Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Assess steep lines for wind slabs before committing.

Forecast confidence is limited this time of year due to few observations.

Confidence

Moderate

Avalanche Summary

Small natural wind slabs have been reported in the region. Observations are very limited in this region.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

On high north facing terrain up to 10 cm of dry snow may be found.  A new crust will likely be found on all other aspects and elevations. This crust will likely become moist throughout the day with rising temperatures and solar input.

Below treeline terrain is snow free or has very low snow cover. Travel conditions are challenging with exposed rocks, stumps, and open creeks.

Check out this MIN report from Slalok for recent conditions and coverage.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Expect shallow snow cover that barely covers ground roughness.

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.
