Avalanche Summary

The following was observed:1.  One natural size 2.5 slab in the Commonwealth area2.  One size 2.5 slab in the Goat Range3.  Several loose dry avalanches up to size 2

Snowpack Summary

25-40cm of snow has fallen since Friday.  In the tree elevations, this storm snow is laying on top of a weaker snowpack.  Some soft slab development has occurred in the alpine but is isolated for the time being.  If the winds pick up and start to move the snow around, the wind slabs will develop and the hazard will increase in the alpine and open areas.
