Assess for new wind slabs as you gain elevation

Wind slabs could be touchy due to the underlying weak layers

Confidence

Moderate

Avalanche Summary

At the time of publishing, no new avalanches were reported in the past week. It’s possible that human triggered avalanches could have occurred late in the day on Saturday.

Snowpack Summary

Up to 20 cm of new snow may accumulate by Sunday morning. This new snow will be accompanied by moderate to strong 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 60 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

Saturday Night

Cloudy with 5 to 15 cm of snow. 30 to 50 km/h southeast ridgetop wind. Treeline temperature -2 °C.

Sunday

Cloudy with 5 cm of snow. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -1 °C.

Monday

Mostly cloudy with up to 5 cm of snow. 10 km/h variable ridgetop wind. Treeline temperature -2 °C.

Tuesday

Mostly cloudy with trace amounts of snow. 15 km/h southeast 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.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Closely monitor how the new snow is bonding to the old surface.

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.
