    New wind slabs will build with the incoming storm.  Carefully evaluate the bond with the new snow and the underlying surface.  The previous windslabs that developed earlier in the week will be hard to see under the new snow so use caution.

Avalanche Summary

No new natural avalanche activity. 

Snowpack Summary

Not much change over the course of the day today.  Melt freeze crusts on solar aspects to the peaks, and widespread temperatures crusts below 1900m.  Most alpine terrain is wind affected with widespread wind slabs and isolated wind slabs at treeline.  The 0211 interface is down 70-100cm at treeline and continues to produce moderate to hard shears that are sudden planar in nature.
