Avalanche Summary
A size 1 wind slab avalanche was remotely triggered by a skier on Tuesday in the Seaton area. The skier was skiing a low-angle slope, while an adjacent wind-loaded, steep roll released. This occurred in north-facing, alpine terrain.
Snowpack Summary
Approximately 10 to 15 cm of new snow has buried a widespread crust. Strong winds have scoured surfaces down to the crust in most windward-facing terrain while forming deeper deposits of snow in lee terrain.
Currently, no significant concerns exist deeper in the snowpack.
