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

During the day on Friday the snow surface will become moist on all aspects and elevations except for high north facing terrain, where up to 15 cm overlies a crust from late March. Below these crusts, the upper snowpack is moist.

The mid and lower snowpack is generally well settled.

Weather Summary

Thursday Night

Clear skies. 20 to 40 km/h northwest ridgetop wind. Treeline temperature -14 °C.

Friday

Sunny. 10 to 20 km/h northwest ridgetop wind. Freezing level rising to 2000 m.

Saturday

Sunny. 20 to 40 km/h west ridgetop wind. Freezing level rising to 2300 m.

Sunday

Sunny. 20 to 40 km/h west ridgetop wind. Freezing level rising to 2600 m.

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.
  • Avoid sun-exposed slopes, especially if the snow surface is moist or wet.
  • Avoid travelling on slopes below cornices.
  • 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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
