High reliability
: 01 MAY 2024 ore 07:46
Weather forecasts and field observations are reliable
CONSEQUENCES FOR PERSONS OUTSIDE SECURED ZONES
Highly unfavourable conditions. Avoid open terrai.
SNOWPACK STABILITY
The snowpack is poorly bonded and largely unstable in genera.
AVALANCHE TRIGGERING PROBABILITY
Numerous large-sized and often very large-sized natural avalanches can be expected, even in moderately steep terrain.
CONSEQUENCES FOR PERSONS OUTSIDE SECURED ZONES
Unfavourable conditions.Extensive experience in the assessment of avalanche danger is required. Remain in moderately steep terrain / heed avalanche run out zones
SNOWPACK STABILITY
The snowpack is poorly bonded on most steep slopes.
AVALANCHE TRIGGERING PROBABILITY
Triggering is likely even from low additional loads on many steep slopes. In some cases, numerous medium-sized and often large-sized natural avalanches can be expected.
CONSEQUENCES FOR PERSONS OUTSIDE SECURED ZONES
Partially unfavourable conditions.Experience in the assessment of avalanche danger is required. Steep slopes of indicated aspects and altitude zones should be avoided if possible
SNOWPACK STABILITY
The snowpack is moderately to poorly bonded on many steep slopes.
AVALANCHE TRIGGERING PROBABILITY
Triggering is possible, even from low additional loads particularly on the indicated steep slopes. In some cases medium-sized, in isolated cases large-sized natural avalanches are possible.
CONSEQUENCES FOR PERSONS OUTSIDE SECURED ZONES
Mostly favourable conditions. Careful route selection, especially on steep slopes of indicated aspects and altitude zones.
SNOWPACK STABILITY
The snowpack is only moderately well bonded on some steep slopes, otherwise well bonded in genera.
AVALANCHE TRIGGERING PROBABILITY
Triggering is possible primarily from high additional loads, particularly on the indicated steep slopes. Large-sized natural avalanches are unlikely.
CONSEQUENCES FOR PERSONS OUTSIDE SECURED ZONES
Generally safe conditions.
SNOWPACK STABILITY
The snowpack is well bonded and stable in general.
AVALANCHE TRIGGERING PROBABILITY
Triggering is generally possible only from high additional loads in isolated areas of very steep, extreme terrain. Only sluffs and small-sized natural avalanches are possible.
High additional load: group of skiers without spacing, snowmobile/groomer, avalanche blasting
Low additional load: single skier, snowboarder, snowshoe hiker
steep slopes: slopes with an angle of more than about 30 degrees
steep extreme terrain: those which are particularly unfavourable as regards slope angle (usually steeper than about 40°)
MAIN PROBLEM 1: WIND SLAB
SOFT SLAB AVALANCHES
MAIN PROBLEM 2: WET SNOW
Loose wet snow avalanches
LOOSE WET SNOW AVALANCHES
In alpine the recent wind slabs lies on a weak layer, and can fail with a single – person overload leading to medium or small size slab avalanches. These are mainly recorded along northern slopes. At and above the treeline small wet snow sluff are probable, especially along sunniest slopes and at mid-day.
In alpine, pay maximum attention at the wind signs and avoid the recent soft slabs. Approach all steep slopes with caution, the wind affections and the presence of very wet snow on the surface are danger signs.
In alpine there are 10 – 20 cm of recent snow, wind affected and with accumulation especially along northern slopes. Below the shallower layers the old soft snow is composed by faceted crystal. The underlying snowpack is generally well compacted. At and below the treeline the snowpack is entirely wet.
