Regions

Little Yoho, Kootenay.

Wind increasing Sunday night with 15 cm forecast Monday. Current observations and outlook support moderate danger, but more snow or stronger wind than forecast will increase danger to considerable. Users should stay observant to local snow, loading and changing conditions tomorrow.

Confidence

Low

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

A small skier/climber accidental was posted to facebook recently near the Stanley Headwall, likely on the Jan 24 surface hoar on Saturday.

A recent MIN report with small avalanches occurring on Jan 24 surface hoar in the Tumbling Peak area.

Last Sunday an avalanche on Jan 24 surface hoar was triggered in Little Yoho Valley in Yoho Park.

Snowpack Summary

20-30 cm of recent low density snow (15cm more on the way Monday), with minimal wind effect, overlays sun-crusts on solar aspects and scoured terrain in the alpine. The Jan 24 layer (surface hoar/crust) is down 30-40 cm at treeline and has been reactive in some areas in Yoho and Kootenay – Dig down and check for this layer before committing to steep terrain

Weather Summary

A return to seasonal temperatures is expected, with valley temperatures around -2 and ridge temperatures near -10. Up to 15 cm of new snow is forecast Monday, depending on the model, accompanied by strong SW winds. These conditions will build fresh wind slabs.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

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.

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.

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.
