Risk assessment for Wednesday, April 01, 2026
New wind slabs under the NNE Bise wind.
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Above 2000m considerable risk index, lower down moderate index.
Spontaneous releases: some accumulations in the new snow may give way
Skier-triggered: new wind slabs in the new snow
Stability of the snowpack until Wednesday evening, April 01
Typical avalanche situation:
Wind slab
Triggered releases: A few wind slabs in the new snow, they continue to form during the day on Wednesday under the NNE wind. They are friable or even hard, reactive to the passage of a skier. They are more numerous above 2000 m. They are close to the ridges (which will have caught less wind) or behind terrain breaks. The NNE Bise blew hard this Monday; slabs can also locally be found down to the middle of slopes, far from the ridges (often scoured). Fractures are between 20/30 cm and sometimes 50/60 cm in the accumulations. Size 1 to 2, rarely 3 (small to medium, rarely 3). Observables: accumulations, cracks in front of skis, change in snow quality over a short distance. Spontaneous releases: Rare or a few spontaneous releases due to the wind are still possible. Size 1. Rare wet snow slides under a sunny spell on sunny slopes (below rocks), but very limited because of the wind. Size 1.
Snow quality
Snow cover:
Good for the end of March. You can put on skis or snowshoes from 1200/1300 m. Note: absence of base layers below 1500/1600 m on S slopes.
Snow quality this Wednesday:
Below 2000 m: 5/15 cm of new snow resting on still cold snow, presence of a crust at depth except on North slopes. On sunny slopes, the snow is becoming damp at the surface.
Above 2000 m: 5/20 cm of new snow, wind-blown in areas exposed to the Bise. Hard or icy near the ridges.
Numerous cornices and accumulations/drifts.

| French | Translation & Notes |
|---|---|
| Nouvelles plaques à vent sous la Bise de NNE. | New wind slabs under the NNE Bise wind. The 'Bise' is a specific cold, dry wind from the north or northeast common in the Alps. |
| Déclenchements provoqués : | Triggered releases: Refers to avalanches caused by a person (skier, hiker) or artificial means (explosives). |
| Quelques plaques à vent dans la neige récente, elles continuent de se former mercredi en journée sous le vent de NNE. | A few wind slabs in the recent snow; they continue to form during the day Wednesday under the NNE wind. 'Neige récente' is snow that has fallen in the last few days. 'Sous le vent' means leeward (the side sheltered from the wind where snow accumulates). |
| Elles sont friables voir dures, réactives au passage d'un skieur. | They are friable or even hard, and reactive to a skier's passage. 'Friable' often describes soft slabs that crumble easily. 'Réactives' indicates high sensitivity to human weight. |
| Elles sont plus nombreuses au-dessus de 2000 m. | They are more numerous above 2000 m. Specifies the elevation threshold where the risk increases. |
| Elles sont proches des crêtes (qui auront moins pris le vent) ou derrière les ruptures de pente. | They are located close to ridges (which will have seen less wind) or behind terrain breaks. 'Ruptures de pente' (terrain breaks) are classic locations for wind slab accumulation. |
| La Bise de NNE a soufflé fort ce lundi, les plaques peuvent aussi localement se trouver jusqu'en milieu des pentes, loin des crêtes (souvent décapées). | The NNE Bise blew strongly this Monday; slabs can also be found locally as far as the middle of slopes, far from ridges (which are often scoured). 'Décapées' (scoured) means the wind has stripped the snow down to a hard surface or bare ground. |
| Les cassures sont entre 20/30 cm et parfois 50/60 cm dans les accumulations. | Fracture lines are between 20/30 cm and sometimes 50/60 cm in accumulations. 'Cassures' refers to the depth of the crown or fracture wall of the slab. |
| Taille 1 à 2, rarement 3 (petite à moyenne, rarement 3). | Size 1 to 2, rarely 3 (small to medium, rarely 3). Uses the European avalanche size scale. |
| Observables : accumulations, fissures devant les skis, changement de qualité de neige sur une courte distance. | Observables: accumulations, shooting cracks in front of skis, change in snow quality over a short distance. 'Fissures devant les skis' refers to shooting cracks, a primary sign of slab instability. |
| Départs spontanés : | Spontaneous releases: Also known as natural releases, occurring without human influence. |
| Rares voir quelques départs spontanés à cause du vent sont encore possibles. Taille 1. | Rare or even a few spontaneous releases due to the wind are still possible. Size 1. Suggests that the wind itself can trigger small natural avalanches. |
| Rares coulées de neige humide sous une éclaircie dans les versants ensoleillés (sous les rochers), mais très limité à cause du vent. | Rare wet snow slides during sunny spells on sun-exposed slopes (below rocks), but very limited because of the wind. 'Coulées' usually refers to small, loose-snow avalanches (sluffs). |
| Entre nuages et éclaircies, encore bien venté et frais. | Between clouds and sunny spells, still quite windy and cool. Weather summary indicating a mix of sky conditions and persistent wind. |
| Enneigement : | Snowpack coverage: Refers to the general presence and depth of snow. |
| Bon pour une fin mars. | Good for late March. Contextualizing the current snow depth against seasonal norms. |
| On peut chausser skis ou raquettes dès 1200/1300 m. | You can put on skis or snowshoes from 1200/1300 m. 'Chausser' literally means to put on footwear, here referring to the snow line. |
| Attention, absence de sous-couches sous 1500/1600 m en versants S. | Caution: absence of base below 1500/1600 m on S-facing slopes. 'Sous-couches' refers to the old snowpack or base layer. |
| Qualité de la neige ce mercredi : | Snow quality this Wednesday: Description of surface snow conditions. |
| Sous 2000 m : 5/15 cm de neige récente reposant sur une neige encore froide, présence d'une croute en profondeur sauf en Nord. | Below 2000 m: 5/15 cm of recent snow resting on snow that is still cold; presence of a crust at depth except on North aspects. 'Croute' (crust) can act as a sliding layer or indicate previous melting/refreezing. |
| Dans les versants ensoleillés, la neige s'humidifie en surface. | On sunny slopes, the snow is becoming moist on the surface. 'S'humidifie' describes the transition to wet snow conditions due to solar radiation. |
| Au-dessus de 2000 m : 5/20 cm de neige récente, soufflée dans les secteurs soumis à la Bise. | Above 2000 m: 5/20 cm of recent snow, wind-blown in sectors exposed to the Bise. 'Soufflée' means the snow has been transported or altered by wind. |
| Dure ou glacée près des crêtes. | Hard or icy near the ridges. Result of wind scouring and packing. |
| Nombreuses corniches et accumulations/congères. | Numerous cornices and accumulations/snow drifts. 'Congères' is the specific French term for snow drifts or large wind-blown deposits. |
| French Term | English Term | Definition |
|---|---|---|
| Taille 1 | Size 1 | Small avalanche (sluff). Unlikely to bury a person but can knock you off your feet or carry you into terrain traps. |
| Taille 2 | Size 2 | Medium avalanche. Can bury, injure, or kill a person. |
| Risque 2 - Limité | 2 - Moderate | Snowpack is moderately well bonded on some steep slopes, otherwise generally well bonded. Triggering is possible with high additional loads, particularly on indicated steep slopes. Large natural avalanches unlikely. |
| Risque 3 - Marqué | 3 - Considerable | Snowpack is moderately to poorly bonded on many steep slopes. Triggering is possible even from low additional loads, particularly on indicated steep slopes. In certain situations, some large natural avalanches are possible. |
| Risque 4 - Fort | 4 - High | Snowpack is poorly bonded on most steep slopes. Triggering is likely even from low additional loads on many steep slopes. In some situations, many medium and sometimes large natural avalanches are expected. |
| Indices de risque | Risk Indices | The European Avalanche Danger Scale: 1 (Low) = generally stable; 2 (Moderate) = possible on steep slopes; 3 (Considerable) = triggering possible even by a single skier; 4 (High) = likely even from low loads, natural releases expected; 5 (Very High) = widespread natural avalanches, extremely dangerous. |
| Plaque à vent | Wind slab | A cohesive layer of wind-deposited snow on the lee side of ridges, crests, or obstacles. Often hard or stiff on the surface but resting on a weaker layer beneath. Can be triggered by a single skier. |
| Avalanche de neige humide | Wet snow avalanche | An avalanche caused by liquid water weakening the bonds between snow grains, due to rain, warm temperatures, or solar radiation. Typically heavy, dense, and slow-moving but extremely powerful and destructive. |
| Départ spontané | Natural release | An avalanche that releases without human intervention, triggered by natural factors such as new snowfall, wind loading, warming, or rain. Indicates the snowpack is unstable enough to fail on its own. |
| Déclenchement provoqué | Skier-triggered release | An avalanche caused by the weight of a person (skier, snowboarder, hiker) or by explosives. The additional load collapses a weak layer, causing the slab above to fracture and slide. |
| Manteau neigeux | Snowpack | The total accumulation of all snow layers on the ground. Its structure — the arrangement and bonding of different layers — determines avalanche risk. |
| Corniche | Cornice | An overhanging mass of wind-deposited snow on the edge of a ridge or crest. Can break off unexpectedly and trigger avalanches on the slope below. |
| Rupture de pente | Terrain break | A point where the slope angle changes abruptly (convexity or concavity). These features concentrate stress in the snowpack and are common fracture initiation points for slab avalanches. |
| Cassure | Crown / Fracture line | The line along which a slab avalanche fractures and separates from the stable snow above. The height of the crown wall indicates the slab thickness and avalanche severity. |
| Plaque | Slab | A cohesive layer of snow that can fracture and slide as a unit when a weak layer beneath it collapses. Slabs can be soft or hard, and vary from small to enormous. |
| Fissures | Shooting cracks | Visible cracks propagating through the snow surface, indicating significant instability in the snowpack. A clear sign of dangerous conditions. |
| Bise | Bise wind | A cold, dry northeasterly wind common in Switzerland. The Bise can transport snow and form dangerous wind slabs, particularly on sheltered slopes. |
| neige récente | recent snow | Snow that has fallen within the last few days and has not yet undergone significant settlement or transformation. |
| friable | friable / soft-slab | A term describing snow that is easily crumbled, often referring to a less cohesive soft wind slab. |
| décapée | scoured | Describes terrain where the wind has removed the surface snow, often down to a hard crust or the ground. |
| croûte | crust | A hardened layer on the surface or within the snowpack, usually formed by sun, rain, or wind. |
| neige humide | wet/moist snow | Snow that contains liquid water, often caused by warm temperatures or solar radiation. |
| congère | snow drift | A large accumulation of snow deposited by the wind, typically in the lee of an obstacle or terrain break. |
