Regions

Glacier.

A persistent weak layer of surface hoar remains a concern at tree line and below. Conservative terrain choice is required as there is a high degree of uncertainty surrounding the distribution and reactivity of this layer.

Confidence

Low

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

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

Human triggering continues on the late January persistent weak layer. Avalanches have been more prevalent below treeline(MIN) and in unsupported terrain. See the MIN in Connaught creek on Tues of a rider remote avalanche, size 1.5.

Snowpack Summary

New snow on Saturday will sit over a crust in most areas leading to small, dry loose avalanches.

Approximately 40cm beneath the surface is the late Jan weak layer 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

Cooling trend starting Friday night with snow forecast on the weekend.

Tonight: Mainly cloudy. Alp low -3°C. Wind SW 30-45 km/h. (FZL) 1000m.

Sat: Flurries, 5-10 cm. High -3°C. Wind SW 30-40 km/h. FZL 1600m.

Sun: Cloudy w/flurries, 5 cm. High -5°C. Wind SW 20 gusting to 45km/h. FZL 1600m.

Mon: Mainly cloudy. No precipitation. Light wind. FZL 1300m.

Terrain and Travel Advice

  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.

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.

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.
