Regions

South Okanagan, Shuswap, North Okanagan.

Hazard may be Moderate in localized areas that receive more than 10 cm of new snow.

Confidence

High

Avalanche Summary

On Sunday, numerous explosive triggered wind slabs up to size 2 were reported on steep slopes below alpine ridgetops.

NOTE: Observations in this region are currently very limited.

Snowpack Summary

Up to 10 cm of snow overlies a 10 to 15 cm crust. Beneath this is a moist upper snowpack.

The mid/lower snowpack is well settled and strong.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
