Risk estimation for Wednesday, April 01, 2026
WINTER SNOWPACK, WITH NUMEROUS WIND SLABS FORMING 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: Wind slabs more numerous at altitude, generally thin but reactive
Stability of the snowpack until Wednesday evening, April 01
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 stormy. These instabilities can be found even far from the ridges / right down to the bottom of slopes and on all aspects, but are generally more numerous on broad South faces. The slabs generally remain small and thin, but can be larger in certain sectors where Monday's snowfall was more significant (notably towards the Ecrins, Promontoire refuge). Slabs are still very reactive in the morning, then the snowpack begins to stabilize in the afternoon as the wind weakens and snow transport stops. Observables: Transport in progress, accumulation, wind-sculpted snow. Natural avalanches: Especially above 2600m, on wind-loaded slopes (generally broad South faces), a few small to medium-sized slab releases remain possible until the end of the wind episode, around midday. In the afternoon, small sluffs are possible under rocks in the sun, especially at low altitude.
Snow quality
Snowpack quality: Snow cover is good at low altitude, and even very good from 1800 / 2000m upwards, 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 faces / under fir trees
Snow quality on Wednesday: Very variable snow quality across the massif. Alternation of wind-hardened / wind-packed snow and scoured zones, revealing very hard / crusted old snow. Some lenses of softer snow are sometimes present (often synonymous with slabs). Ridges and North-facing slopes are often scoured. On South aspects, in some sheltered bowls and at the bottom of slopes / forested sectors, 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 WIND SLABS FORMING LEEWARD AT ALTITUDE The title uses 'Manteau' for snowpack. 'Plaques' (slabs) here refers specifically to wind slabs due to 'sous le vent' (leeward/wind-loaded). |
| 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 gale-force. 'Déclenchements provoqués' is the standard term for human-triggered avalanches. 'Tempétueux' indicates very high wind speeds (gale/storm force). |
| 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 can be found even far from the ridges, extending down to the base of slopes and on all aspects, but are generally more numerous on broad South-facing aspects. 'Bas de pentes' refers to the runout zones or lower sections. 'Large Sud' means the full Southern quadrant (SE to SW). |
| Les plaques restent généralement peu larges et peu épaisses, mais peuvent être de plus grandes tailles sur certains secteurs où les chutes de neige de lundi ont été plus marquées (notamment vers les Ecrins, refuge du Promontoire). | The slabs generally remain narrow and thin, but can be larger in certain sectors where Monday's snowfall was more significant (notably towards the Ecrins, Promontoire refuge). 'Peu larges' and 'peu épaisses' suggest small dimensions, but localized heavy snow ('chutes de neige plus marquées') increases the potential slab size. |
| Les plaques sont encore très réactives le matin, puis le manteau commence à se stabiliser l'après-midi avec l'afaiblissement du vent et l'arrêt du transport de neige. | The slabs are still very reactive in the morning, then the snowpack begins to stabilize in the afternoon as the wind weakens and snow transport stops. 'Réactives' means easy to trigger. 'Transport de neige' refers to wind-driven snow movement. |
| Observables : Transport en cours, accumulation, neige sculptée par le vent. | Observables: Ongoing transport, accumulation, wind-sculpted snow. Field signs skiers should look for: 'neige sculptée' (sastrugi or wind-affected patterns). |
| 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. 'Milieu de journée' is midday/noon. |
| L'après-midi, de petites coulées sont possibles sous les rochers qui prennent le soleil, surtout à basse altitude. | In the afternoon, small loose snow flows are possible under rocks receiving solar radiation, especially at low altitude. 'Coulées' usually implies small, loose snow avalanches (point releases) caused by 'le soleil' (warming). |
| Ciel assez dégagé en matinée, avec quelques nuages près des sommets, sous un vent de Nord-Est encore tempétueux. | Fairly clear sky in the morning, with a few clouds near the summits, under a North-East wind that is still gale-force. 'Dégagé' means clear. 'Sommets' refers to the mountain 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 lighter wind. 'Bourgeonnent' (budding) describes convective cloud growth. |
| Qualification de l’enneigement : L'enneigement est bon à basse altitude, et même très bon dés 1800 / 2000m mais avec des répartitions assez hétérogènes à cause du vent. | Snowpack conditions: Snow coverage is good at low altitude, and even very good from 1800/2000m, but with fairly heterogeneous distribution due to the wind. 'Enneigement' is the general state of snow coverage. 'Hétérogène' refers to the uneven depth caused by wind drifting. |
| Peu de sous couche sous 1700m en plein Sud. | Little underlying snowpack below 1700m on full South aspects. 'Sous couche' (under-layer) refers to the existing base. Below this, skiers might hit ground/rocks. |
| 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 aspects and under fir trees. Identifies where there is enough snow to ski. 'Sapins' (fir trees) often have less snow beneath them due to canopy interception. |
| Qualité de la neige mercredi : Neige de qualité très variable sur le massif. | Snow quality for Wednesday: Very variable snow quality across the massif. 'Massif' refers to the specific mountain range. |
| Alternance de neige durcie / cartonnée par le vent et de zones pelées, faisant ressortir une vieille neige très dure / croûtée. | Alternation of wind-hardened/wind-crusted snow and stripped areas, revealing very hard/crusted old snow. 'Cartonnée' is a specific term for wind-slab/wind-crust that feels like cardboard. 'Pelées' means stripped of snow. |
| Certaines lentilles de neige plus meubles sont parfois présentes (souvent synonyme de plaques). | Some lenses of looser snow are sometimes present (often synonymous with slabs). 'Lentilles' (lenses) are localized deposits of snow. 'Meuble' is loose/unconsolidated snow. |
| Les crêtes et pentes exposées au vent de Nord sont souvent dégarnie. | Ridges and slopes exposed to the North wind are often stripped bare. 'Dégarnie' means the snow has been removed by the wind, exposing ground or old ice. |
| 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 bowls and at the base of slopes/forested sectors, the snow has sometimes remained powdery, with still some good skiing in places. 'Combes' are bowl-shaped 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. |
| 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. |
| tempétueux | gale-force wind | Very strong winds, typically exceeding 60-70 km/h, capable of massive snow transport. |
| neige cartonnée | wind-crusted snow | Snow surface that has been compressed by wind into a stiff, often breakable layer resembling cardboard. |
| zones pelées / dégarnie | stripped slopes | Areas where the wind has removed the recent snow, exposing the old snow surface or the ground. |
| neige meuble | loose snow | Unconsolidated snow that has not yet bonded, often found in sheltered areas or as localized deposits. |
