Avalanche conditions are expected to improve as cooler temperatures follow the wet weekend storm.

Proceed cautiously, the status of buried weak layers is uncertain.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Observations have been limited by poor visibility. Preliminary observations from the storm over the weekend include:

  • A natural loose wet cycle size 2-2.5 up to 2100 m.

  • A natural storm and/or wet slab cycle in the alpine and treeline; size 1-2 observed visually, and numerous audibles suspected to be very large.

  • Rider-triggered slabs propagated easily in small features, size 1-1.5. Most ran within the recent storm snow, two on the February weak layer.

Snowpack Summary

Dry, low density snow falls ontop of 20 to 50 cm of heavy, moist snow from the weekend. At upper elevations, the recent snow has been affected by previous strong wind. Below 1800 m, a crust is forming over a wet upper snowpack.

Three problematic layers persist in the mid-snowpack.

  • One or two surface hoar layers buried in February are found 60 to 120 cm below the surface, and in some areas these sit on a thin crust.

  • A deeper, widespread layer buried in late January, made up of surface hoar, facets, and/or a crust, is buried 100 to 180 cm deep. Surface hoar within this layer is most preserved and largest in sheltered terrain at treeline and below.

Weather Summary

Sunday Night
Mostly cloudy. 2 to 10 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -9 °C.

Monday
Mix of sun and clouds. 2 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -11 °C.

Tuesday
Mix of sun and clouds. 2 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -11 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Be mindful that deep instabilities are still present and have produced recent large avalanches.
  • Uncertainty is best managed through conservative terrain choices.
  • Be especially cautious as you transition into wind-affected terrain.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
