Regions

South Okanagan, Shuswap, North Okanagan.

Snow and wind continue, which means elevated avalanche hazard. Be especially cautious in areas where the wind may have made deeper deposits of snow.

Confidence

Moderate

Avalanche Summary

Small human triggered avalanches of the new snow over the old surface are being reported in the alpine and at treeline on all aspects over the past two days.

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

Snowpack Summary

30 cm of new snow continues to accumulate atop a thin crust on sun-exposed slopes and surface hoar in wind-sheltered areas.

Beneath, the upper snowpack is largely faceted.

The mid and lower snowpack is generally settled and strong.

Weather Summary

Terrain and Travel Advice

  • 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.
