Avalanche danger above the timberline is moderate, below that altitude danger is low. Snowdrifts are the main problem. From place to place, small slab avalanches can be triggered even by minimum additional loading. Avalanche prone locations are found in steep ridgeline terrain in N/E aspects as well as in wind-loaded gullies and bowls. As a consequence of solar radiation small loose snow avalanches can in addition be released in steep rocky terrain. At intermediate altitudes small glide-snow avalanches can trigger naturally on very steep slopes with smooth ground.
Snowpack
Weak to moderate winds accumulated small-scale snowdrifts at high altitude. Starting from timberline altitude, weak layers that are prone to triggering are from place to place still embedded in the snowdrifts. At intermediate altitude the new snow and snowdrifts have bonded well with the moist old snowpack surface. At high altitudes the bonding is poorer, especially on the shady side. At intermediate altitudes the old snowpack is thoroughly moist, frequently wet at the ground. Caused by solar radiation even the new snow will become moist as the day progresses. Up to the timberline in south aspects the new fallen snow is mainly deposited on bare ground.
Tendency
Avalanche danger levels will recede slowly.

Avalanche Problem
Wind slab
Situation mostly favorable. Isolated small-scale snowdrifts prone to triggering.
Avalanche danger is low. Snowdrifts can be problematic. In steep east-facing ridgeline terrain isolated small snowdrift accumulations can be triggered by minimum additional loading. Dangers of being swept along and of taking a fall outweigh those of being buried in snow masses. As a consequence of solar radiation small loose snow slides can release in steep rocky terrain. On very steep slopes over smooth ground, it cannot be excluded that small glide-snow avalanches can release spontaneously.
Snowpack
The new snow has bonded well with the moist old snowpack surface. Small snowdrifts accumulated at higher altitude. In isolated cases, snowdrift accumulations can contain intermediate layers that are prone to triggering. The old snowpack is completely soaked, often wet at the ground. Caused by solar radiation even the new snow will become moist as the day progresses. Up to the timberline in south aspects the small quantities of new fallen snow are mainly deposited on bare ground.
Tendency
Avalanche danger levels will remain low.

Caution: small-scale snowdrifts.
Avalanche danger above 1800 m is moderate, below that altitude danger is low. Snowdrifts are the main problem. From place to place, small slab avalanches can be triggered even by minimum additional loading. Avalanche prone locations are mainly found at higher altitudes in steep north-/east-facing terrain adjacent to ridgelines and in wind-loaded gullies and bowls. As a consequence of solar radiation small loose snow avalanches can in addition be released in steep rocky terrain. At intermediate altitudes it cannot be excluded that small glide-snow avalanches trigger naturally on very steep slopes with smooth ground.
Snowpack
Weak to moderate winds accumulated small-scale snowdrifts at high altitude. In some places at higher altitudes, weak layers that are prone to triggering persist in the snowdrifts. At intermediate altitude the new snow and snowdrifts have bonded well with the moist old snowpack surface. At high altitudes the bonding is poorer, especially on the shady side. At intermediate altitudes the old snowpack is thoroughly moist, wet at the ground in places. Caused by solar radiation even the new snow will become moist as the day progresses. Up to the timberline in south aspects the new fallen snow is mainly deposited on bare ground.
