Keep an eye on conditions that change with elevation and time. Rider triggerable wind slabs could be found in higher elevation terrain. As the snow surface gets moist small wet loose avalanches could be triggered as well.

Avalanche Summary

No new avalanches were reported in the past couple days.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

10cm of dry new snow sits over 45cm of moist previous storm snow. Below this is a thick crust from late December. At lower elevations around 10cm sits over a more recent crust.

The snow surface will likely become moist as the freezing level rises.

Treeline snow depths are roughly 150 to 200 cm.

Terrain and Travel Advice

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Wind Slabs

New snow and southerly winds could form small wind slabs on west, north and east aspects. These wind slabs will likely be found in immediate lee features at treeline and above.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
