We appreciate all your observations on the Mountain Information Network.
Snowpack Summary
We are in the midst of a strong storm that will impact the region for the coming days. We are expecting around 20 to 30 cm of snow to accumulate at White Pass by sunset on Friday, with extreme southwest wind. Wind slabs will likely rapidly form in wind-exposed terrain and storm slabs in sheltered terrain.
The remainder of the snowpack is hard but heavily faceted.
Terrain and Travel
- Good day to make conservative terrain choices.
- Wind slabs are most reactive during their formation.
- Watch for fresh storm slabs building throughout the day.
Avalanche Problems
Wind Slabs
Extreme wind and new snow will rapidly form wind slabs in lee terrain features. Storm slabs may also form in areas sheltered from the wind.
Aspects: North, North East, East, South East, West, North West.
