Lo esencial

Reactive wind slabs linger in exposed terrain. While unlikely, small avalanches in motion could step down to much deeper weak layers.

    Westerly winds have formed reactive wind slabs in exposed alpine and treeline terrain.

    A crust with facets deep in the snowpack remains a concern, particularly in areas with a thinner snowpack. While the probability of triggering this layer is low, the consequences could be severe.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Recently, small wind slab avalanches have been observed in very steep, extreme northeast-facing alpine terrain.

Otherwise, no new avalanches have been reported, but observations are extremely limited in the region.

Snowpack Summary

Expect to find wind-affected surfaces in exposed terrain at higher elevations.

Approximately 40 to 80 cm of recent snow continues to settle above a melt-freeze crust that is thin or absent in alpine terrain, while thicker and widespread at treeline and below.

Near the bottom of the snowpack, a series of crusts exists with associated faceted snow.

Weather Summary

Thursday Night
Mostly cloudy. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Friday
Cloudy. Trace amounts of snow. 40 km/h west ridgetop wind. Treeline temperature -6 °C.

Saturday
Cloudy. 2 to 8 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C with a chance of a slight temperature inversion.

Sunday
Mostly cloudy. 5 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -1 °C with a chance of a slight temperature inversion.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
