Avalanche Summary

No new avalanches have been reported since Thursday.

Looking forward, we expect naturally triggered slab avalanches will be unlikely, but human triggering of wind slabs may remain possible.

Snowpack Summary

Wind-affected snow and wind slabs formed by shifting wind may be found on various aspects at upper elevations. Over a meter of old storm snow is gradually settling, staying dry and powdery in the cold. In some areas, one or two thin rain crusts lie buried 40 to 90 cm deep.

A weak layer from late January, composed mainly of a hard, slippery crust or a mix of faceted grains and surface hoar on shady upper-elevation slopes, is now buried 100 to 130 cm below the surface.

The mid and lower snowpack is well-settled with no major concerns.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

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.
