Regions

South Okanagan, Shuswap, North Okanagan.

As new snow accumulates and temperatures rise, monitor for signs of instability and assess how it is bonding to underlying surfaces.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

If you head into the backcountry please consider submitting a MIN post.

Snowpack Summary

New snow continues to gradually accumulate atop a thin crust on sun-exposed slopes and surface hoar in wind-sheltered areas. Approximately 30 cm may have accumulated by Saturday afternoon.

Beneath, the upper snowpack is largely faceted.

The mid and lower snowpack is generally settled and strong.

Terrain and Travel Advice

  • Watch for signs of slab formation throughout the day.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Closely monitor how the new snow is bonding to the crust.

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.
