Snowpack Summary

5-15 cm of new snow falling Wednesday has been redistributed at upper elevations by southwesterly winds. This sits on a melt-freeze crust or wet snow depending on elevation, except for north aspects above 2000 m where it may be sitting on dry snow and/or weak feathery surface hoar. Below 1800 m the entire lower snowpack is either moist or wet.

Avalanche Problems

Wind Slabs

Precipitation falling as snow at uppermost elevations with predominantly southerly winds is expected to develop thin wind slabs in the lee of terrain features.

Be cautious as you transition into wind affected terrain.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
