Points saillants

Avoid steep north-facing slopes, where triggering persistent weak layers is most likely.

Slopes sheltered from the wind will have the best and safest riding.

    If triggered, wind slab avalanches may step down to deeper layers, resulting in very large avalanches.

Avalanche Summary

Over the weekend, numerous natural and human-triggered avalanches, up to size 3, occurred on all elevations and aspects, many failing on the late January persistent weak layer.

No new avalanches have been reported since.

On Saturday, a skier remotely triggered a size 3 persistent. See MIN for photos and details.

Snowpack Summary

10 to 15 cm of new snow sits on a melt-freeze crust that extends to ridge tops on all aspects, except northerly slopes above 1700 m, where surfaces remained dry through the warm-up.

A weak layer formed in February, consisting of facets, surface hoar, or a crust, is found 30 to 60 cm deep. Additional weak layers formed in January are present within the upper 100 cm of snow, including faceted snow, crusts on south-facing slopes, and surface hoar in shaded terrain.

The mid and lower snowpack is generally well-settled and strong.

Terrain and Travel Advice

  • Be mindful that deep instabilities are still present in the snowpack.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Uncertainty is best managed through conservative terrain choices.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
