Risk assessment for Sunday, 26 April 2026
DEEP WETTING STILL ONGOING.
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Considerable risk level.
Naturally triggered avalanche: in wet snow, medium-sized to rarely very large full depth slab avalanches.
Skier-triggered release: in wet snow only.
Stability of the snow cover until Sunday, 26 April evening
Typical avalanche situation: 
Wet snow
Full depth slab avalanches
Naturally triggered avalanche: sluff and small to medium-sized avalanches in wet snow, rarely large. Snow cover barely refrozen below 2400m, weakly frozen on the surface above in the early morning, so little activity to be expected during the first hours of the day, mostly in the form of occasional point releases of snowballs and wet snow sluff. Activity increasing in frequency under morning clearings then afternoon showers, sluffs will become medium-sized avalanches on steep slopes. As wetting penetrates deep into the snow cover with daytime changes, a few medium-sized full depth slab avalanches remain possible in the afternoon and at the end of the day on north slopes, starting from the top of the massif, locally causing a large avalanche by a cascade effect carrying away the slush below that can descend to low altitudes. Rarer but still possible during this same time of day, a very large full depth slab avalanche can trigger spontaneously, particularly at the level of fissures, open or opening mostly above 2400 to 2500m now, where significant snow dunes for the season are still found around the northern sector. Skier-triggered release: in wet snow only. Difficult triggering of snowballs and small surface sluff on northeast to east slopes in the early morning, then easy triggering of sluff and small avalanches by a single skier or hiker when cutting a steep slope in very wet snow to slush, very locally a medium avalanche at the peak of wetting in south to west sectors. Others: - cornice and snow bridges still in place are fragile and weak, potentially collapsing spontaneously in the morning or under the weight of a single person. - hiking trails already clear of snow but located below high-altitude sectors still loaded with snow can be reached by a large full depth slab avalanche or larger in the afternoon.
Snow quality
Snow conditions: rather good for the season and still starting around 1800m in the north and above 2100m in the south. These snow limits are gradually rising in the ambient mildness, under morning clearings and a few afternoon showers.
Snow state: in the early morning, snow cover barely refrozen below 2400m but supporting weight, more or less frozen on the surface above.
In the ambient mildness, under morning clearings and locally thundery afternoon showers, deep wetting continues, the snow cover softens over the hours: snow becoming very wet to slush on north slopes above 2400/2500m, often rotten on north slopes below 2400/2500m and on steep south slopes.

|---|---|
| HUMIDIFICATION EN PROFONDEUR TOUJOURS EN COURS. | DEEP WETTING STILL IN PROGRESS. *Humidification en profondeur* refers to water penetrating through the entire snowpack, not just the surface. *En cours* means ongoing or in progress. |
| Départs spontanés : coulées et avalanches petites à moyennes en neige humide, rarement grandes. | Spontaneous releases: small to medium wet snow slides and avalanches, rarely large. *Départs spontanés* are natural avalanches. *Coulées* are small slides or sluffs. *Neige humide* is wet snow. |
| Manteau neigeux à peine ressaisi sous 2400m, faiblement regelé en surface au-dessus au petit matin, donc peu d'activité à attendre aux premières heures de la journée, plutôt sous forme de départs ponctuels de boulettes et de coulées de neige humide. | Snowpack barely firmed up below 2400m, weakly refrozen on the surface above in the early morning; therefore, little activity is expected in the early hours of the day, mostly in the form of point-release pinwheels and wet snow slides. *Ressaisi* describes snow that has firmed up due to cooling but hasn't necessarily frozen hard. *Regelé* means refrozen. *Boulettes* are pinwheels or rollers, typical signs of surface warming. |
| Activité augmentant en fréquence sous les éclaircies du matin puis les averses de l'après-midi, les coulées deviendront des avalanches de taille moyenne dans les pentes raides. | Activity increasing in frequency during morning sunny spells and then afternoon showers; slides will become medium-sized avalanches on steep slopes. *Éclaircies* are sunny spells or clearings in the cloud cover. *Averses* means showers. |
| L'humidification pénétrant en profondeur dans le manteau neigeux au cours de la journée, quelques avalanches de fond de taille moyenne restent possibles dans l'après-midi et en fin de journée dans les pentes nord, partant du haut du massif, engendrant localement par effet de cascade en emportant la neige détrempée en contrebas une avalanche de grande taille pouvant descendre bas en altitude. | As wetting penetrates deep into the snowpack during the day, a few medium-sized full-depth (glide) avalanches remain possible in the afternoon and late evening on north-facing slopes, starting from the high parts of the massif, locally creating a large avalanche via a cascade effect by carrying away the water-saturated snow below, which can descend to low altitudes. *Avalanche de fond* is a full-depth or glide avalanche. *Effet de cascade* refers to an avalanche triggering more snow as it moves down. *Détrempée* means water-saturated/soaked (more severe than *humide*). |
| Plus rare mais toujours possible à cette même période de la journée, une très grande avalanche de fond peut spontanément se déclencher, notamment au niveau des fissures, ouvertes ou s'ouvrant plutôt au-dessus de 2400 à 2500m maintenant, où l'on trouve autour du secteur nord des accumulations encore importantes pour la saison. | Rarer but still possible during the same period of the day, a very large full-depth avalanche may trigger spontaneously, particularly at the level of glide cracks, either already open or opening, mainly above 2400 to 2500m now, where snow accumulations in northern sectors remain significant for the season. *Fissures* (or *fissures de reptation*) refers to glide cracks, a classic warning sign of full-depth avalanche risk. |
| Déclenchements provoqués : en neige humide seulement. | Triggered releases: in wet snow only. *Déclenchements provoqués* refer to human-triggered avalanches. |
| Déclenchement difficile de boulettes et de petites coulées de surface en pentes nord-est à est en début de matinée, puis déclenchement aisé de coulées et petites avalanches par un seul skieur ou randonneur en coupant une pente raide en neige très humide à détrempée, très localement une avalanche moyenne au plus fort d' l'humidification dans les secteurs sud à ouest. | Difficult to trigger pinwheels and small surface slides on northeast to east slopes in the early morning, followed by easy triggering of slides and small avalanches by a single skier or hiker when cutting a steep slope in very wet to water-saturated snow; very locally, a medium avalanche is possible at the peak of wetting in south to west sectors. *Coupant une pente* means cutting across or traversing a slope. *Plus fort de l'humidification* means the peak of the daily heating/wetting cycle. |
| Autres : | Others: Miscellaneous hazards. |
| corniches et ponts de neige encore en place fragiles et peu résistants, pouvant céder dès le matin spontanément ou sous le poids d'une seule personne. | cornices and snow bridges still in place are fragile and have little strength, capable of collapsing as early as the morning spontaneously or under the weight of a single person. *Corniches* (overhanging snow) and *ponts de neige* (snow bridges over crevasses or streams) are high-risk features in the spring thaw. |
| les chemins de randonnée déjà déneigés mais situés sous les secteurs d'altitude encore chargés peuvent être atteints par une avalanche de fond de grande taille ou plus dans l'après-midi. | hiking trails already clear of snow but located below high-altitude sectors that are still loaded can be hit by a large or even larger full-depth avalanche in the afternoon. A warning for hikers: even if the ground under your feet is clear (*déneigé*), you may be in the runout zone of high-altitude snow (*secteurs chargés*). |
| Temps doux, mer de nuages au petit matin, sec avec éclaircies en matinée, averses localement orageuses l'après-midi. | Mild weather, sea of clouds in the early morning, dry with sunny spells in the morning, locally thundery showers in the afternoon. *Mer de nuages* is a sea of clouds. *Orageuses* indicates potential for thunderstorms, which often bring heavy precipitation that rapidly destabilizes wet snow. |
| Enneigement : plutôt bon pour la saison et débutant encore vers 1800m en nord et au-dessus de 2100m en sud. | Snow cover: rather good for the season and still starting around 1800m on north slopes and above 2100m on south slopes. *Enneigement* refers to the general snow conditions or quantity. *Nord/Sud* refers to the aspect of the slopes. |
| Les limites de cet enneigement remontent progressivement dans la douceur ambiante, sous les éclaircies matinales et les quelques averses de l'après-midi. | These snow limits are gradually rising in the mild ambient air, under morning sunny spells and a few afternoon showers. *Remontent* means the snow line is moving higher up the mountain as snow melts at lower elevations. |
| État de la neige : au petit matin, manteau neigeux tout juste ressaisi sous 2400m mais portant, plus au moins regelé en surface au dessus. | Snow condition: in the early morning, the snowpack has just barely firmed up below 2400m but is supportive, and is more or less refrozen on the surface above. *Portant* means the snow surface can support the weight of a person (it's 'supportive'). |
| Dans la douceur ambiante, sous les éclaircies du matin, les averses localement orageuses de l'après-midi, l'humidification en profondeur se poursuit, le manteau neigeux ramollit au fil des heures : neige devenant très humide à détrempée en versants nord au-dessus de 2400/2500m, souvent pourrie en versants nord sous 2400/2500m et en versants sud raides. | In the mild ambient air, under the morning sunny spells and locally thundery afternoon showers, deep wetting continues and the snowpack softens as the hours pass: snow becoming very wet to water-saturated on north slopes above 2400/2500m, often rotten on north slopes below 2400/2500m and on steep south slopes. *Neige pourrie* (rotten snow) is a term for loose, unbonded, water-saturated crystals that provide no structural strength. |

|---|---|---|---|
| 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 |
| Avalanche de fond | Full depth slab avalanches | An avalanche which glides over the ground, across firn snow or atop a glacier in the fracture zone, sweeping the entire season’s snowpack with it. | 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 |
| Au cours de la journée | Daytime changes | Evolving avalanche danger over the course of a day. Avalanche danger can vary greatly during the day. Springtime situations are typical: after a clear night, avalanche danger is low early in the morning, then increases over the course of the day due to daytime warming and solar radiation. Also common while heavy snowfall, prolonged wind activity and rain. | 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 |
| Avalanche de plaque | Slab avalanches | The abrupt release of a slab of snow on a mountain slope. | European Avalanche Warning Services |
| 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 |
| 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 |
| Accumulations | Snow dunes | Snow deposits formed by wind-transported snow. Ripples are small transversal depositional features. Dunes are typically larger in scale and often Barchanoid. | 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 |

| moyen | medium | IACS/UNESCO | |
| Coulée | Sluffs | A small downhill movement of snow. | American Meteorological Society |
| Neige détrempée | Slush | Separated rounded particles completely immersed in water (liquid water content > 15% (volume fraction)). | 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 |

Stabilité du manteau neigeux jusqu'au dimanche 26 avril au soir
Situation avalancheuse typique :Neige humideAvalanches de fond
Départs spontanés : coulées et avalanches petites à moyennes en neige humide, rarement grandes. Manteau neigeux à peine ressaisi sous 2400m, faiblement regelé en surface au-dessus au petit matin, donc peu d'activité à attendre aux premières heures de la journée, plutôt sous forme de départs ponctuels de boulettes et de coulées de neige humide.

Plus rare mais toujours possible à cette même période de la journée, une très grande avalanche de fond peut spontanément se déclencher, notamment au niveau des fissures, ouvertes ou s'ouvrant plutôt au-dessus de 2400 à 2500m maintenant, où l'on trouve autour du secteur nord des accumulations encore importantes pour la saison. Déclenchements provoqués : en neige humide seulement. Déclenchement difficile de boulettes et de petites coulées de surface en pentes nord-est à est en début de matinée, puis déclenchement aisé de coulées et petites avalanches par un seul skieur ou randonneur en coupant une pente raide en neige très humide à détrempée, très localement une avalanche moyenne au plus fort d' l'humidification dans les secteurs sud à ouest. Autres : - corniches et ponts de neige encore en place fragiles et peu résistants, pouvant céder dès le matin spontanément ou sous le poids d'une seule personne. - les chemins de randonnée déjà déneigés mais situés sous les secteurs d'altitude encore chargés peuvent être atteints par une avalanche de fond de grande taille ou plus dans l'après-midi.
Qualité de la neige
Enneigement : plutôt bon pour la saison et débutant encore vers 1800m en nord et au-dessus de 2100m en sud. Les limites de cet enneigement remontent progressivement dans la douceur ambiante, sous les éclaircies matinales et les quelques averses de l'après-midi.
État de la neige : au petit matin, manteau neigeux tout juste ressaisi sous 2400m mais portant, plus au moins regelé en surface au dessus.
Dans la douceur ambiante, sous les éclaircies du matin, les averses localement orageuses de l'après-midi, l'humidification en profondeur se poursuit, le manteau neigeux ramollit au fil des heures : neige devenant très humide à détrempée en versants nord au-dessus de 2400/2500m, souvent pourrie en versants nord sous 2400/2500m et en versants sud raides.
