Pick an altitude and a period: the map and table show the fresh snow expected in each of the twelve massifs of Savoie, Haute-Savoie and northern Isère, with the lowest forecast rain-snow line.
In short. For each snow massif of the Northern French Alps, this page gives the snowfall total forecast by the Open-Meteo model over the next 24, 48 and 72 hours at 1,500, 2,000 and 2,500 m, recalculated every hour. These are estimates at a representative point of each massif, not measurements or an avalanche bulletin.

Each marker sits in the heart of a massif and shows, in centimetres, the fresh snow the model forecasts at the chosen altitude over the chosen period. The table gives the three altitudes side by side, a day-by-day breakdown and the lowest rain-snow line of the period. Massifs are sorted from the snowiest to the least snowy.
In the mountains a few hundred metres change everything: the same shower can fall as rain at 1,500 m and as snow at 2,500 m. Comparing the three columns shows where the snow line sits and which resorts or routes are affected. The Bauges and Chartreuse top out below 2,500 m, so their highest column stays empty.
A forecast snowfall total is not the snow depth on the ground: snow settles, melts or is moved by the wind. For measured depths, see Météo-France observation posts; for avalanche risk, only Météo-France’s avalanche risk bulletin (BRA) is authoritative.
Observed snow, post by postOne point per massif, queried at each altitude in a single request to the Open-Meteo model. The snow for each hour is the higher of the model’s snowfall and the precipitation falling at sub-zero or near-zero temperatures (1 mm of water for 0.7 cm of snow), as everywhere on the site. Totals are recalculated every hour.
Sources and methodologyAccording to the Open-Meteo model read on 7 October at 21:02, at 2,000 m the highest totals over the next 48 hours are expected in Chartreuse (22 cm), Belledonne (11 cm), Bauges (6 cm); the lowest rain-snow line of the period is around 1,550 m. These are model estimates, recalculated every hour, not measurements.
No. They are Open-Meteo model forecasts at a representative point of each massif, at the stated altitude. Actual amounts vary with aspect, terrain and wind.
The Bauges and Chartreuse top out below 2,500 m: Savoie Snow does not show a forecast for an altitude the massif does not reach.
No. Before any trip into snowy mountains, check Météo-France’s avalanche risk bulletin for the massif concerned.

Open-Meteo model estimates for a representative point of each massif, at the stated altitude; they are neither measurements nor a bulletin. Forecast snowfall is not the snow depth on the ground. The rain-snow line comes from the lowest freezing level of the period. On the map, a massif lower than the chosen altitude (Bauges, Chartreuse, Chablais at 2,500 m) shows the total at its highest computed altitude, with a dotted outline. “—”: missing data.
