Regions: Badshot-Battle, Central Selkirk, Clearwater, Goat, Gold, Jordan, North Columbia, North Monashee, North Okanagan, North Selkirk, Shuswap, South Columbia, Whatshan.

Storm snow and wind have built fresh slabs at higher elevations. Use caution in wind-affected terrain where deeper deposits exist and human-triggered avalanches are possible.

Confidence

Moderate

Avalanche Summary

On Tuesday, explosives control in the region produced storm slab results up to size 2.5. Several size 2 natural avalanches were observed in steep northerly terrain.

On Monday, a few loose wet avalanches were reported in steep alpine terrain, size 1-2.

Snowpack Summary

10 to 30 cm of storm snow covers the surface at higher elevations. The new snow sits above a crust or moist snow except on high northerly aspects above 2200 m where snow remained dry.100 to 50 cm down is a layer of weak faceted grains above a crust, formed in early February. This layer has generally been gaining strength, however it is still occasionally producing large avalanches at upper elevations where supportive crusts have not formed above it.

Weather Summary

Tuesday Night

Partly cloudy with 0 to 3 cm of snow at upper elevations. Ridgetop wind northwest 15 to 30 km/h. Treeline temperature -5 °C. Freezing level 1200 m.

Wednesday

Mix of sun and cloud. Ridgetop wind southwest 10 to 20 km/h. Treeline temperature +1 °C. Freezing level 2000 m.

Thursday

Mainly cloudy with 1 to 5 cm of snow at upper elevations. Ridgetop wind west 20 to 40 km/h. Treeline temperature 0 °C. Freezing level 1800 m.

Friday

A mix of sun and cloud with 0 to 3 cm of snow at upper elevations. Ridgetop wind southwest 10 to 20 km/h. Treeline temperature +3 °C. Freezing level 2100 m.

Terrain and Travel Advice

  • Brief periods of sun could quickly initiate natural avalanche activity.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.

Avalanche Problems

Storm Slabs

+20 cm of new snow and wind have built fresh slabs at higher elevations. The deepest deposits can be found in north and east facing lee terrain features. Evaluate wind-affected areas carefully, human-triggered avalanches are possible.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
