Regions

Little Yoho.

Great conditions this week with mostly stable snow and nice weather, a good time for alpine objectives. We have lingering concerns for persistent slabs in this area, where a 20-40 cm slab may overlie the Jan 24 surface hoar/crust layer in random places. As the surface snow becomes deeper, watch for cracking or signs of slab formation.

Confidence

Avalanche Summary

No new avalanches observed or reported.

Snowpack Summary

The snow surface is a mix of crusts and soft snow, and changes often within short distances, but soft powder is on the surface on the north aspects at treeline and sheltered alpine areas. Below this, 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

A ridge of high pressure will keep our region dry for the next few days, temperatures will remain -5 to -10, and winds will be light/moderate from the West. There is hope for a few (<5 cm) on Friday and Saturday - fingers crossed!

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.
