Kernpunkte

Conservative terrain choices are key as storm slabs continue to build through the region.

Expect touchier conditions in sheltered areas where a layer of surface hoar can be found.

    New storm slabs are expected to be reactive due to the large surface hoar they’ll form over.
    The storm slab will be most reactive in sheltered areas where surface hoar is buried

Confidence

Low

  • We are uncertain about how the snowpack will react to the forecast weather.
  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

Numerous large wet slab avalanches were reported on Friday in alpine terrain.

If you are getting out, please share observations like avalanches, weather, and riding conditions to the Mountain Information Network.

Snowpack Summary

Up to 45 cm of wind affected new snow sits over a widespread crust at treeline. With warm temperatures throughout the storm, this likely fell as rain as high as 1400 m in some areas of the region.

This new snow was accompanied by moderate to strong southwest winds, meaning that the crust has remained near the surface on southerly aspects while deeper deposits will be found on north and east aspects.

A layer of large surface hoar on the crust will make the storm slab more reactive in sheltered treeline and below treeline locations above 1400 m. Remote triggering is possible in these areas.

The mid and lower snowpack is well settled.

Weather Summary

Saturday Night
Mostly cloudy. 2 to 3 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing Level 1600 m.

Sunday
Mostly cloudy. 3 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Monday
Mostly cloudy. 2 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday
Mostly cloudy. 3 to 5 mm of rain or snow at treeline. 60 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
