Regions

Glacier.

Keep the persistent slab problem on your mind at treeline and below.

Isolated natural avalanches were observed in Connaught creek and human triggering remains possible.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Natural persistent slab avalanches up to size 1.5 were observed below treeline on steep unsupported slopes in Connaught creek on Sunday. Field teams also reported multiple wumps at 2100m and below.

A solar triggered, natural cycle was observed earlier this week along the highway corridor with avalanches up to size 3.0

Snowpack Summary

10-20 cm of recent storm snow arrived with moderate to strong wind developing wind slabs in exposed terrain in the alpine and at treeline. Storm snow sits over a crust 20-40 deep most areas at upper elevations.

30-60cm beneath the surface is the late Jan weak layer consisting of surface hoar, facets, and a crust. This layer is widespread with largest surface hoar in sheltered areas at treeline and below.

The mid and lower snowpack is generally well settled and strong.

Weather Summary

Stable weather pattern.

Tonight: Cloudy with clear periods. Alp low -8°C. Wind light to 15 km/h. Freezing level (FZL) 500m.

Mon: Cloudy with sunny periods and isolated flurries. Trace snow. High -8. Wind SW 15-30. FZL 1200m.

Tues: Cloudy with sunny periods and isolated flurries. Trace snow. Wind SW 15-35 km/h. FZL 1200m

Wed: Cloudy with sunny periods. No snow. High -6. Wind light to 15. FZL 1100m.

Terrain and Travel Advice

  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.

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.
