Regions

Little Yoho.

Watch for lingering alpine wind slabs that can be triggered in steep but skiable terrain.

Avalanche Summary

No new avalanches were observed or recorded over the past 24 hours. However, a few skier-triggered wind slabs were reported yesterday on Emerald Peak.

Snowpack Summary

3-5cm of new snow over the last 24 hours at treeline.

The wind effect exists in the high alpine, but many sheltered areas have soft snow. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 110 to 160 cm.

Weather Summary

30-40kmh NW winds, no snow and -12 to -16C at treeline on Friday.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected 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.
