Problemas de aludes

  • Persistent weak layers

    • Todas las altitudes
  • Wind slab

    • Todas las altitudes

Tendency

Quite windy for a brief spell - N/NW. Temperatures will rise. At 2000 m from -3 to +1 degree. Avalanche danger will diminish.

Avalanche Activity

At high altitudes, considerable avalanche danger still prevails. Avalanche prone locations occur in wind-loaded steep terrain, also distant from ridgelines and particularly behind abrupt discontinuities in the terrain, in gullies and bowls. Size and spread of the danger zones increase with ascending altitude. Whumpf noises and glide cracks in the snowpack surface are signals of danger. Also remote triggerings and naturally triggered avalanches are possible. If avalanches fracture down to these layers they can grow to large size. Below 2200 m on sunny steep grassy slopes, glide-snow avalanches are possible during the day.

Snowpack Structure

Fresh snow and snowdrifts from the beginning of the week lie deposited atop unfavourable layers, often of surface hoar, melt-freeze crusts or softened layers. Bonding of fresh snow and drifts to these layers and also inside the snowpack itself is frequently poor. At high altitudes on shady slopes there are deeply embedded layers inside the snowpack which are weak, and these layers are not visible to the naked eye.

Weather Synopsis

Nocturnal hours: dry and clear skies, very cold. Friday. The current conditions will persist, brilliant sunshine, only little cloud. On Friday night clouds from the north will move in, but no precipitation is expected. At 2000 m: -6 to -3 degrees. Winds shifting to northerly, light to moderate.
