Risk assessment for Sunday, 26 April 2026
DEEP WETTING CONTINUES.
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Low risk index evolving to moderate.
Naturally triggered avalanches: rare but possible large releases in wet snow.
Skier-triggered releases: wet snow under the skis.
Stability of the snow cover until Sunday, 26 April evening
Typical avalanche situation:
Wet snow
Naturally triggered avalanches: rare wet snow avalanches on sunny slopes. They occur after several hours of sun exposure, mostly point-release avalanches (pear-shaped sluffs), small avalanches. South-facing slopes are more stabilized in this already well-advanced season with dense snow of the firn type throughout the thickness of the snow cover. On high-altitude East and West aspects, as well as North, the wetting gains in depth. A rare linear release is possible when the wetting reaches a buried layer prone to triggering, a large avalanche (size 3) becomes possible. Skier-triggered releases: unlikely except for wet (rotten) snow avalanches under the skis when cutting an overly wet slope. - In strictly North aspects at high altitude (>3000 m), a very rare cold snow slab may persist. Observable: buried layer less dense than at the surface. Others: cornice falls reported.
Snow quality
Snow conditions: below average for the season, the heat is persistently excessive and the snow is melting rapidly.
Skiable limit: around 1700 m in the north, 2000 m in the south on gentle slopes, much higher on steep south slopes.
Snow quality: spring snow after a good overnight refreezing. Hard snow in the first hours of the day then quickly "velvet" from morning to mid-day depending on aspects and altitudes. Snow becomes rotten quickly in the morning on East aspects and generally everywhere after noon. You have to climb above 2800/3000 m in strictly North aspects (somewhat steep) to find very light new snow still good for skiing.

| French | Translation & Notes |
|---|---|
| L'HUMIDIFICATION EN PROFONDEUR CONTINUE. | Deep wetting continues. *Humidification* refers to the process of water (from melt or rain) percolating into the snowpack. *En profondeur* means deep within the layers, which is a significant structural change. |
| Départs spontanés : rares avalanches de neige humide dans les pentes ensoleillées. | Natural releases: rare wet snow avalanches on sunny slopes. *Départs spontanés* is the standard term for natural (non-human triggered) avalanches. *Pentes ensoleillées* (sunny slopes) highlights that solar radiation is the primary trigger. |
| Elles se produisent après plusieurs heures d'action du soleil, départs majoritairement ponctuels (coulées en "poires"), petites avalanches. | They occur after several hours of solar action, mostly point releases ("pear-shaped" sluffs), small avalanches. *Ponctuels* (point-source) refers to avalanches that start from a single point and fan out, shaped like a pear (*poire*). This is typical for loose wet snow. |
| Les pentes sud sont davantage stabilisées en cette saison déjà bien avancée avec une neige dense de type névé sur toute l'épaisseur du manteau. | South-facing slopes are more stabilized this late in the season, with dense firn-like snow throughout the entire thickness of the pack. *Névé* refers to old, dense, multi-year snow or very consolidated spring snow. On south slopes, the repeated melt-freeze cycles have created a homogenous, stable structure. |
| En versants Est et Ouest d'altitude, ainsi qu'en Nord, l'humidification gagne en profondeur. | On high-altitude East and West aspects, as well as North aspects, the wetting is penetrating deeper. *Gagne en profondeur* (gains in depth) indicates that the meltwater is moving past the surface and into deeper, potentially weaker layers of the snowpack. |
| Un rare départ linéaire est possible quand l’humidification atteint une couche fragile enfouie, une grande avalanche (taille 3) devient possible. | A rare linear (slab) release is possible when the wetting reaches a buried weak layer; a large avalanche (size 3) becomes possible. *Départ linéaire* is the French term for a slab avalanche. *Couche fragile enfouie* (buried weak layer) is the critical structural concern here. Size 3 refers to an avalanche that can bury a car or destroy a small building. |
| Déclenchements provoqués : peu probables sauf avalanche de neige humide (pourrie) sous les skis en coupant une pente trop humidifiée. | Triggered releases: unlikely except for wet snow (rotten) avalanches under skis when crossing a slope that is too wet. *Neige pourrie* (rotten snow) describes snow that has lost all cohesion due to water saturation. *Coupant* (cutting) refers to the action of a skier traversing across a slope. |
| En plein Nord de haute altitude (>3000 m), une très rare plaque en neige froide peut subsister. | In true North high-altitude aspects (>3000 m), a very rare cold snow slab may persist. *En plein Nord* means directly North-facing. *Plaque en neige froide* refers to a dry snow slab, contrasting with the wet snow problems found elsewhere. |
| Observable : couche enfouie moins dense qu'en surface. | Observable: buried layer less dense than the surface. This describes a 'upside-down' snowpack structure where a harder slab sits on top of softer, less dense snow, a classic setup for slab avalanches. |
| Autres : chutes de corniches signalées. | Others: cornice falls reported. *Corniches* are overhanging ridges of snow. Heat causes them to weaken and collapse, which can trigger larger avalanches on the slopes below. |
| Matinée ensoleillée puis quelques nuages en cours de journée. | Sunny morning followed by a few clouds during the day. *En cours de journée* is a common phrase meaning 'as the day progresses'. |
| Enneigement : déficitaire pour la saison, la chaleur est durablement excessive et la neige fond à vue d'œil. | Snowpack: below average for the season, the heat is persistently excessive and the snow is melting visibly. *Déficitaire* means there is a deficit (less snow than normal). *À vue d'œil* is an idiom meaning 'at a glance' or 'right before one's eyes', emphasizing rapid melting. |
| Limite skiable : vers 1700 m en nord, 2000 m en sud en pente douce, bien plus haut en pente sud raide. | Skiable limit: around 1700 m on North aspects, 2000 m on South aspects on gentle slopes, much higher on steep South slopes. *Pente douce* (gentle slope) vs. *pente raide* (steep slope). The limit is higher on steep south slopes because they get the most direct sun, causing faster melting. |
| Qualité de la neige : neige de printemps après un bon regel nocturne. | Snow quality: spring snow after a good overnight freeze. *Regel nocturne* is the most important concept for spring skiing; it's the night-time freezing that creates a safe, hard crust. |
| Neige dure aux premières heures du jour puis rapidement moquette de la matinée à la mi journée suivant orientations et altitudes. | Hard snow in the early hours, then quickly "moquette" (corn snow) from morning to midday depending on aspects and altitudes. *Moquette* literally means 'carpet'. In skiing, it refers to the thin, soft surface layer of melted snow over a hard base (corn snow), which is highly desirable. |
| Neige pourrie rapidement le matin en versant Est et généralement partout après midi. | Snow becomes "rotten" quickly in the morning on East aspects and generally everywhere in the afternoon. East slopes catch the early morning sun, so they transition from frozen to 'rotten' first. |
| Il faut monter au-dessus de 2800/3000 m en plein Nord (un peu raide) pour trouver de la neige poudreuse encore bonne à skier. | You have to climb above 2800/3000 m on true North aspects (somewhat steep) to find powder snow still good for skiing. *Neige poudreuse* is powder snow. This sentence explains that you have to go very high and stay in the shade to find winter-like conditions. |

|---|---|---|---|
| Départ spontané | Naturally triggered avalanches | Avalanche not caused by external forces, e.g. snowfall or loss in firmness due to weather conditions. | European Avalanche Warning Services |
| déclenchable | Skier-triggered releases | 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. | AvalancheClarity Static Glossary |
| Fragile | Prone to triggering | A snowpack or snow layer that tends to release from additional loading. | European Avalanche Warning Services |
| Neige poudreuse | Very light new snow | New fallen snow with very low density: typically 30 kg/m³ (champagne powder, diamond snow). | European Avalanche Warning Services |
| Adret | South-facing slopes | The sunny, south-facing side of a mountain. Snow becomes wet more quickly due to solar radiation. | AvalancheClarity Static Glossary |
| Avalanche de neige mouillèe | Wet snow avalanches | Avalanche of wet snow masses. | European Avalanche Warning Services |
| Enneigement | Snow conditions | The depth and distribution of snow on the ground across a mountain range. Varies with elevation, aspect, and snowfall history. | AvalancheClarity Static Glossary |
| marqué | 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. | European Avalanche Warning Services |
| Pente ensoleillée | Sunny slopes | Terrain heavily impacted by direct solar radiation. | European Avalanche Warning Services |
| Regel | Refreezing | Overnight freezing of the snow surface forming a hard crust. Refreezing temporarily stabilises the snowpack but strength decreases with daytime warming. | AvalancheClarity Static Glossary |
| Manteau neigeux | Snow cover | Snow deposited on the ground in a multiplicity of layers. | European Avalanche Warning Services |
| Hauteur de neige | Snow depth | Thickness of the snowpack measured vertically. | European Avalanche Warning Services |
| Stabilisé | Stabilized | See: Increasing firmness (of a snow layer) | European Avalanche Warning Services |
| Stabilité | Stability | The strength of a snowpack to withstand internal and external disturbances.Stability is determined by firmness vs. stress inside a snow layer. | European Avalanche Warning Services |
| très fort | very high | Snowpack is generally unstable. Many large natural avalanches are expected, even on moderately steep terrain. Extremely dangerous conditions — avoid all avalanche terrain. | European Avalanche Warning Services |
| Neige fraîche | New snow | The new snow problem is related to current or recent snowfall. The additional loading on the existing snowpack or a lack of cohesion in the newly fallen snow can cause avalanche activity. The problem is widely present, often in all aspects and lasts usually until a few days after the snowfall event. | European Avalanche Warning Services |
| Neige humide | Wet snow | The wet snow problem is related to the weakening of the snowpack due to the presence of liquid water. Water infiltrates the snowpack due to high radiation impact (sunshine) which leads to melt or rain (advecting energy into the snowpack leading to melt as well). | European Avalanche Warning Services |
| limité | 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. | European Avalanche Warning Services |
| Corniche | Cornice | An overhanging mass of snow created by wind, usually near a sharp terrain break such as a ridge. | European Avalanche Warning Services |
| Exposition | Aspects | Direction in which a slope faces as indicated by compass direction of the fall line; i.e. a north slope faces in a northerly direction. | European Avalanche Warning Services |
| Coulée | Sluffs | A small downhill movement of snow. | American Meteorological Society |
| Névé | Firn | Snow accumulated in recent years, mostly atop glaciers, intensely metamorphosed and denser because of melting and refreezing, as well as from pressures of overlying snow masses. | European Avalanche Warning Services |
| Risque | Risk | Likelihood of occurrence combines mathematical probability, risk exposure and possible damages. | European Avalanche Warning Services |
| Plaque | Slab | (Wind Slab; Slab Group) One or more cohesive layers of snow in which the grains are bonded together. A slab initially fails over a broad area, as opposed to a single point. The boundaries of a slab that has failed are the bed surface underneath, the crown at the top, the flanks along the side, and the stauchwall at the bottom. "Slab Group" is sometimes used to refers to a group of snow layers which form a cohesive slab unit above the bed surface in a slab avalanche. "Windslab" denotes one or more slab layers of snow deposited by the wind. Typically the crystals have been broken into small pieces and packed together tightly. | Avalanche Center (US) |
| dur | hard | IACS/UNESCO | |
| faible | low | Snowpack is generally well bonded and stable. Triggering is generally possible only from high additional loads in a few isolated steep extreme terrain features. Only small natural avalanches possible. | European Avalanche Warning Services |
