Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

Over the past few days numerous natural cornice failures were reported. Even without triggering slabs on the slopes below debris piles were up to size 2.5.

Numerous wet and dry loose avalanches have been observed in steep or extreme terrain. These avalanches have grown in size, up to size 2.

Snowpack Summary

Surface conditions are highly variable:

·        In exposed alpine and treeline terrain previous wind may have scoured ridge tops and formed small wind slabs in lee features.

·        Sheltered treeline features may still hold dry snow.

·        A crust exists on or near the surface on sun exposed slopes and all other aspects below 2300 m.

Convective flurries over the past two weeks have deposited highly variable amounts of snow above the atmospheric river crust. Depending on drainage and elevation, you may find 30 to 100 cm above this crust, which extends to at least 2300 m.

Older weak layers are unreactive and buried at least 150 cm deep.

Weather Summary

Saturday
Mostly cloudy. 1 cm of snow possible. 30 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1700 m.

Sunday

Monday
Mix of sun and clouds. 1 mm of rain at treeline, snow in the alpine. 30 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2600 m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Carefully evaluate steep lines for wind slabs.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
