Risk assessment for Sunday, 26 April 2026
VERY DENSE SNOW COVER, STABLE..
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Risk index low.
Naturally triggered avalanche: Unlikely.
Skier-triggered release: Unlikely. Watch out in the morning for surfaces hardened by refreezing.
Stability of the snow cover until Sunday, 26 April evening
Typical avalanche situation:
No predominant avalanche situation
Less and less snow in place and very dense, almost like firn, so stable even when it is wet during the day... Naturally triggered avalanche: Unlikely, or a very rare wet sluff on a very steep slope. Note also a bit of overnight refreezing possible Sunday morning. Skier-triggered release: Unlikely, or very rarely under skis in wet snow on a warmed slope. Others: Surfaces temporarily hardened in case of overnight refreezing, which can be slippery.
Snow quality
Snow conditions: Snow cover has been greatly reduced over the last 3 weeks and is becoming below average for the season. In the South only rare firn remains... the end of the season is approaching.
Skiable limits: Around 1500 to 2000m depending on the aspect, the steepness of the slope...
Snow quality Sunday: Spring snow cover. Medium to decent overnight refreezing. During the day, humidification and melting resume. Very wet snow, but dense.

| French | Translation & Notes |
|---|---|
| MANTEAU NEIGEUX TRES DENSE, STABLE.. | VERY DENSE SNOWPACK, STABLE.. *Manteau neigeux* is the standard term for 'snowpack'. *Dense* indicates the snow has settled and compacted, usually increasing stability. |
| De moins en moins de neige en place et très dense, presque de névé, donc stable même lorsqu'elle est humide en journée... | Less and less snow on the ground, and very dense, almost like firn, therefore stable even when it becomes wet during the day... *Névé* refers to firn or a patch of old, perennial snow. It implies a very high density that resists typical wet-snow avalanches. *Humide* means wet/moist, often a result of solar radiation or high temperatures. |
| Départs spontanés : Peu probables, ou très rare coulée humide en pente bien raide. | Spontaneous releases: Unlikely, or very rare wet snow slides on very steep slopes. *Départs spontanés* are avalanches that occur without human triggers. A *coulée* is a small slide or sluff, usually less dangerous than a full-scale avalanche but still a hazard. |
| Noter aussi un peu de regel nocturne possible dimanche matin. | Note also a slight overnight refreeze possible Sunday morning. *Regel nocturne* is the 'overnight refreeze'. This is a critical safety factor in spring; it stabilizes the snowpack and creates a hard surface. |
| Déclenchements provoqués : Peu probables, ou de manière très rare sous les skis en neige humide dans une pente réchauffée. | Triggered releases: Unlikely, or very rarely under skis in wet snow on a warmed slope. *Déclenchements provoqués* refers to human-triggered avalanches. *Pente réchauffée* refers to a 'warmed slope', where solar heat has weakened the snow bonds. |
| Autres : Surfaces temporairement durcies en cas de regel nocturne, pouvant être glissantes. | Others: Surfaces temporarily hardened in case of an overnight refreeze, which may be slippery. *Durcies* means hardened. This warning highlights a non-avalanche hazard: the danger of a 'slide for life' on icy, frozen spring snow. |
| Indice de risque faible. | Low risk index. *Indice de risque* is the risk level. *Faible* is Level 1 on the 5-point European scale. |
| Soleil parfois voilé. | Sun, sometimes hazy. *Voilé* (literally 'veiled') means thin high clouds are filtering the sunlight, which can still allow significant solar radiation to reach the snow. |
| Quelques cumulus isolés l'après-midi. | Some isolated cumulus clouds in the afternoon. *Cumulus* clouds are the puffy, cotton-like clouds often associated with daytime heating. |
| Qualification de l’enneigement : L'enneigement s'est fortement réduit depuis 3 semaines et devient déficitaire pour la saison. | Snowpack evaluation: Snow cover has decreased significantly over the last 3 weeks and is becoming below average for the season. *Déficitaire* means there is less snow than the historical average for this time of year. |
| Au Sud il ne reste plus que de rares névés... la fin de saison approche. | To the South, only rare firn patches remain... the end of the season is approaching. *Au Sud* refers to south-facing aspects (sunny slopes). *Rares névés* suggests the ground is mostly bare. |
| Limites skiables : Vers 1500 à 2000m environ suivant l'exposition, la raideur de la pente... | Skiable limits: Around 1500 to 2000m depending on aspect, slope steepness... *Exposition* refers to the aspect (N, S, E, W). *Raideur* is the steepness. |
| Qualité de la neige dimanche : Manteau neigeux printanier. | Snow quality on Sunday: Spring snowpack. *Printanier* (spring-like) describes a snowpack undergoing freeze-thaw cycles. |
| Regel nocturne moyen à correct. | Average to good overnight refreeze. *Moyen à correct* suggests the crust will be strong enough to support a person's weight in the morning but might melt quickly. |
| En journée reprise de l'humidification et de la fonte. | During the day, humidification and melting will resume. *Humidification* is the process of liquid water percolating through the snow. *Fonte* is the melting of the surface. |
| Neige très humide, mais dense. | Very wet snow, but dense. While *humide* snow is often unstable, the *dense* nature of this specific snowpack (old, settled snow) suggests it maintains structural integrity. |
| French Term | English Term | Definition | Source |
|---|---|---|---|
| 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 |
| 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 slope | 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 |
| Très pentu | Very steep | Quite unfavourable slope with regard to angle (steeper than 40 degrees), terrain profile, proximity to ridge, smoothness of underlying ground surface. | 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 | Aspect | 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 | |
| Coulée | Sluff | 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 |
