After today's wind, it is safe to say we now have a widespread windslab concern. Most alpine areas saw enough wind to form "triggerable" windslabs.

Snowpack Summary
Low down, the settlement from the past few warm days is quite noticeable. Unfortunately, the faceting in the mid to lower pack is still obvious. In many places, the snow has that distinct "upside down" feel to it. The exposed surface hoar has begun to break down with the warmth. At treeline the winds have created widespread windslabs that are sitting on either weak facets, or in some isolated areas, the preserved surface hoar from Dec 15. The alpine now has windslabs on N-S aspects from today's moderate westerly winds. So far no layers have woken up, but during our field day today we had the feeling that the snowpack is changing for the worse.
