Avalanche Summary
No new reports of avalanches over the past few days.
On Wednesday our field team observed a size 2 natural wind slab avalanche on a southeast aspect at 1500m.
Snowpack Summary
Recent continuous strong southerly winds combined with new snow created wind slab on all exposed terrain on north aspects. South aspects are a mix of scoured and pressed surfaces. As the wind shifts to the north snow could begin to be redistributed on to south facing slopes.
In shallow snowpack areas a layer of loose facets sits at the bottom of the snowpack.
Terrain and Travel
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Use ridges or ribs to avoid areas of wind loaded snow.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Wind Slabs
Previous southerly winds have formed wind slab on north aspects and cross loaded some east and west. As the wind shifts to the north it is possible that some snow could be redistributed back on to south ffacing slope.
Aspects: All aspects.
Elevations: Alpine, Treeline.
