Start your day early and watch the crust closely.

As it breaks down, reduce your exposure to avalanche terrain.

Avalanche Summary

Wet loose avalanches have been occurring daily on steep slopes facing the sun. Mostly small, but some large avalanches (size 2 to 3).

Snowpack Summary

A thin surface crust is expected to cover up to 25 cm of recent snow at upper elevations. This snow overlies a robust crust buried around 20 to 30 cm, which is everywhere except northerly aspects in the alpine.

The mid and lower snowpack has no layers of concern.

Saturday

Mix of sun and cloud. 10 to 20 km/h west ridgetop wind. Treeline temperature 5 °C. Freezing level 2500 m.

Sunday

Mix of sun and cloud. 10 km/h northwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2400 m.

Monday

Cloudy with 5 to 10 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2100 m.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Wet Slabs

Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.

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.

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.
