    Fresh wind slabs are forming on mainly south to west aspects behind exposed terrain features. Slabs found on south aspect slopes could become more unstable when the sun is out.

Confidence

High - The weather pattern is stable

Avalanche Summary

No new avalanches observed.

Snowpack Summary

Right now, the most important part of the snowpack analysis is figuring out how the wind is redistributing snow into wind slabs. New wind slabs are most likely to be found on south to east aspects behind exposed terrain features, and could be touchy, especially on steep unsupported terrain. The previous metre or so of storm snow has bonded well to the underlying snow. A thin freezing rain crust buried under 10 cm of new snow was reported from the North Shore mountains, but I suspect the only impact this will have will be on skiing quality. Wind slabs aside, the snowpack is otherwise considered to be well settled and stable.
