Regions
Banff Yoho Kootenay.
Watch for wind slabs in exposed terrain on high alpine slopes, especially where they may overly facets. Two storms have formed most of the current snowpack, and it is a very supportive snowpack considering it is only November. Great ski conditions!
Weather Forecast
Sunday is expected to be moderately cool with a few flurries. 10 cm of snow and swirly winds are expected Monday night.
Snowpack Summary
80-100cm of supportive snow can be expected at treeline. Above treeline there is extensive wind slab development. The wind slabsĀ are a concern in thin snow pack areas or where underlain by weak facets. T
Avalanche Summary
No new avalanche observations.
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.
