Lo esencial

Use caution as you transfer into wind-affected terrain.

Human-triggered avalanches are possible.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–1.5

    Wind slabs will be most reactive where they overly surface hoar.

  • Persistent Slabs

    Probabilidad
    Possible - Likely
    Tamaño
    1.5–2.5

    Facets and/or surface hoar buried 50 to 80 cm deep are most prominent on north-facing slopes. Avoid areas with a thin or variable (thin to thick) snowpack.

Avalanche Summary

No avalanche activity has been reported recently. If you observe an avalanche, post a MIN report.

Snowpack Summary

Light snow and southerly winds continue to redistribute recent snowfall. This snow is accumulating on a layer of surface hoar buried 10 to 30 cm deep. This layer of surface hoar is present in the alpine and on aspects that are not exposed to sunlight.

Another layer of facets, surface hoar and/or a crust buried in mid-February is 40 to 80 cm below the snow surface and has been reactive in snowpack tests.

Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth keeping in mind in thin snowpack areas in the alpine.

Weather Summary

Mostly cloudy with 0 to 1 cm of snow. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday

Mostly cloudy with 0 to 1 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Sunday

Cloudy with flurries. 0-5cm of snow. 30 to 40 km/h southwest winds at ridgetop. Treeline temperature -1 °C. Freezing levels reach 1100 m.

Monday

Cloud with flurries 30 to 40 km/h southwest winds at ridgetop. Treeline temperature -1 °C. Freezing levels reach 1100 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
  • Be aware of the potential for large avalanches due to buried weak layers.
