20cm of recent snow and moderate Southerly winds have created wind slabs in alpine lee features. These slabs sit on a melt-freeze crust and could be sensitive to human triggering. A surface hoar layer may be buried ~20cm on Northerly alpine terrain.
Use caution in lee areas. Recent wind loading have created wind slabs.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.

Surface melt-freeze crusts are capping weak isothermal snow in thin snowpack areas BTL. These crusts are also prevalent at tree-line and above on solar aspects. Crusts have been breaking down by mid afternoon from the heat of the day.
Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Aspects: South East, South, South West, West, North West.
Elevations: Below Treeline.
