Regions

Little Yoho.

Ski quality varies from awful in wind-exposed areas to decent in sheltered spots. Be cautious of lingering wind slabs and continued facetting of the surface snow, which may sluff easily in extreme terrain.

Confidence

High

Avalanche Summary

No new avalanches were reported in Little Yoho. In the adjacent Banff region, some small wind slabs (up to size 1.5) were reported with explosives at the Sunshine ski area, and some very small, loose, dry avalanches in extreme terrain triggered by the sun.

Snowpack Summary

25-30cm of settled snow from last week has been redistributed by the wind in exposed locations, burying the Jan 30 weak layer, and in isolated locations formed now what are aging wind slabs. Specific areas exposed to the wind may have strastrugi. The mid and lower snowpack is well settled, with tree-line snow depths ranging from 120 cm to 180 cm.

Weather Summary

Sunday: 2-4 cm of snow, light SE winds and treeline temperatures around -15C. No significant snow in the forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are isolated, but may remain reactive.
  • Closely monitor how the new snow is bonding to the old surface.

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.
