Kernpunkte

The arctic air will clear out and temps will rise but winds will rise as well so we can look forward to new soft slabs forming along ridge tops - there is still some loose dry snow available for wind transport.

The arctic ridge is weakening and warmer air will begin to push in from the west.  A few cm on new snow each day until Friday but no appreciable accumulations.

Avalanche Summary

No new avalanche activity observed on Tuesday.

Snowpack Summary

Snow survey flight today with 4 profiles completed....heavily faceted snowpack in areas below treeline with Nov crust still evident in some locations.  A mix of hard windslab from last weeks winds and thin softslabs from the storm snow later in the week.  The Jan 6 interface still showing up in compression tests in the hard range down 30-40+cm.  Old surface hoar found on this interface at a sheltered location at 2200m near the divide.
