Avoid lee areas where wind slabs are deeper and more dangerous.

Test small features before committing to large terrain.

• Uncertainty is due to the limited number of field observations.

On Wednesday, there was a report of a large storm slab (size 2) that released naturally from below a rock feature near the Coquihalla. It occurred on a south aspect at treeline.

On Tuesday, there were small to large (size 1-2) storm slab avalanches reported near the Coquihalla and Sasquatch Mountain Resort. Failing 10 to 40 cm deep.

Another 15 cm brings storm totals up to 40 to 70 cm of recent snow, which overlies a crust on south-facing slopes.

The mid-December crust is 150 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.

In general, the snowpack is well settled and right-side up.

• Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
• Be careful as you transition into wind-affected terrain.
• Wind slabs are most reactive during their formation.
• Make observations and continually assess conditions as you travel.
