Avalanche Summary

A few small (size 1) avalanches were reported over the past few days including:

  • Wet loose avalanches on sun-exposed slopes and at low elevations.

  • Human-triggered wind slabs on north-facing slopes.

Looking forward, wet loose avalanches will become more likely as skies clear and the freezing level rises.

Snowpack Summary

10 to 20 cm of dry snow may be found on north-facing slopes. Surfaces will gradually become wet over the next few days with rising freezing levels and sun exposure.

The facet/crust layer that caused large avalanches in March is buried 100 to 150 cm deep and is unlikely to trigger under the current conditions.

Friday

Mix of sun and cloud. 35 km/h southwest ridgetop wind. Treeline temperature +3 °C. Freezing level 2400 m.

Saturday

Sunny. 15 km/h west ridgetop wind. Treeline temperature +6 °C. Freezing level 2800 m.

Sunday

Sunny. 15 km/h west ridgetop wind. Treeline temperature +8 °C. Freezing level 3200 m.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Minimize your exposure time below cornices.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Problems

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.
