Regions

Sugarbowl, Kakwa, McGregor, Pine Pass.

Dangerous avalanche conditions persist with more snow, wind, and warming temperatures expected on Saturday.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Wind slabs have been reactive in recent days, at all elevations. There have been several reports of natural and skier-triggered size 1-2 wind slabs on NE-NW aspects.

With continued snow, wind, and warming temperatures, we anticipate natural and rider-triggered avalanche activity to continue.

Snowpack Summary

Variable amounts of snow continue to accumulate across the region. At higher elevations and exposed terrain, strong winds are redistributing the new snow into deeper deposits on leeward and cross-loaded slopes. Below 1400 m, surfaces will become wet as the rain line creeps higher.

A crust formed in February exists at variable depths, generally 50 to 120 cm below the surface. In isolated, wind-sheltered areas, weak surface hoar may be present atop this crust.

The remainder of the snowpack is consolidated with no other significant layers of concern.

Weather Summary

Friday Night
Cloudy. 2 to 10 mm of precipitation as snow or rain at treeline. 80 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Saturday
Cloudy. 5 to 10 mm of precipitation as snow or rain at treeline. 70 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

Sunday
Mostly cloudy. 3 to 10 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -5 °C.

Monday
Mix of sun and clouds. 2 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • It's a good day to make conservative terrain choices.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
  • Be aware of the potential for large avalanches due to buried weak layers.

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.
