Avalanche Summary

Small wet loose avalanches (size 1 to 1.5) have been reported the past few days, especially on sun-exposed slopes. Small wind slabs may have occurred during stormy weather on Wednesday.

Field observations are currently very limited in this region. Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

5 to 15 cm of recent snow sits above crusts and hard snow. Isolated wind slabs may exist in steep alpine terrain. Melt-freeze crusts near the surface exist to mountaintops on sun-exposed slopes.

Surfaces will transition to wet snow with daytime warming and generally refreeze at night.

Cornices are large and may become weak with daytime warming.

Weather Summary

Wednesday Night

Partly cloudy with 1 to 3 cm snow. 30 km/h northwest ridgetop wind. Treeline temperature -4 °C. Freezing level 800 m.

Thursday

Clearing skies throughout the day. 15 km/h northeast ridgetop wind. Treeline temperature +2 °C. Freezing level 1700 m.

Friday

Sunny. 15 km/h southeast ridgetop wind. Treeline temperature +6 °C. Freezing level 2000 m.

Saturday

Mostly cloudy with 1 to 5 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature +3 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Be alert to conditions that change with aspect and elevation.

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.
