Regions

Lake Louise.

Early season conditions are present with a thin snowpack, lots of variability in snow depth, and plenty of lurking hazards to hit. Some good travel and turns can be found, but options are limited. Travel with care.

Confidence

Low

Avalanche Summary

A few small wind slabs up to size 2 were reported by the local ski hills during avalanche control with explosives. No new natural avalanches were observed.

Snowpack Summary

Residual small wind slabs may remain in the alpine on multiple aspects due to the variable winds earlier in the week. 50-80 cm of total snow at treeline throughout the region, with up to 120 cm in loaded alpine features. Below treeline is generally below the threshold for avalanches.

Weather Summary

Clear weather continues as the arctic ridge of high pressure dominates the region. Winds will remain light from the SW. Temperatures warm to -5 to -10 C depending on elevation as we approach the weekend.

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.
