Kootenay Boundary

Travel with caution around steep wind-affected slopes.

No recent human-triggered avalanches have been reported, but a few size 1 to 2 slab avalanches were triggered by explosives earlier this week, mainly on south and southwest aspects. The storm snow should now be well-bonded, except in areas recently affected by wind loading.

Last week's 40 to 70 cm of snow remains soft in sheltered areas but may have formed reactive slabs in wind-affected terrain, particularly near ridgelines.

The snowpack is generally strong, with small surface hoar 50 to 70 cm deep and melt-freeze crusts near the ground, though no recent avalanches have been reported on these layers.

Treeline snow depths are around 100 to 150 cm.

Thursday Night

Cloudy. 15 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Friday

Saturday

Mix of sun and cloud with 0 to 1 cm of snow. 15 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Sunday

Mostly cloudy with 0 to 2 cm of snow. 25 km/h southwest ridgetop wind. Treeline temperature -4 °C.

• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
