    Wind slabs are likely to exist on a variety of aspects. Wind slabs could fail on a deeply buried crust layer, initiating a surprisingly large avalanche. Rider triggering is possible.

Confidence

Fair - Due to the number of field observations

Weather Forecast

A weak system will spread light snowfall and moderate southwest winds to the region on Tuesday. On Wednesday expect a mix of sun and cloud and light ridgetop winds. By late Thursday a more intense frontal system should impact the region bringing steady snowfall. Freezing levels should hover around 500m for the forecast period.

Avalanche Summary

No new avalanches have been observed.

Snowpack Summary

Recent heavy rain affected southern parts of the region up to alpine elevations, while the far north remained drier and sports a weaker snowpack in general. Areas which previously received rain have probably now formed a hard frozen crust. High alpine and far northern areas are likely to have wind slabs and large fragile cornices. Deeper in the snowpack, weaknesses such as the mid-November crust-facet layer are still of concern to some operators.
