Danger level


Avalanche Problem
Wet snow


Only isolated avalanche prone locations for small releases

Avalanche danger is LOW. In isolated cases, small loose-snow avalanches or glide-snow avalanches can release. For triggering a generally small-sized slab avalanche, greater additional loading is necessary.

Snowpack

The shallow snowpack is quite compact by and large. Marked weak layers are not much evident. Most likely is if the snowpack at ground level or else the uppermost layer release if not sufficiently bonded to the snow beneath it.

Tendency

On Thursday night a cold front will bring strong-velocity W/NW winds and some snowfall. Fresh, shallow snowdrift accumulations can be freshly formed.

Foehn-induced snowdrift accumulations easily triggered

Avalanche danger levels above the timberline are CONSIDERABLE, below that altitude danger is LOW. The freshly generated snowdrift accumulations can trigger a small-to-medium slab avalanche even by minimum additional loading. Most of the danger zones (both near to and distant from ridgelines, and behind protruberances in the landscape) occur on north and east facing slopes and in wind-loaded gullies and bowls. Most critical are transitions from shallow to deeper snow. In isolated cases, avalanches can fracture in the old snow and grow to larger size. Mostly small glide-snow avalanches and wet loose-snow avalanches can trigger naturally, particularly at intermediate altitudes.

Snowpack

The snowpack is highly varied and still with too little snow for this juncture of the season. Crests and ridges are often windblown, gullies and bowls filled to the brim with snow. Weak layers occur as faceted crystals atop crusts and near-surface (beneath fresh snow and drifts) as well is inside the old snow.

Tendency

On Thursday night a cold front will bring strong-velocity W/NW winds and some snowfall. Fresh, shallow snowdrift accumulations can be freshly formed.

Caution: foehn-induced snowdrifts

Avalanche danger above 2000m is MODERATE, below that altitude danger. Snowdrift accumulations near to and distant from ridgelines on north and east-facing slopes can trigger a small-to-medium slab avalanche, in some steep places even by minimum additional loading. Above 2200m, isolated weak layers in the old snowpack can be triggered and avalanches can become correspondingly larger. Most dangerous of all are transitions from shallow to deeper snow and entries into gullies filled with drifts. Isolated glide-snow avalanches and small wet loose-snow avalanches can trigger naturally.

Snowpack

The border to the old snowpack can be a weak layer for a slab avalanche. In additional, above 2200m there are several weak layers in the old snow, of faceted crystals which are often prone to triggering.

Tendency

On Thursday night a cold front will bring strong-velocity W/NW winds and some snowfall. Fresh, shallow snowdrift accumulations can be freshly formed.
