Regions

North Columbia, South Columbia, Clearwater, Esplanade, Jordan, North Monashee, North Selkirk, Shuswap, Badshot-Battle, Central Selkirk, Goat, Gold, Retallack, Whatshan.

Riders may still trigger wind slabs in the alpine.

Periods of low danger can be a good time to check out larger objectives.

Confidence

Moderate

Avalanche Summary

On Tuesday, there was a natural wet loose avalanche cycle in the recent snow, mostly small but some up to size 2.

On Monday, several skier-triggered size 1 wind slabs were reported on northerly aspects below ridge tops.

NOTE: Observations are currently very limited.

Snowpack Summary

Up to 25 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes, where buried weak layers may still be present.

Weather Summary

Wednesday Night

Partly cloudy. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Thursday

Sunny. 20 to 30 km/h east ridgetop wind. Treeline temperature 2 °C. Freezing level 2500 m.

Friday

Sunny. 5 to 10 km/h southeast ridgetop wind. Treeline temperature 5 °C. Freezing level 2700 m.

Saturday

A mix of sun and cloud. 5 km/h southeast ridgetop wind. Treeline temperature 6 °C. Freezing level 2700 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
