In sintesi

Avoid north-facing, alpine slopes where triggering persistent weak layers is most likely.

    This is a low probability, high consequence situation. Choose conservative terrain free from terrain traps.

Avalanche Summary

No new avalanches have been reported since Monday.

On Monday, near Kamloops, a natural size 2 glide slab avalanche was reported on a southwest-facing slope at 1500 m.

On Saturday, a rider triggered size 2, persistent slab avalanche was reported. This avalanche occurred on a west facing slope at 2000 m. See MIN for details.

Snowpack Summary

5 to 10 cm of snow covers a melt-freeze crust. The crust exists on all aspects, except possibly high-elevation north-facing slopes. This overlies 30 to 60 cm of snow that sits above a crust in many areas, or surface hoar/facets in wind-sheltered areas.

A weak layer, buried in late January, consists of surface hoar/facets or a crust is found down 50 to 90 cm. This remains a lingering concern. Below this, the mid and lower snowpack is generally settled and strong.

Terrain and Travel Advice

  • Be mindful that deep instabilities are still present in the snowpack.
  • Keep in mind that human triggering may persist as natural avalanches taper off.
