Regions

Glacier.

Frosty flurries feature foremost in the forecast.

Temps will rise slightly with the arrival of the new snow, but remain frigid enough to freeze your footsies.

Bring plenty of warm clothing, food, and hot drinks to prevent hypothermia if an emergency arises.

Confidence

High

Avalanche Summary

Natural activity during the cold snap has been limited to loose/dry and wind slabs in Rogers Pass.

Bruins Ridge saw a sz 2 wind slab fail on a SW aspect, most likely on the underlying suncrust.

Several thin sz 1.5 hard slabs were observed off the S side of Christiana Ridge, as well as a sz 2 off the steep SE aspect of Fidelity Mtn.

All noted avalanches failed on a suncrust.

Snowpack Summary

Moderate winds (S/SW switching to N/NE) have redistributed 40-50cms of snow into variable soft to hard surface slabs. These sit upon a sun crust on solar aspects, firm wind effect in the alpine, and soft facetted snow on sheltered N aspects.

Below 2100m there is a crust down 70-80cm (from Dec 5th/6th).

The Dec 1 surface hoar layer is down 90-120cm and is decomposing. However, it is still reactive in isolated snowpack tests.

Weather Summary

Slightly milder temps, flurries, and light winds for the next few days.

Tonight: Increasing cloud, Alp low -16°C, light SW wind.

Tues: Flurries (5-10cm), Alp high -12°C, light ridge wind.

Wed: Flurries (10cm), Alp high -12°C, light E wind.

Thurs: mix of sun/cloud/flurries, trace snow, Alp high -13°C, light E wind.

Terrain and Travel Advice

  • Wind slabs may be poorly bonded to the underlying crust.

Problems

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.
