Riders may still trigger wind slabs in the alpine.

Assess conditions as you go, and consider terrain traps below you before committing to your line.

Confidence

Moderate

Avalanche Summary

On Monday, a few naturally triggered storm slabs and wet loose avalanches up to size 1.5 were reported in the alpine near Fernie.

NOTE: Observations are currently very limited.

Snowpack Summary

Up to 30 cm of recent snow in localized areas and strong variable wind may have formed wind slabs on lee slopes at upper elevations. However, triggering these slabs will become unlikely on sunny slopes that have a sun crust.

This snow overlies a robust crust everywhere except northerly aspects at upper elevations, where old snow may have remained dry.

The mid/lower snowpack is well settled and strong.

Lower elevations are melting out rapidly.

Weather Summary

Wednesday Night

Partly cloudy. 10 to 20 km/h east ridgetop wind. Treeline temperature -1 °C. Freezing level 2000 m.

Thursday

Mix of sun and clouds. 20 to 30 km/h east ridgetop wind. Treeline temperature 3 °C. Freezing level 2300 m.

Friday

Sunny. 20 km/h east ridgetop wind. Treeline temperature 4 °C. Freezing level 2700 m.

Saturday

Mix of sun and cloud. 10 km/h northeast ridgetop wind. Treeline temperature 6 °C. Freezing level 3000 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Avoid sun-exposed slopes, especially if the snow surface is moist or wet.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

Avalanche Problems

Wind Slabs

Small wind slabs may linger on northerly aspects in isolated locations below alpine ridgetops.

Aspects: North, North East, North West.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
