 20 km/h gusting to 50. Freezing level 1600 metres

Sunday Sunny periods and isolated flurries. Trace precipitation. Wind SW 15 km/h gusting 55

Monday Cloudy with scattered flurries. Accumulation: 5 cm. Freezing level: 1800m

Terrain and Travel Advice

  • Avoid freshly wind loaded terrain features.

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.

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.
