Chartreuse

Low

Danger level

Low — Generally stable conditions

Triggering is generally possible only from high additional loads in isolated areas of very steep, extreme terrain.

Generally favourable conditions. Evaluate steep extreme terrain carefully.

Stability

DERNIER BULLETIN DE LA SAISON : FIN DE SAISON, PLUS DE NEIGE SUR LE MASSIF La saison est terminée en Chartreuse. Dernier bulletin de la saison, l'équipe de Grenoble vous souhaite un bel été ! A l'année prochaine.

Snow quality

Le massif est sec. Quelques névés sommitaux peuvent subsister localement.

EAWS danger scale

European standard used across avalanche warning services.

1 — Generally stable conditions
Triggering is generally possible only from high additional loads in isolated areas of very steep, extreme terrain.
2 — Heightened avalanche conditions on specific terrain features
Triggering is possible, primarily from high additional loads, particularly on indicated steep slopes.
3 — Dangerous avalanche conditions
Triggering is possible, even from low additional loads, particularly on indicated steep slopes. Large natural avalanches are possible.
4 — Very dangerous avalanche conditions
Triggering is likely, even from low additional loads, on many steep slopes. Large and very large natural avalanches can be expected.
5 — Extraordinary avalanche conditions
Numerous very large and often extremely large natural avalanches can be expected, even in moderately steep terrain.

Avalanche problems

Standard problem types defined by EAWS.

New snow
Instability related to current or recent snowfall. Additional loading onto the existing snowpack is the crucial factor.
Wind slab
Wind-drifted snow forms slabs on leeward slopes, gullies, and behind terrain features.
Persistent weak layers
One or more persistent weak layers in the old snowpack, such as faceted crystals or depth hoar.
Wet snow
Weakening of the snowpack due to liquid water from melt or rain infiltrating the snowpack.
Gliding snow
The entire snowpack glides on smooth ground. Glide cracks may open before release.
Cornices
Overhanging wind-drifted snow on leeward ridgelines. Collapse can trigger avalanches below.
