Les Signaraux
5-day forecast, snow depth & avalanche bulletin
Les Signaraux, located at an altitude of 1285 m, with peaks reaching 1417 m, in the Northern French Alps, benefits from specific alpine weather conditions. This page brings together the 9-day weather forecast for Les Signaraux: four days in detail from Météo-France (minimum and maximum temperatures, expected snowfall, 0°C isotherm), then an outlook through day 9, along with the ski area snow depth. The Northern French Alps avalanche bulletin is also available below. Forecasts are calibrated to the resort's actual altitude; the first four days come from Météo-France models (AROME/ARPEGE), the outlook from a longer-range, less precise model.

Forecasts from Météo-France (AROME/ARPEGE models) for the first 4 days, calibrated to the exact resort altitude. The 0°C isotherm is given as a range (min/max over the day) to honestly reflect its variation throughout the day.
Longer-range outlook (ECMWF European model): indicative only, less reliable at this range, and not included in the snowfall total.

Hourly temperature & 0°C isotherm
9-day snowfall forecast
Cumulative forecast: 0 cm at the resort base (1,285 m) and 0 cm at the summit (1,417 m) over the next 4 days (Météo-France forecast). For the following days, the outlook is given as a range and is not included in this total.
Snow line over the coming days in Les Signaraux
No snow forecast on the ski area over the next 4 days: the chart shows the snow line altitude during precipitation.
Snow line: the altitude above which precipitation falls as snow. It is computed hour by hour, during precipitation, from Météo-France temperature and humidity at altitude: it is the altitude where the wet-bulb temperature rises above 1.3°C (the same definition as the German weather service's snowfall line). Météo-France days only, not the longer-range outlook.

Snow quality
Au-dessus de 2900m indice de risque limité, plus bas indice faible.
Stability: MANTEAU INSTABLE EN ALTITUDE DANS LA COUCHE DE NEIGE RECENTE, PARFOIS TRAVAILLEE PAR LE VENT
Déclenchements provoqués : En toute orientation au-dessus de 2900 / 3000m, les 30 à 50cm de neige récente hébergent parfois encore quelques instabilités. Si le manteau est en cours de stabilisation, le passage d'une personne peut encore suffir à déclencher une avalanche, avec des cassures pouvant être supérieures à 50cm dans les accumulations formées par le vent de Nord de vendredi. Dans un large secteur Nord au-dessus de 3200m, des grains anguleux ont pu se former dans la couche de neige datant d'octobre, rendant le manteau un peu plus sensible, et pouvant favoriser des cassures plus larges. Plus bas que 2900 / 3000m, la couche de neige diminue rapidement, et le risque d'avalanche devient faible et se cantonne uniquement aux versants ombragés. Départs spontanés : Peu probables. Autre : Sur les glaciers, les crevasses sont parfois encore ouvertes ou a peine cachées par la couche de neige récente.
