Risk assessment for Sunday, 26 April 2026
SPRING SNOW COVER, RARE "MELT" AVALANCHE, VERY OCCASIONALLY A LINEAR FRACTURE LINE ON NORTH ASPECTS?
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 avalanche: Rare wet snow avalanches or glide-snow avalanches, mainly on "cold" aspects. A wide fracture line cannot be ruled out on high-altitude North aspects.
Skier-triggered release: Unlikely, or under skis in very wet snow (steep slopes)...
Stability of the snow cover until Sunday, 26 April evening
Typical avalanche situation:
Wet snow
Naturally triggered avalanche: On East, North, and West slopes, where wetting is penetrating deeper, rare wet snow avalanches may occur during the hottest parts of the day or in the evening. Size 1 to 2 with point-release, but exceptionally and mainly on North slopes, a large size 3 avalanche cannot be ruled out if wetting reaches a deeper layer prone to triggering, with a linear fracture and/or glide-snow release possible. On South aspects, less snow and very dense, almost firn, stable... Skier-triggered release: Unlikely, except for a moderate risk of point-release sluffs under skis in steep, well-soaked terrain. Other: Snow sometimes hardened / crusted by refreezing in the shade, especially at the start of the day.
Snow quality
Snow conditions: Snow conditions have decreased significantly over the last 3 weeks, becoming below average on South aspects and at mid-altitudes. They remain decent on high-altitude North slopes.
Skiable limits: Around 1600/1800m on North aspects to 2000/2400m depending on sun aspect, slope steepness...
Snow quality on Sunday: Bumpy snow, sometimes crusted / hardened by refreezing (medium to decent at altitude). Then wetting and melting resume quite quickly in the sun, resulting in very wet snow.

| MANTEAU NEIGEUX PRINTANIER, RARE AVALANCHE DE "FONTE", TRÈS PONCTUELLEMENT UNE CASSURE LINÉAIRE EN FACE NORD ? | SPRING SNOWPACK, RARE "MELT" AVALANCHE, VERY LOCALLY A LINEAR FRACTURE ON NORTH FACE? The title highlights the transition to spring conditions. **Manteau neigeux** is the snowpack. **Fonte** means melt. **Ponctuellement** in avalanche reports means 'locally' or 'in isolated spots'. **Cassure linéaire** refers to a slab fracture (crown line), which is unusual for pure wet snow cycles that usually start from a single point (**départ ponctuel**). |
| Départs spontanés : Dans les pentes Est, Nord et Ouest, où l'humidification gagne en profondeur, de rares avalanches humides peuvent se produire aux heures chaudes de la journée ou le soir. | Spontaneous releases: In East, North, and West slopes, where wetting is gaining depth, rare wet avalanches may occur during the hottest hours of the day or in the evening. **Départs spontanés** are natural (non-human triggered) avalanches. **Humidification** refers to liquid water percolating through the snow. **Gagne en profondeur** means the water is reaching deeper layers, increasing the risk of larger releases. |
| De taille 1 à 2 avec départ ponctuel, mais exceptionnellement et plutôt en versant Nord, une grande avalanche de taille 3 ne peut être exclue si l'humidification atteint une couche fragile plus enfouie, avec départ linéaire et/ou au terrain possible. | Size 1 to 2 with point-release starts, but exceptionally and primarily on North-facing slopes, a large size 3 avalanche cannot be ruled out if the wetting reaches a more deeply buried weak layer, with a linear fracture and/or full-depth release possible. **Taille 1 à 2** refers to the D1-D5 scale (small/medium). **Couche fragile enfouie** means a buried weak layer. **Au terrain** means a full-depth or glide avalanche where the entire snowpack slides off the ground. |
| En faces Sud, moins de neige et très dense, presque de névé, stable... | On South faces, there is less snow and it is very dense, almost like firn (névé), and stable... **Névé** refers to old, compacted, multi-year snow or very dense spring snow that has survived many freeze-thaw cycles. It is usually very stable because it lacks weak layers. |
| Déclenchements provoqués : Peu probables, hormis un risque limité de coulée ponctuelle sous les skis en terrain raide et bien humidifié. | Triggered releases: Unlikely, except for a limited risk of a point-release sluff under skis in steep and well-saturated terrain. **Déclenchements provoqués** are human-triggered avalanches. **Coulée** is often used for a small sluff or slide that is unlikely to bury a person but can knock them off their feet. |
| Autres : Neige parfois durcie / croûtée par le regel à l'ombre, en début de journée notamment. | Other: Snow sometimes hardened / crusted by the overnight refreeze in the shade, particularly at the start of the day. **Regel** is the overnight refreeze, which is the primary stabilizer of spring snow. **À l'ombre** (in the shade) is where the crust stays hard longest, creating a slide hazard for skiers (falling). |
| Soleil parfois voilé. | Sun, sometimes veiled. **Voilé** means the sky is covered by thin high-altitude clouds (cirrus), which can sometimes trap heat (greenhouse effect) and accelerate snow softening even without direct sun. |
| Quelques cumulus isolés l'après-midi. | A few isolated cumulus clouds in the afternoon. Standard afternoon cloud development typical of spring weather. |
| Qualification de l’enneigement : L'enneigement s'est bien réduit depuis 3 semaines, il devient déficitaire en faces Sud et moyenne montagne. | Snow cover assessment: The snowpack has significantly reduced over the last 3 weeks; it is becoming deficient on South faces and in mid-mountain areas. **Déficitaire** means the snow depth is below the historical average for this time of year. **Moyenne montagne** usually refers to elevations between 1500m and 2500m. |
| Il reste correct dans les versants Nord d'altitude. | It remains decent on North-facing slopes at altitude. **Correct** in this context means 'satisfactory' or 'near normal'. |
| Limites skiables : Vers 1600/1800m en Nord à 2000/2400m suivant l'exposition au soleil, la raideur de la pente... | Skiable limits: Around 1600/1800m on North aspects to 2000/2400m depending on sun exposure, slope steepness... This defines the lowest elevation where you can still ski without hitting grass or rocks. |
| Qualité de la neige dimanche : Neige bosselée, parfois croûtée / durcie par le regel (moyen à correct en altitude). | Snow quality Sunday: Bumpy snow, sometimes crusted / hardened by the refreeze (average to decent at altitude). **Bosselée** refers to 'moguls' or 'bumps' created by skier traffic or uneven melting. The quality of the **regel** (refreeze) determines how 'supportive' the crust is for skiing early in the morning. |
| Puis l'humidification et la fonte reprennent, assez rapidement au soleil, donnant une neige très humide. | Then wetting and melting resume quite quickly in the sun, resulting in very wet snow. **Reprennent** means 'resumes' or 'starts again'. In spring, the window of 'good' skiing is between the crust softening and the snow becoming **très humide** (slushy/heavy), which increases avalanche risk. |

|---|---|---|---|
| Départ spontané | Naturally triggered avalanche | Avalanche not caused by external forces, e.g. snowfall or loss in firmness due to weather conditions. | European Avalanche Warning Services |
| déclenchable | 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. | AvalancheClarity Static Glossary |
| Fragile | Prone to triggering | A snowpack or snow layer that tends to release from additional loading. | European Avalanche Warning Services |
| 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 raide | Steep slopes | Slopes steeper than approximately 30°, where most slab avalanches occur. The steeper the slope, the lower the additional load needed to trigger a release. | AvalancheClarity Static Glossary |
| 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 |
| 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 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 |
| mouillée | very wet | IACS/UNESCO | |
| 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 |
| moyen | medium | IACS/UNESCO | |
| très mouillée | soaked | IACS/UNESCO | |
| 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 |
| 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 |
