Avalanche Summary

No new or recent avalanches have been reported, however there are very few field observations coming from this forecast area.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Roughly 5-10 cm of new snow fell in the region in the early week. It added to an existing skiff of snow atop a widespread crust presently found at or near the surface below 1400 m. South facing slopes are generally scoured.

The snowpack is generally shallow and faceted (weak, sugary) with multiple crusts in the mid snowpack. Pockets of deeper, wind-loaded snow may be found near ridges, gully features, and established avalanche paths.

Average snowpack depths at treeline are roughly 20 to 80 cm.

Weather Summary

Tuesday night

Cloudy with lingering flurries and a final trace of new snow. Northeast alpine wind 20-25 km/h.

Wednesday

Becoming mainly sunny or thin overcast. Northeast alpine wind 15-20 km/h. Treeline temperature -29°C.

Thursday

Mainly sunny. Northeast alpine wind 25-30 km/h. Treeline temperature -32°C.

Friday

Sunny. North alpine wind 15-20 km/h. Treeline temperature -36.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.

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.
