Danger level
Danger Level 3 - Considerable above 2500m
Danger Level 2 - Moderate above 2500m
Avalanche Problem
New snow above the treeline, N-NE-E-W-NW
Wet snow above 2000m, N-NE-E-SE-S-SW-W-NW

In all aspects and on very steep slopes more moist loose snow avalanches are possible, but they will be mostly small. The fresh snow can be released, especially by large additional loads in all aspects above approximately 2500 m.

As a consequence of warming during the day individual natural avalanches are possible, but they will be mostly small. These can in isolated cases penetrate down to the ground and reach medium size. In particular, however, the wind slabs must be taken into account. They can be released, mostly by large loads in isolated cases. Above the tree line the likelihood of avalanches being released is greater. The avalanche prone locations are to be found on steep slopes of all aspects and adjacent to ridgelines and in gullies and bowls.

Snowpack

The fresh snow and wind slabs remain in some cases prone to triggering above approximately 2000 m. The clearly visible wind slabs of last week represent the main danger. Below approximately 1500 m hardly any snow is lying.

Danger level
Danger Level 1 - Low above 2200m
Danger Level 2 - Moderate above 2200m
Avalanche Problem
Wet snow above 2200m, N-NE-E-SE-S-SW-W-NW

Wet snow slides and avalanches are the main danger. This applies below approximately 2200 m.

As a consequence of the rain, the likelihood of wet snow slides and avalanches being released will increase a little. Mostly small wet loose snow avalanches are possible below approximately 2000 m, this applies even in case of a small load. Caution is to be exercised in particular on extremely steep slopes. In addition a certain danger of wet slab avalanches exists, in particular on very steep shady slopes in areas close to the tree line.

Snowpack

dp 3: rain

In some localities up to 10 cm of snow. will fall until the early morning. Over a wide area 5 to 10 cm of snow. will fall from early morning. Up to 2000 m rain will fall. The wind will be light. Isolated avalanche prone weak layers exist in the bottom section of the old snowpack on shady slopes. Here individual wet slab avalanches are possible as the penetration by moisture increases. This applies especially in areas close to the tree line. The fresh snow is bonding well with the old snowpack. The snowpack will be wet all the way through at intermediate altitudes. At low altitude hardly any snow is lying.

Tendency

The danger of wet snow slides and avalanches will persist.

Danger level
Danger Level 1 - Low above 2200m
Danger Level 2 - Moderate above 2200m
Avalanche Problem
Wet snow above 2000m, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2200m, N-NE-E-SE-S-SW-W-NW

Up to 2000 m rain will fall. Wet and gliding avalanches are the main danger.

As a consequence of the rain, the likelihood of gliding avalanches and wet snow slides being released will increase a little. More small to medium-sized wet loose snow avalanches are possible below approximately 2000 m, this applies even in case of a small load. Caution is to be exercised in particular on extremely steep slopes. In addition a latent danger of gliding avalanches exists. This applies in all aspects below approximately 2200 m.

Snowpack

dp 3: rain
dp 2: gliding snow

In some localities up to 10 cm of snow. will fall until the early morning. Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall from early morning, especially south of the Inn. Rain below approximately 2000 m. The wind will be light. The fresh snow is bonding well with the old snowpack. The snowpack will be wet all the way through at intermediate altitudes. At low altitude hardly any snow is lying.

Tendency

The avalanche danger will persist. Wet loose snow avalanches and gliding avalanches are still possible.

Danger level
Danger Level 2 - Moderate
Avalanche Problem
Wet snow above the treeline, N-NE-E-W-NW
Gliding snow above the treeline, N-NE-E-SE-S-SW-W-NW

Small avalanches and moist snow slides are possible in isolated cases as before.

Individual natural avalanches are possible, but they will be mostly small. Above approximately 2000 m the likelihood of avalanches being released is greater. In addition the wind slabs must be taken into account. These can in very isolated cases be released, in particular by large loads, but they will be small in most cases. The avalanche prone locations are to be found in particular in gullies and bowls in all aspects and adjacent to ridgelines above approximately 1800 m.

Snowpack

The fresh snow and wind slabs remain in some cases prone to triggering above approximately 1800 m. The clearly visible wind slabs of last week represent the main danger. Below approximately 1800 m from a snow sport perspective, insufficient snow is lying.

Danger Level 2 - Moderate
Avalanche Problem
Wet snow above 2500m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above 2500m, N-NE-W-NW

Natural wet avalanches are possible already in the late morning. Wind slabs in high Alpine regions.

In all regions and below approximately 2500 m small and medium-sized moist and wet avalanches are possible. As a consequence of the rain, the likelihood of moist and wet avalanches being released will increase. The mostly small wind slabs of the last few days must be evaluated with care and prudence in particular on west to north to northeast facing aspects above approximately 2500 m. Single backcountry tourers can release avalanches in some places, with a large load in most cases.

Snowpack

Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will freeze very little and will already be soft in the early morning. Up to 1800 m rain will fall in some localities. As the day progresses as the penetration by moisture increases there will be an increase in the danger of moist and wet snow slides within the current danger level. This applies in all aspects below approximately 2500 m. Isolated avalanche prone weak layers exist in the bottom section of the old snowpack on shady slopes. The mostly small wind slabs of the last few days are barely recognisable because of the poor visibility.

Tendency

Wet snow slides and avalanches are still possible.

Avalanche Problem
New snow above 2000m, N-NE-E-W-NW
Wet snow, N-NE-E-SE-S-SW-W-NW

In all aspects and on very steep slopes more moist loose snow avalanches are possible, but they will be mostly small. The fresh snow can be released, especially by large additional loads in all aspects above approximately 2500 m.
