Kootenay Boundary

Storm slabs remain reactive to human triggers, especially in wind affected terrain.

Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Moderate

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

On Wednesday, numerous explosive triggered storm slab avalanches up to size 2 were reported at all elevations on a variety of aspects.

20 to 30 cm of recent snow and strong southwest winds have formed slabs overlying a thick crust.

Below the crust, the snowpack is likely moist to the ground.

• Make conservative terrain choices and avoid overhead hazard.
• Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
• Use small, low consequence slopes to test the bond of the new snow.
• Closely monitor how the new snow is bonding to the crust.
