Kootenay Boundary

Watch for changing conditions as you shift elevation and aspect - wind affected features may remain reactive to human triggers.

Moderate

• The snowpack structure is generally well understood.
• Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

On Saturday, wind affected features were reactive to rider triggers to size 1 and sluffing was observed in steep, sheltered features. We expect this to continue with light amounts of new snow.

40–60 cm of recent snowfall combined with strong southwest winds has formed slabs over a 2–5 cm thick crust.

The mid and lower snowpack is generally well-settled and contains multiple crust layers.

• Closely monitor how the new snow is bonding to the crust.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Approach lee and cross-loaded slopes with caution.
