Lo esencial

Forecast snow and wind will form storm slabs most reactive to human triggers in wind affected terrain at upper elevations.

Make conservative terrain choices and avoid overhead hazard.

Problemas de aludes

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–2.5

    Cornices loom over ridgetops and may be triggered by rapid snow loading or people traveling along ridgelines.

Avalanche Summary

On Saturday, no new avalanches were reported.

Forecast snow and wind are expected to form reactive storm slabs at upper elevations.

Snowpack Summary

Forecast 25 to 35 cm of snow (above 1300 m, rain below) on Sunday night will form storm slabs sitting on a moist snow surface. The storm slabs are expected to be most reactive in wind affected terrain at upper elevations.

The snowpack is strong and bonded, but melting quickly at lower elevations.

Weather Summary

Sunday Night

Snow, 25 to 35 cm above 1300 m, rain below. 30 to 40 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1700 m.

Monday

Snow, 10 to 20 cm above 1000 m. 30 to 40 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Tuesday

Snow, 20 to 30 cm. 30 to 40 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1400 m.

Wednesday

Mostly cloudy with isolated flurries, 0 to 5 cm snow. 10 to 20 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Avoid travelling on slopes below cornices.
