Points saillants

Stick to conservative terrain and avoid terrain where the snowpack thins.

Warm temperatures may increase the reactivity of buried persistent weak layers.

    Fresh and reactive wind slabs have formed over hard, wind affected surfaces. Recent winds have varied, look for slabs on all aspects.

    A widespread layer of facets sits 70-100 cm deep. In shallower inland areas, depth hoar exists. It is most likely to be triggered in areas where the snowpack transitions from thick to thin or by a wind slab avalanche stepping down.

Confidence

Moderate

  • Uncertainty is due to whether buried persistent weak layers become active, triggering avalanches, with the arrival of the forecast weather.

Avalanche Summary

Reports are limited; however, on Saturday, natural avalanches up to size 3 were observed. Wind slab avalanches are expected to continue as strong winds and snow persist.

On Wednesday, explosive control triggered up to size 3 avalanches in the interior of the region, releasing on multiple layers, including lower snowpack facets.

Snowpack Summary

Alpine terrain remains heavily wind affected, with light snowfall each day redistributed into deeper deposits on north and east facing slopes. South facing slopes remain scoured.

At treeline a small surface hoar layer exists 60-90 cm deep. The lower snowpack consists of 60-100 cm of weak facets, with depth hoar in shallower areas.

Alpine snowpack depths vary widely due to wind effect, ranging from 130-250 cm across the region.

Weather Summary

Monday Night
Mostly cloudy. 4 to 10 cm of snow. 40-60 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 500 m.

Tuesday
Mostly cloudy. 5 to 10 mm of precipitation as snow or rain at treeline. 40-60 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 500 m by end of day.

Wednesday

Mostly cloudy. 30 to 50 cm of snow. 40-60 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level drops to 500 m.

Thursday
Mostly cloudy. 2 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 300 m.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • The likelihood of deep persistent slab avalanches will increase with each day of warm weather.
