Kernpunkte

Seek out sheltered powder for better, safer riding.

Watch for wind-loaded pockets as this is where you'll trigger an avalanche.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5

    New wind slabs may be sliding on a buried crust. Test wind slabs on small features before committing to large slopes that the wind has loaded.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5

    This problem is likely small and only in steep, sunny slopes sheltered from the wind.

Avalanche Summary

A few small (size 1) human-triggered wind slab avalanches were reported in the alpine on Friday by our neighbours in the USA. They seem to be running on a crust, that may have weak facet crystals above.

Please consider sharing any observations you have on the Mountain Information Network.

Snowpack Summary

Saturday's small amount of new snow adds to any wind loading that occurred on Friday loading a buried crust; possibly with small, weak facets on top. This caught riders off guard on Friday.

The bottom of the snowpack contains several crusts that have not been a concern.

Around 100 cm of snow can be found at treeline. This diminishes rapidly below about 1500 m.

Weather Summary

Saturday Night

Cloudy. 20 to 30 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Sunday

Mostly sunny. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2700 m.

Monday

Sunny. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 3200 m.

Tuesday

Sunny. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 3200 m.

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Carefully evaluate steep lines for wind slabs.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
