New snow and easterly wind will form fresh, reactive wind slabs.

Observations in this region are limited. If you head out into the backcountry, let us know what you're seeing in a MIN report.

    New snow accompanied by southeast winds on Tuesday will form fresh, reactive slabs throughout the day. Recent winds have varied in direction, so be cautious of wind-loaded pockets on all aspects.

    Cornices are large, looming, and may trigger large persistent slabs on slopes below.

    Persistent weak layers of crusts/facets or surface hoar in the top 200 cm of the snowpack may be possible to trigger where there is not a thick crust under the recent snow.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

On Saturday, a few skier triggered size 1 wind slabs were reported on a variety of aspects at treeline.

Observations in this region are very limited. If you head out into the backcountry, let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Cornices are large and looming. Avoid travelling underneath them.

Up to 15 cm of snow is expected on Tuesday, accompanied by strong southeast winds. This overlies 10 to 20 cm of recent snow and wind slabs at treeline and above, formed by strong southwest winds. Below the recent snow are a variety of surfaces, including small surface hoar, facets, crusts, and wind-scoured snow.

There are multiple persistent weak layers consisting of crust/facets or surface hoar in the top 200 cm of the snowpack.

Weather Summary

Monday Night

Mostly clear skies. 10 km/h south ridgetop wind. Treeline temperature -8 °C.

Tuesday

Mix of sun and clouds. 5 to 15 cm of snow. 30 to 50 km/h east ridgetop wind. Treeline temperature -9 °C.

Wednesday

Mostly cloudy. 5 to 10 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -12 °C.

Thursday

Mix of sun and clouds. 2 to 3 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Cornice failures could trigger large and destructive avalanches.
