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

Moderate

Avalanche Summary

Lake Louise snow safety reported 10 m shooting cracks from skis on Northerly aspects where surface hoar has been thinly buried by drifted snow. Otherwise no new reports of avalanches from the MIN, a patrol up to Bow Summit, or from the ski hills.

Snowpack Summary

Thin stubborn wind slabs on underlying surface hoar were found in the Louise region today. The more widespread wind slab problem described earlier this week has become unreactive. 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. Winds will remain light from the SW-NW. Daytime temperatures warm to 0°C to -5°C depending on elevation. No snow in the forecast.

Terrain and Travel Advice

Approach lee and cross-loaded slopes with caution.

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.
