Lo esencial

There is still potential for small avalanches to step down and create large destructive avalanches.

Stick to conservative terrain, free from overhead hazard.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2

    Fresh and reactive wind slabs exist at upper elevations. Watch for wind-loaded features near ridgeline.

  • Persistent Slabs

    Probabilidad
    Possible - Likely
    Tamaño
    2–3

    Facets and/or surface hoar buried 40 to 80 cm deep are most prominent at upper elevations where no surface crust has formed. Surface instabilities or large triggers may step down to these deeper layers.

Moderate

Avalanche Summary

A large avalanche was reported in the Evelyn area on a northeast aspect on Saturday. Check out the details in this MIN.

If you do observe an avalanche, please share your observations on the Mountain Information Network.

Snowpack Summary

Up to 20 cm of new snow covers variably wind-affected snow in open terrain at upper elevations. A crust is found up to 2000 m and higher on solar slopes.

Below 1100 m the snowpack is wet and unconsolidated.

Two layers of concern currently exist in the upper-mid snowpack.

  • A layer of surface hoar that formed in early March can be found at a depth of 60 to 100 cm.

  • A layer of facets, surface hoar, and/or a crust from mid-February is buried 120 to 200 cm deep.

The remainder of the snowpack is well consolidated, and there are no current concerns.

Weather Summary

Cloudy with 1 to 2 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Monday

Cloudy with 1 to 2 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 m.

Tuesday

Mix of sun and cloud. 30 to 50 km/h southwest ridgetop wind. Treeline temperature 1°C. Freezing level 1600 m.

Wednesday

Mix of sun and cloud. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -1°C. Freezing level 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
