Keep an eye on changing conditions during the day

Light snowfall and moderate southeast wind will likely form small wind slabs by the afternoon

High

Avalanche Summary

No avalanches have been reported in the past week.

Snowpack Summary

Up to 10 cm of new snow may accumulate over the day on Saturday. This new snow will be accompanied by moderate southeast winds forming wind slab on north and west aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.

A late-January weak layer (hard crust, facets, or surface hoar) is buried 80 to 100 cm deep, but the overlying snow lacks slab properties, so it is not currently a concern.

The lower snowpack is strong and bonded.

Weather Summary

Friday Night

Partly cloudy. 10 to 20 km/h west ridgetop wind. Treeline temperature -5 °C.

Saturday

Cloudy with 2 to 10 cm of snow. 20 to 40 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Sunday

Cloudy with 5 to 10 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -2 °C.

Monday

Mix of sun and cloud. 10 km/h northwest ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
