In sintesi

Large human triggered persistent slab avalanches continue to be reported.

Triggering is most likely on northerly aspects at upper elevations.

    Triggering slabs will be most likely on wind affected slopes at upper elevations.

    Strong solar radiation may trigger small wet loose avalanches.

    Keep in mind that small avalanches in motion may step-down to deeper weak layers.

Avalanche Summary

On Saturday, a sledder triggered size 2 persistent slab avalanche was reported below an alpine ridgetop near the Clemina Creek. See MIN

Numerous naturally triggered wet loose avalanches up to size 2 were also reported.

NOTE: Observations in this region are currently very limited.

Snowpack Summary

Recent convective snowfall has been highly variable, accumulating over a crust in most areas except shady aspects in the high alpine where soft or wind affected dry snow may be found.

The primary weak layer of concern is a surface hoar, facet, and crust layer from early March, buried 50 to 100 cm deep. While its distribution and sensitivity remain uncertain, it has been highly reactive in the neighbouring Monashee regions.

The lower snowpack is likely strong and bonded in most areas.

Terrain and Travel Advice

  • In times of uncertainty, conservative terrain choices are our best defense.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Cornice failures could trigger large and destructive avalanches.
  • Loose avalanches may step down to deeper layers, resulting in larger avalanches.
