Snowpack Summary

Surface snow is faceting. Thin windslabs and wind effect in exposed areas from recent outflow winds. 10-20cm of soft snow in sheltered S and W aspects. This sits on top of the Nov crust (up to 2300m) and is supportive to skis. Basal facets showed variable results in tests from sudden results to no results. Overall the snowpack is thin and variable.

Avalanche Summary

Several loose dry avalanches in the alpine from steep terrain on a variety of aspects to up to size 2 (mostly size 1-1.5). One old size 1.5 wind slab observed from the outflow wind event in a cross loaded alpine feature.

Confidence

Wind effect is extremely variable
