    New slabs may have formed on a few steep, wind-loaded slopes where there was enough snow to cover rocks and rough ground.

Confidence

Moderate

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

Avalanche Summary

Avalanches may be possible in steep alpine features where there’s enough snow to cover rocks and ground roughness.

There have been very few backcountry reports. If you head out, please share observations and photos on the MIN.

Snowpack Summary

We suspect 10 to 30 cm of new snow fell at upper elevations on Tuesday, with strong southwest wind forming some deeper deposits in the alpine. This snow fell on a very thin base: just 20 to 50 cm of rain-soaked snow above 1000 m and bare ground at lower elevations. The shallow snowpack continues to make travel and access challenging across most riding areas.

Cloudy. 15 to 25 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level drops from 1800 to 800 m as storm passes.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
