    The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Confidence

Moderate

Avalanche Summary

Only isolated size one wind slabs near ridge top have been observed in the last few days.

If you're out in the hills, don't forget to post to the MIN. Every bit of information helps.
