Expect fresh wind slabs in the alpine. Areas of main concern are gully features and steep lee slopes. Ice climbers should pay attention to local wind conditions. Up-to-date weather station observations can be obtained from Avalanche Canada's website.

Avalanche Summary

Minimal information is available right now, but we expect small windslabs isolated to leeward slopes and gully features (i.e., ice climbs) where the snow has accumulated.

Snowpack Summary

Last weekend's storm produced 25-30 cm of new snow along the continental divide. Settled snowpack depths are now around 40-60 cm at treeline. Recent strong SW winds and the forecasted snow and wind on Friday will contribute to wind slab formation in lee alpine areas and cross-loaded features.

Weather Summary

Overnight Friday, expect upto 10 cm with strong westerly winds during the day. Saturday will be sunny and clear with arrival of a high pressure system.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind-loaded snow.

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.
