Points saillants

There is uncertainty on how prolonged warming and sun will impact the snowpack on Wednesday.

Don't let good weather lure you into dangerous terrain.

    Warm temperatures and sun will further destabilize large cornices.

  • Loose Wet

    Prolonged warming and sun may continue to produce wet loose avalanches from steep terrain.

  • Storm Slabs

    Probabilité
    Possible - Likely
    Taille
    1–2

    Recent snow and southwesterly winds have built storm slabs at upper elevations. Slabs may be more reactive where a buried surface hoar layer is present.

Confidence

Moderate

  • Uncertainty is due to how the snowpack will react to the forecast weather.

Avalanche Summary

On Monday, stormy conditions and rising temperatures produced several natural and skier-triggered storm and wind slabs (size 1-2) from alpine terrain.

On Tuesday, natural storm slabs up to size 2 were observed from alpine and treeline terrain. Explosive control in the Fernie area produced storm slabs up to size 2 from alpine terrain.

Looking forward to Wednesday, warm temperatures and sun may continue to destabilize an already weak snowpack.

Snowpack Summary

The surface snow is moist or crusty in many areas due to recent rain and warm temperatures. Up to 25 cm of recent storm overlies stiff, wind-affected surfaces.

A weak layer of surface hoar can be found in some sheltered terrain features buried 40 to 60 cm. In other areas, a melt-freeze crust can be found at similar burial depths, up to around 2000 m.

The remaining snowpack currently has no layers of concern.

Weather Summary

Tuesday Night
Mostly cloudy. 40 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level 3400 m.

Wednesday
Mix of sun and clouds. 50 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level 3500 m.

Thursday
Mostly sunny. 50 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Friday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 300 m.

Terrain and Travel Advice

  • Uncertainty is best managed through conservative terrain choices.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Keep in mind that the high density of wet avalanches can make them destructive.
