Kernpunkte

Exercise caution in areas that receive new snow, especially at higher elevations where winds may redistribute the snow into deeper slabs.

    In areas, new snow and wind may form thin wind slabs at higher elevations. These may be a particular concern when overlaying a smooth melt-freeze crust.

Moderate

Avalanche Summary

No recent avalanche activity has been reported. However, field observations are currently very limited.

Snowpack Summary

Anticipate crusty snow surfaces in all but north-facing alpine terrain.

Some areas will receive new snow overnight, which may be redistributed into thin wind slabs at higher elevations.

A series of crusts exist in the upper snowpack.

Weather Summary

Monday Night

Mostly cloudy with 0 to 5 cm of snow. Freezing level dropping to the valley bottom overnight. 30 to 50 km/h northeast ridgetop wind. Treeline temperature -8 °C.

Tuesday

Mostly cloudy with 0 to 10 cm of snow (highest snowfall values expected along in the east of the region). Freezing level 1200 m. 30 to 50 km/h northeast ridgetop wind. Treeline temperature -8 °C.

Wednesday

Mostly sunny. 10 to 30 km/h northeast ridgetop wind. Treeline temperature - 5 °C. Freezing level 1500 m.

Terrain and Travel Advice

  • Carefully monitor the bond between the new snow and old surface.
  • Be alert to conditions that change with aspect and elevation.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
