Regions

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

North wind on Sunday may "reverse-load" alpine slopes and form fresh wind slabs.

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Confidence

High

Avalanche Summary

No new avalanches were reported in this region on Saturday.

Snowpack Summary

North wind may "reverse-load" alpine slopes and form fresh wind slabs.

Above 1800 m, 10 - 20 cm of recent snow sits on a supportive crust.

Below 1800 m, recent snow amounts taper quickly and the crust increases in thickness.

Below treeline travel is currently very challenging.

Weather Summary

Sunday night

Partly cloudy, east wind 20 km/h, treeline temperature -7 C.

Monday

Mix of sun and cloud, east wind 20 km/h, treeline temperature -6 C.

Tuesday

Sunny, west wind 20 km/h, treeline temperature -4 C.

Wednesday

Mostly cloudy with 0 - 5 cm snow, west wind 20 km/h, treeline temperature -7 C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.

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.
