Keep an eye on conditions that change with elevation and time. Wind slab could be encountered at higher elevations, as the freezing level rises wet loose avalanches will increase in size and likelihood.

Avalanche Summary
Several natural loose dry avalanches were reported on Mondayand Tuesday. These avalanches were up to size 1.5 and released in steep terrain.
Please continue to post your observations and photos to the Mountain Information Network.
Snowpack Summary
Ongoing southerly winds have scoured south facing terrain and created wind slab on west, north and east facing terrain features. A new layer of surface hoar exists on or near the surface in sheltered terrain. around 50 to 70cmoverlies a rain crust formed in late December.
The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.
Snowpack depths are roughly 140 to 180 cm at treeline.

Terrain and Travel Advice
- 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.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Wind Slabs
Ongoing southerly winds have formed wind slab on west, north and east aspects. These wind slabs could still be rider triggerable.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
Likelihood
