In sintesi

Don't let sunny skies lure you onto large, steep slopes.

Large slab avalanches remain possible to trigger at treeline and above.

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–3

    At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2.5

    30 to 40 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind-affected terrain.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely
    Dimensione
    1–1.5

    Expect natural wet loose avalanches to occur when the sun warms the dry snow for the first time.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

On Friday, a naturally triggered size 2.5 persistent slab was reported near Fernie on a north aspect below a steep headwall in the alpine.

Numerous naturally triggered size 2 storm slabs were also reported on primarily north/east aspects in the alpine.

Snowpack Summary

Cornices are large and looming. Avoid traveling underneath them.

30 to 40 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind-affected terrain.

The recent snow sits on a 1 to 10 cm thick crust on all aspects. The thickness of the crust depends on elevation.

At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.

The mid/lower snowpack is well settled and strong in most areas.

Weather Summary

Saturday Night
Partly cloudy. 0 to 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -13 °C.

Sunday
Sunny. 30 km/h west ridgetop wind. Treeline temperature -12 °C.

Monday
Mostly cloudy. 50 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1800 m.

Tuesday
Mostly cloudy. 2 to 5 mm of rain at treeline. 70 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level rising to 2400 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried surface hoar.
  • Make conservative terrain choices and avoid overhead hazard.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • Cornice failures could trigger large and destructive avalanches.
