Risk assessment for Wednesday, April 1, 2026
WINTER SNOWPACK, WITH NUMEROUS WIND SLABS FORMING ON THE LEE SIDE AT ALTITUDE
Risk indices: 5 very high - 4 high - 3 considerable - 2 moderate - 1 low -- In black: the most dangerous slopes
Above 2600m considerable risk index evolving to moderate, lower down moderate index.
Natural avalanches: A few slab releases possible on wind-loaded slopes
Skier-triggered avalanches: More numerous wind slabs at altitude, generally thin but reactive
Stability of the snowpack until Wednesday, April 1 evening
Typical avalanche situation:
Wind slab
Triggered releases: New slabs are still forming this Wednesday under North to North-East winds, especially above 2600m where it is tempestuous. These instabilities are found even far from the ridges / down to the bottom of slopes and on all aspects, but are generally more numerous on a broad South sector. The slabs often remain narrow and thin, but are very reactive during the wind event. In the afternoon, the wind weakens and is no longer strong enough to effectively transport snow and form new instabilities. The slabs formed in the morning gradually stabilize. Observables: Blowing snow, accumulation, wind-sculpted snow. Natural avalanches: Especially above 2600m, on wind-loaded slopes (generally on a broad South sector) a few slab releases of small to medium size remain possible until the end of the wind event, around midday. In the afternoon, small sluffs are possible below rocks in the sun, especially at low altitude.
Snow quality
Snow coverage assessment: Snow conditions are good at low altitude, and even very good from 1800 / 2000m but with fairly heterogeneous distribution due to the wind. Little base below 1700m on full South aspects.
Skiable limits: Around 1000 / 1200m depending on the aspect, with caution on South aspects / under the fir trees
Snow quality Wednesday: Snow of very variable quality across the massif. Alternation of wind-hardened / wind-packed snow and scoured areas, revealing very hard / crusted old snow. Some pockets of looser snow are sometimes present (often synonymous with slabs). Ridges and slopes exposed to the North wind are often bare. On South aspects, in some sheltered bowls and at the bottom of slopes / forested areas, the snow has sometimes remained powdery, with still some good skiing in places.

|---|---|
| MANTEAU HIVERNAL, AVEC DE NOMBREUSES PLAQUES SE FORMANT SOUS LE VENT EN ALTITUDE | WINTER SNOWPACK, WITH NUMEROUS SLABS FORMING LEEWARD AT ALTITUDE The title uses 'manteau hivernal' to indicate cold-season conditions. 'Sous le vent' means 'downwind' or 'leeward'. |
| Déclenchements provoqués : De nouvelles plaques se forment encore ce mercredi sous le vent de Nord à Nord-Est, surtout au-dessus de 2600m où il est tempétueux. | Triggered releases: New slabs are still forming this Wednesday leeward of the North to North-East wind, especially above 2600m where it is storm-force. 'Déclenchements provoqués' refers to human-triggered avalanches. 'Tempétueux' is a strong term for storm-force winds. |
| Ces instabilités se retrouvent même loin des crêtes / jusque dans les bas de pentes et en tout versant, mais sont de manière générale plus nombreuses en large Sud. | These instabilities are found even far from ridges / right down to the bottom of slopes and on all aspects, but are generally more numerous across the broad South. 'Crêtes' means ridges. 'Large Sud' refers to the entire southern arc (SE to SW). |
| Les plaques restent souvent peu larges et peu épaisses, mais sont très réactives pendant l'épisode de vent. | The slabs often remain narrow and thin, but are very reactive during the wind episode. 'Peu larges/épaisses' suggests size 1-2 avalanches. 'Réactive' means they are easy to trigger with a light load. |
| L'après-midi, le vent faiblit et n'est plus suffisamment fort pour transporter efficacement de la neige et former de nouvelles instabilités. | In the afternoon, the wind weakens and is no longer strong enough to effectively transport snow and form new instabilities. 'Faiblit' (weakens) indicates a decreasing trend in wind slab formation. |
| Les plaques formées en matinée se stabilisent progressivement. | The slabs formed in the morning are gradually stabilizing. 'Progressivement' suggests that while the danger is decreasing, it isn't gone immediately. |
| Observables : Transport en cours, accumulation, neige sculptée par le vent. | Observables: Ongoing transport, accumulation, wind-sculpted snow. These are visual cues (clues) for wind-loaded terrain. |
| Départs spontanés : Surtout au-dessus de 2600m, dans les pentes chargées par le vent (généralement en large Sud) quelques ruptures de plaques de tailles petites à moyennes restent possible jusqu'à la fin de l'épisode de vent, autour du milieu de journée. | Natural releases: Especially above 2600m, in wind-loaded slopes (generally broad South) a few slab failures of small to medium sizes remain possible until the end of the wind event, around midday. 'Départs spontanés' are natural avalanches. 'Ruptures de plaques' refers to slab releases. |
| L'après-midi, de petites coulées sont possibles sous les rochers qui prennent le soleil, surtout à basse altitude. | In the afternoon, small sluffs are possible below rocks taking the sun, especially at low altitude. 'Coulées' usually refers to small, loose-snow avalanches (sluffs). 'Prennent le soleil' indicates solar heating. |
| Ciel assez dégagé en matinée, avec quelques nuages près des sommets, sous un vent de Nord-Est encore tempétueux. | Sky quite clear in the morning, with a few clouds near the summits, under a North-East wind that is still storm-force. 'Dégagé' means clear. 'Sommets' are the peaks. |
| L'après-midi les nuages bourgeonnent, accrochant les sommets, sous un vent plus faible. | In the afternoon clouds build up, clinging to the summits, under a weaker wind. 'Bourgeonnent' (literally budding) describes cumulus-type cloud development. |
| L'enneigement est bon à basse altitude, et même très bon dès 1800 / 2000m mais avec des répartitions assez hétérogènes à cause du vent. | Snow coverage is good at low altitude, and even very good from 1800 / 2000m but with quite heterogeneous distribution because of the wind. 'Enneigement' refers to the general state of snow coverage. 'Hétérogène' indicates the wind has moved snow around (drifts and scoured spots). |
| Peu de sous couche sous 1700m en plein Sud. | Little base below 1700m on due South aspects. 'Sous couche' is the existing base of the snowpack. |
| Limites skiables : Vers 1000 / 1200m selon le versant, avec prudence en Sud / sous les sapins | Skiable limits: Around 1000 / 1200m depending on the aspect, with caution on South / under the fir trees 'Sapins' (fir trees) can have thinner snow or hidden obstacles (tree wells). |
| Qualité de la neige mercredi : Neige de qualité très variable sur le massif. | Snow quality Wednesday: Very variable snow quality across the massif. 'Massif' refers to the mountain range/area. |
| Alternance de neige durcie / cartonnée par le vent et de zones pelées, faisant ressortir une vieille neige très dure / croûtée. | Alternation of hardened / wind-pressed snow and scoured zones, revealing a very hard / crusted old snow. 'Cartonnée' (cardboard-like) is the classic term for wind-pressed snow. 'Pelées' (peeled/scoured) means the snow has been blown away down to the old layer. |
| Certaines lentilles de neige plus meubles sont parfois présentes (souvent synonyme de plaques). | Some lenses of softer snow are sometimes present (often synonymous with slabs). 'Meuble' means loose or uncompacted; here it warns that soft-looking snow might actually be a wind slab. |
| Les crêtes et pentes exposées au vent de Nord sont souvent dégarnies. | Ridges and slopes exposed to the North wind are often stripped bare. 'Dégarnies' means the snow cover is sparse or removed. |
| En versants Sud, dans certaines combes abritées et en bas de pentes / secteurs forestiers, la neige est parfois restée poudreuse, avec encore du bon ski par endroits. | On South aspects, in certain sheltered valleys and at the bottom of slopes / forest sectors, the snow has sometimes remained powdery, with good skiing still found in places. 'Combes' are bowl-like valleys. 'Poudreuse' is powder snow. |
| French Term | English Term | Definition |
|---|---|---|
| Risque 3 - Marqué | 3 - 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. |
| Risque 4 - Fort | 4 - High | Snowpack is poorly bonded on most steep slopes. Triggering is likely even from low additional loads on many steep slopes. In some situations, many medium and sometimes large natural avalanches are expected. |
| Indices de risque | Risk Indices | The European Avalanche Danger Scale: 1 (Low) = generally stable; 2 (Moderate) = possible on steep slopes; 3 (Considerable) = triggering possible even by a single skier; 4 (High) = likely even from low loads, natural releases expected; 5 (Very High) = widespread natural avalanches, extremely dangerous. |
| Plaque à vent | Wind slab | A cohesive layer of wind-deposited snow on the lee side of ridges, crests, or obstacles. Often hard or stiff on the surface but resting on a weaker layer beneath. Can be triggered by a single skier. |
| Départ spontané | Natural release | An avalanche that releases without human intervention, triggered by natural factors such as new snowfall, wind loading, warming, or rain. Indicates the snowpack is unstable enough to fail on its own. |
| Déclenchement provoqué | 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. |
| Manteau neigeux | Snowpack | The total accumulation of all snow layers on the ground. Its structure — the arrangement and bonding of different layers — determines avalanche risk. |
| Plaque | Slab | A cohesive layer of snow that can fracture and slide as a unit when a weak layer beneath it collapses. Slabs can be soft or hard, and vary from small to enormous. |
| Rayonnement solaire | Solar radiation | The warming effect of direct sunlight on snow slopes. Solar radiation weakens the snowpack surface, particularly on steep south-facing slopes in spring, increasing wet avalanche risk. |
| sous le vent | leeward | The side sheltered from the wind; where wind-blown snow accumulates to form slabs. |
| crête | ridge | The top edge of a mountain where wind speed increases and snow is transported. |
| pentes chargées par le vent | wind-loaded slopes | Slopes where wind has deposited snow, creating deeper accumulations and potential slabs. |
| coulée | sluff | A small avalanche of loose, unconsolidated snow, often surface-level. |
| neige cartonnée | wind-pressed snow | Snow that has been compacted by the wind into a stiff, often unappealing crust. |
| pelée | scoured | Terrain where the wind has removed the surface snow, often down to the ground or a hard underlying layer. |
| combes abritées | sheltered valleys | Bowl-shaped mountain features or small valleys protected from the wind, where soft snow often remains. |

Limites skiables : Vers 1000 / 1200m selon le versant, avec prudence en Sud / sous les sapins
Qualité de la neige mercredi : Neige de qualité très variable sur le massif. Alternance de neige durcie / cartonnée par le vent et de zones pelées, faisant ressortir une vieille neige très dure / croûtée. Certaines lentilles de neige plus meubles sont parfois présentes (souvent synonyme de plaques). Les crêtes et pentes exposées au vent de Nord sont souvent dégarnie. En versants Sud, dans certaines combes abritées et en bas de pentes / secteurs forestiers, la neige est parfois restée poudreuse, avec encore du bon ski par endroits.
