Small wind slabs may linger on northerly aspects in isolated locations below alpine ridgetops.

Confidence

Moderate

Avalanche Summary

On Monday, several skier triggered size 1 wind slabs were reported on northerly aspects below ridgetops.

Several skier triggered wet loose avalanches up to size 1.5 were reported on sunny aspects.

NOTE: Observations are currently very limited in this region.

Snowpack Summary

Up to 25 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes where buried weak layers may still be present.

Weather Summary

Tuesday Night

Clear skies. 5 to 10 km/h northwest ridgetop wind. Treeline temperature -5 °C. Freezing level valley bottom.

Wednesday

Sunny. 5 to 10 km/h northwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2300 m.

Thursday

Sunny. 10 to 20 km/h southeast ridgetop wind. Treeline temperature 5 °C. Freezing level 2600 m.

Friday

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
