Regions

Northwest Coastal, Boundary, Stewart.

Watch for signs of wind loading as you move into more open trees.

Avoid leeward features, where you're still likely to trigger a slab.

Confidence

High

  • Confidence is due to a stable weather pattern with little change expected.

Avalanche Summary

A large avalanche cycle occurred on Tuesday, ending on Wednesday. Numerous large (size 2-3) storm slab avalanches were reported.

No new avalanches have been reported on Thursday or Friday.

Snowpack Summary

70-100 cm of snow fell during the storm earlier in the week. Most areas received snow above 1100 m. Areas exposed to the wind have likely been heavily affected. This new snow fell on a previously wind-affected and faceted layer.

The mid and lower snowpack are well settled.

Treeline snow depths throughout the region range from 250 cm to 350 cm.

Weather Summary

Friday Night
Mostly cloudy. Up to 5 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -11 °C.

Saturday
Mix of sun and clouds. 1 cm of snow. 10 km/h southeast ridgetop wind. Treeline temperature -11 °C.

Sunday
Mostly sunny. 10 km/h south ridgetop wind. Treeline temperature -14 °C.

Monday
Mix of sun and clouds. 5 to 10 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -13 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Carefully evaluate steep lines for wind slabs.

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.
