Avalanche Summary

No significant avalanches were reported in the past couple days.

Snowpack Summary

Up to 15 cm of new snow sits over a crust on solar aspects and all aspects below 1500 m. On high north facing terrain this new snow sits over facets and surface hoar. If the wind picks up new wind slabs are likely to form.

Check out this MIN from our field team.

The mid-snowpack is generally strong but the lower snowpack is a different story..The November facets are still prominent at the base of the snowpack. They are showing signs of improving but this layer remains a significant concern in rocky, shallow, or thin to thick snowpack areas at treeline and above.

Weather Summary

Saturday Night

Mostly clear skies with the possibility of flurries bringing a few cm of new snow. Light westerly winds and a low of -11°C at 1800 m.

Sunday

A mix of sun and cloud with the possibility of convective flurries bringing up to 5 cm of new snow. Light northwest winds and a high of -2°C at 1800 m.

Monday

Mostly clear with no new snow expected. Light northwest winds and a high of -4°C at 1800 m.

Tuesday

Clear skies with no new snow expected. Light northwest winds and a high of -2°C at 1800 m.

Terrain and Travel Advice

  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
  • In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
  • Minimize your exposure time below cornices.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Problems

Deep Persistent Slabs

Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
