Confidence

Moderate

Avalanche Summary

A large glide slab released naturally on Monday. These natural hazards should be given a wide berth.

Wet and dry loose avalanches continue to be triggered by skiers in the region. These avalanches have occurred in steep terrain on a variety of aspects and elevations.

Snowpack Summary

By mid day on Thursday up to 20 cm of new snow could have accumulated with moderate southwest wind. This new snow will overlie a crust on all aspects and elevations. Below these crusts, the upper snowpack is moist.

The mid and lower snowpack is well settled.

Weather Summary

Wednesday Night

Cloudy with 0 to 10 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Thursday

Cloudy with 5 cm of snow. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -5 °C.

Friday

Sunny. 10 to 20 km/h northwest ridgetop wind . Freezing level rising to 2100 m.

Saturday

Sunny. 20 to 40 km/h west ridgetop wind. Freezing level rising to 2400 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Make observations and continually assess conditions as you travel.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
