Risk assessment for Sunday, 26 April 2026
SPRING SNOW COVER - A LITTLE NATURAL WET SNOW ACTIVITY
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Above 2400m, low risk index increasing to moderate, lower down low risk index.
Naturally triggered avalanche: a few wet snow avalanches, generally small - rare large avalanche possible on high-altitude north-facing slopes.
Skier-triggered release: in wet snow under the skis.
Stability of the snow cover until Sunday, 26 April evening
Typical avalanche situation:
Wet snow
Naturally triggered avalanche: after good overnight refreezing, wet snow activity resumes during the day due to heat and sun. A few generally superficial avalanches are then possible from point releases, small in size (size 1). Rare, larger linear releases are possible on northwest to northeast slopes above approximately 2400/2500 m, carrying away the entire snow cover in place. Medium-sized avalanches (size 2), or even very rarely large ones (size 3), when wetting reaches for the first time persistent weak layers buried at the snow base. Skier-triggered release: a skier cutting a steep slope late in the day can initiate a wet snow release under their skis, generally small in size. On high-altitude north-facing slopes above 2400/2500 m, a first superficial wet snow avalanche can, in very rare cases, cause a second larger release in a linear form. The few afternoon showers have little effect on the state of the snow cover across the massif.
Snow quality
Snow conditions are clearly in deficit for the period, with melting continuing at a high rate. Absence of significant precipitation for more than a month and very mild conditions in place since early April.
Snow depth observed: 76 cm at the Nivose de Millefonts at 2430 m, 0 cm at Isola 2000 at 1900 m.
Skiable snow conditions generally from 1900/2000 m on north-facing slopes on favorable terrain (forest roads, grassy terrain) and above 2400 m on south-facing slopes.
Surface snow condition: spring snow cover, crusted in the morning after good overnight refreezing, then rapidly becoming wet during the day on all aspects. Snow can remain hard on steep high-altitude north slopes.

|---|---|
| MANTEAU NEIGEUX PRINTANIER - UN PEU D'ACTIVITÉ NATURELLE EN NEIGE HUMIDE | SPRING SNOWPACK - SOME NATURAL WET SNOW ACTIVITY *Manteau neigeux* means snowpack. *Printanier* (spring-like) indicates the seasonal transition where the snow undergoes melt-freeze cycles. *Neige humide* is the technical term for wet snow. |
| Départs spontanés : après un bon regel nocturne, l'activité en neige humide reprend en cours de journée sous l'effet de la chaleur et du soleil. | Natural avalanches: after a good overnight freeze, wet snow activity resumes during the day under the effect of heat and sun. *Départs spontanés* refers to natural (non-human-triggered) avalanches. *Regel nocturne* (nightly refreeze) is crucial in spring; it stabilizes the snowpack until daytime warming (*chaleur*) melts the bonds again. |
| Quelques avalanches généralement superficielles sont alors possibles par départ ponctuel, de petite taille (taille 1). | Some generally shallow avalanches are possible as point-releases, small in size (size 1). *Superficielles* means only the top layer of snow is moving. *Départ ponctuel* refers to point-release avalanches (loose snow avalanches that start from a single point and fan out), as opposed to slab avalanches. *Taille 1* is the smallest category on the European avalanche size scale. |
| De rares départs linéaires plus volumineux sont possibles dans les pentes nord-ouest à nord-est au-dessus de 2400/2500 m environ, emportant la totalité du manteau neigeux en place. | Rare, larger linear releases are possible on northwest to northeast slopes above approximately 2400/2500 m, carrying away the entire existing snowpack. *Départs linéaires* refers to slab avalanches (where a line/crown breaks). *Emportant la totalité* indicates a full-depth avalanche, where the snow slides all the way to the ground or a very deep interface. |
| Avalanches moyennes (taille 2), voire très rarement grandes (taille 3), quand l'humidification atteint pour la première fois des couches fragiles persistantes enfouies à la base du manteau neigeux. | Medium (size 2) or even very rarely large (size 3) avalanches, when wetting reaches persistent weak layers buried at the base of the snowpack for the first time. *Humidification* is the process of water percolating through the snow. *Couches fragiles persistantes* (Persistent Weak Layers or PWLs) are dangerous because they can collapse and cause large slides. The phrase *pour la première fois* is a major red flag in spring, indicating a "first wetting" event which often triggers deep instabilities. |
| Déclenchements provoqués : un skieur coupant tardivement une pente raide peut initier un départ de neige humide sous ses skis, généralement de petite taille. | Triggered avalanches: a skier cutting a steep slope late in the day can initiate a wet snow release under their skis, generally small in size. *Déclenchements provoqués* means human-triggered avalanches. *Coupant* (cutting/traversing) a slope is a common way to trigger a slide. *Tardivement* (late) emphasizes that the risk increases as the sun warms the snow throughout the day. |
| Dans les ubacs d'altitude au-dessus de 2400/2500 m, une première avalanche superficielle de neige humide peut dans de très rares cas provoquer un seconde départ plus volumineux sous forme linéaire. | On high-altitude shaded slopes above 2400/2500 m, an initial shallow wet snow avalanche can, in very rare cases, trigger a second, larger linear release. *Ubacs* is a classic French alpine term for shaded, north-facing slopes. This sentence describes a "step-down" avalanche, where a small surface slide provides enough force to trigger a deeper, more dangerous slab (*départ linéaire*). |
| Les quelques averses de l'après-midi n'ont que peu d'effet sur l'état du manteau neigeux à l'échelle du massif. | The few afternoon showers have little effect on the state of the snowpack across the mountain range. *Averses* means showers. *Masseif* refers to the specific mountain range/group covered by the bulletin. |
| Beau temps devenant nuageux vers la mi-journée, puis quelques averses l'après-midi par évolution diurne. | Fair weather becoming cloudy around midday, then a few showers in the afternoon due to diurnal evolution. *Évolution diurne* refers to the daily cycle of cloud buildup caused by daytime heating, common in the mountains. |
| Faible risque d'orage isolé. | Low risk of isolated thunderstorms. *Orage* means thunderstorm. *Isolé* means they won't be widespread. |
| Enneigement nettement déficitaire pour la période, avec une fonte qui se poursuit à un rythme élevé. | Snowpack is significantly below average for the period, with melting continuing at a high rate. *Déficitaire* is commonly used in bulletins to mean there is less snow than the historical average. *Fonte* is the noun for melting. |
| Absence de précipitations significatives depuis plus d'un mois et grande douceur en place depuis début avril. | Absence of significant precipitation for over a month and great mildness in place since the beginning of April. *Douceur* (literally "sweetness" or "softness") is the standard French meteorological term for unseasonably warm/mild temperatures. |
| Hauteurs de neige observées : 76 cm à la Nivose de Millefonts à 2430 m, 0 cm à Isola 2000 à 1900 m. | Observed snow depths: 76 cm at the Millefonts Nivose at 2430 m, 0 cm at Isola 2000 at 1900 m. A *Nivose* is an automated high-altitude weather station operated by Météo-France that measures snow depth and other parameters. |
| Enneigement skiable généralement à partir de 1900/2000 m en ubacs sur terrain favorable (routes forestières, terrains herbeux) et plus de 2400 m en adrets. | Skiable snow generally from 1900/2000 m on shaded slopes on favorable terrain (forest roads, grassy areas) and above 2400 m on sunny slopes. *Ubacs* (shaded/North) and *Adrets* (sunny/South) are key topographical terms. Grass (*herbeux*) allows for skiing with less snow depth than rocky terrain. |
| État de la neige en surface : manteau neigeux printanier, croûté le matin après un bon regel nocturne, puis s'humidifiant rapidement en cours de journée dans toutes les expositions. | Surface snow condition: spring snowpack, crusted in the morning after a good overnight freeze, then moistening rapidly during the day across all aspects. *Croûté* (crusted) refers to the hard surface layer formed by freezing. *Expositions* refers to the aspect (direction the slope faces). |
| La neige peut rester dure dans les pentes nord raides de haute altitude. | The snow may remain hard on steep north slopes at high altitude. *Dure* (hard) implies that the sun's energy hasn't been sufficient to melt the morning crust, which can present a sliding fall hazard for skiers. |
| 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 |
| Sous-couche fragile persistante | Persistent weak layers | The persistent weak layers problem is related to the presence of persistent weak layers in the old snowpack. These weak layers typically include buried surface hoar, depth hoar or faceted crystals. Weak layers can persist for weeks to months; possibly most of the winter season. | European Avalanche Warning Services |
| Ubac | North-facing slopes | The shady, north-facing side of a mountain. Snow persists longer and weak layers are better preserved on ubac slopes. | AvalancheClarity Static Glossary |
| 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 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 |
| Couches fragiles | Weak layers | Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail. | 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 |
| Base du manteau neigeux | Snow base | Lowermost layers of the snowpack close to the ground. | 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 |
| 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 | |
| Risque | Risk | Likelihood of occurrence combines mathematical probability, risk exposure and possible damages. | European Avalanche Warning Services |
| 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 |

Estimation des risques pour le dimanche 26 avril 2026
MANTEAU NEIGEUX PRINTANIER - UN PEU D'ACTIVITÉ NATURELLE EN NEIGE HUMIDE
Indices de risque : 5 très fort - 4 fort - 3 marqué - 2 limité - 1 faible -- En noir : les pentes les plus dangereuses
Au-dessus de 2400m indice de risque faible évoluant en limité, plus bas indice faible.
Départs spontanés : quelques avalanches de neige humide, généralement de petite taille - rare avalanche volumineuse possible en ubacs d'altitude.
Déclenchements skieurs : en neige humide sous les skis.
Stabilité du manteau neigeux jusqu'au dimanche 26 avril au soir
Situation avalancheuse typique :Neige humide
Départs spontanés : après un bon regel nocturne, l'activité en neige humide reprend en cours de journée sous l'effet de la chaleur et du soleil. Quelques avalanches généralement superficielles sont alors possibles par départ ponctuel, de petite taille (taille 1). De rares départs linéaires plus volumineux sont possibles dans les pentes nord-ouest à nord-est au-dessus de 2400/2500 m environ, emportant la totalité du manteau neigeux en place. Avalanches moyennes (taille 2), voire très rarement grandes (taille 3), quand l'humidification atteint pour la première fois des couches fragiles persistantes enfouies à la base du manteau neigeux. Déclenchements provoqués : un skieur coupant tardivement une pente raide peut initier un départ de neige humide sous ses skis, généralement de petite taille. Dans les ubacs d'altitude au-dessus de 2400/2500 m, une première avalanche superficielle de neige humide peut dans de très rares cas provoquer un seconde départ plus volumineux sous forme linéaire. Les quelques averses de l'après-midi n'ont que peu d'effet sur l'état du manteau neigeux à l'échelle du massif.
Qualité de la neige
Enneigement nettement déficitaire pour la période, avec une fonte qui se poursuit à un rythme élevé. Absence de précipitations significatives depuis plus d'un mois et grande douceur en place depuis début avril.
Hauteurs de neige observées : 76 cm à la Nivose de Millefonts à 2430 m, 0 cm à Isola 2000 à 1900 m.
Enneigement skiable généralement à partir de 1900/2000 m en ubacs sur terrain favorable (routes forestières, terrains herbeux) et plus de 2400 m en adrets.
État de la neige en surface : manteau neigeux printanier, croûté le matin après un bon regel nocturne, puis s'humidifiant rapidement en cours de journée dans toutes les expositions. La neige peut rester dure dans les pentes nord raides de haute altitude.
