Regions

Glacier.

Persistent slab are becoming less reactive but the consequence of triggering this layer remains very high.

Conservative terrain choice is the best way to manage the uncertainty surrounding this problem.

Confidence

Moderate

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

Avalanche Summary

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

Natural avalanche activity has slowed, but human triggering of the January persistent weak layer is still possible. See the MIN in Connaught creek on Tues of a size 1.5 rider remote avalanche, or the aptly titled MIN report of whumping near video peak in Connaught creek from Friday.

Snowpack Summary

New snow on Saturday night will sit over a crust in most areas leading to small, dry loose avalanches in protected areas with wind slabs developing in exposed terrain.

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 (up to 40mm) in sheltered areas at treeline and below.

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

Weather Summary

Gusts of strong wind overnight with light snow.

Tonight: Flurries, 10cm. Alp low -5°C. Wind SW 30 gusting to 55 km/h. Freezing level (FZL) 1300m.

Sun: Mainly cloudy with sunny periods, isolated flurries. Trace snow. High -5. Light SW wind gusting to 30. FZL 1600m.

Mon Mainly cloudy, isolated flurries. Trace snow. High -7. Wind SW 20-35. FZL 1600m.

Tues Cloudy, scattered flurries, 5 cm. Wind SW 15 gusting 40. FZL 1300m

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.

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.
