Regions

Little Yoho.

Despite the green brick, we have lingering concerns for persistent slabs in this area, where the snow is deeper, and a 20-40 cm slab may overlie the Jan 24 layer. The presence of a cohesive slab is the key part of this Problem, as the weak layer exists in many places, but the slab does not. It's the combination of both that makes the Problem.

Confidence

Avalanche Summary

No new avalanches observed or reported.

Snowpack Summary

Up to 15 cm of recent snow has been blown into windslabs in alpine areas, but provides soft powder at treeline and below. Under this new snow lies a variety of crusts on solar aspects; dry snow on north aspects, and surface hoar/crust (Jan 24) down 15-30 cm around the treeline. Below this interface, the snowpack is generally strong and well settled.

Weather Summary

While the storm track continues to pound the north coast of BC, a ridge of high pressure mainly dominates the interior and the Rockies. A few residual cm of snow are expected overnight Tuesday, followed by a dry week ahead. Temperatures will be cool: -5 to -10, with light to moderate winds out of the southwest.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.

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.

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.
