Regions: North Okanagan, Shuswap, South Okanagan.

Continuously assess conditions and look for signs of instability as you move through terrain.

Wind slabs are most reactive during their formation.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in the past couple of days.

Snowpack Summary

Around 20 cm of new snow has buried a variety of layers including surface hoar in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain. A new crust may be found on sun exposed terrain and all aspects below treeline.

Another layer of surface hoar is down around 30 cm in sheltered areas.

The widespread crust buried in early February is down 40 to 60 cm and has sugary facets on top.

Weather Summary

Saturday Night

Cloudy with up to 5 cm of snow. 35 to 45 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.

Sunday

Cloudy with up to 10 cm of snow. 35 to 55 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1600 m.

Monday

Terrain and Travel Advice

  • Carefully monitor the bond between the new snow and old surface.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be carefull around freshly wind loaded features.

Avalanche Problems

Wind Slabs

Recent new snow has formed wind slabs at higher elevations. Avoid wind loaded areas.

Aspects: North, North East, East, South East, North West.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Persistent Slabs

A crust from early February has produced avalanches in the region. This layer is problematic where facets overlie it.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 2.5
