Avalanche Summary
On Saturday, the main concern is storm and wind slab avalanches where the precipitation has fallen as snow. At tree line and below expect small loose snow avalanches in steep terrain on all aspects.
Snowpack Summary
Recent snowpack observations have been very limited and confidence is low. The latest series of storms are expected to have brought wet snow to only the uppermost elevations within the region. In these highest elevations there may be as much as 100+cm of new snow accumulation. This more than likely sits on a widespread crust on all aspects and elevations except for north facing terrain in the alpine. At lower elevations, rain has saturated an already wet snowpack.
Problems
Storm Slabs
Continuous precipitation over the past few days combined with wind at upper elevations has built reactive storm slabs.
Be cautious as you transition into wind affected terrain.Minimize exposure during periods of heavy loading from new snow/rain and wind.The new snow will require several days to settle and stabilize.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Loose Wet
Rain at lower elevations will gradually break down surface crusts and contribute to wet snow sluffing and gathering mass in steep terrain.
Use caution above cliffs and terrain traps where small avalanches may have severe consequences.
Aspects: All aspects.
Elevations: Alpine, Treeline.
