Kootenay Boundary

Conditions will change with elevation and wind exposure. Reactive slabs remain a concern in wind-loaded features, but sheltered terrain holds great riding conditions.

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 Sunday, loose dry natural avalanches were observed up to size 1.5 from steep terrain features. Explosives triggered slab avalanches to size 1.5.

Moving forward, expect slab reactivity in wind-loaded terrain features, with loose sluffing on steep, sheltered slopes.

Up to 15 cm of new snow is expected by Tuesday morning. This falls over 40-60 cm of wind affected, settling snow that is generally bonding well to the crust below.

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

Monday Night
Cloudy. 5 to 15 cm of snow. Highest amounts are expected in the north, near London Ridge. 50 km/h southwest ridgetop wind. Treeline temperature -6 °C. Freezing level 1200 m.

Tuesday
Mix of sun and clouds. 20 km/h southwest ridgetop wind. Treeline temperature -7 °C. Freezing level 1100 m.

Wednesday
Mostly cloudy. 10 to 40 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 800 m.

Thursday
Mostly cloudy. 3 to 5 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -4 °C.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
• Approach lee and cross-loaded slopes with caution.
