Avalanche Forecast

No avalanches were reported on Wednesday. However, observations in this region are currently very limited.

Observations are limited at this time of year, please consider sharing any information or photos you have on the Mountain Information Network to help guide our forecasts.

In the alpine, 20-30 cm of recent snow and moderate south wind formed wind slabs in isolated lee features. A robust crust exists on all aspects up to approximately 1400 m and to ridgetop on south aspects.

Cornices are large and loom over slopes below like gargoyles.

A weak layer of surface hoar/crust/facets buried in early January is now around 100 cm down in most areas. Operators continue to monitor this layer. A significant warming event or a large trigger (like a falling cornice) are the most likely things to activate this layer.

• Carefully evaluate steep lines for wind slabs.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Cornice failure may trigger large avalanches.
