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

Wednesday night

Clearing, still thin overcast. Northeast wind 20-30 km/h, increasing.

Thursday

Mainly sunny or thin overcast. Northeast wind 30-35 km/h. Treeline temperature -32°C.

Friday

Sunny. Northeast or north alpine wind 5-15 km/h. Treeline temperature -32°C to -36°C.

Saturday

Sunny. Variable alpine wind 5-15 km/h. Treeline temperature -30°C to -34°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
