Winter will start with a bang! Heavy snowfalls in the Alps and Pyrenees

From Sunday 8 December, the French and Italian Alps will receive the first significant snowfalls of the season thanks to a strong push of polar air from Scandinavia towards the Mediterranean. This phenomenon will also lead to a significant drop in temperatures in the Pyrenees, between 2 and 3 degrees below seasonal averages, and precipitation in the form of snow that will affect even the lower altitudes, with the snow line dropping to 500-900 metres depending on the area.

Lower temperatures and snowfall in the Alps

Ski resorts such as Chamonix-Mont-Blanc, Val-d’Isère, Tignes and Les Deux Alpes will be among the biggest beneficiaries, with significant snow accumulations starting on Sunday and extending over several days next week. At altitudes of 1,800 metres, snow depths of up to one metre are forecast, while at higher altitudes, such as 2,000 metres, there could be up to 1.5 metres of fresh snow.

The cold front is also expected to affect the Italian Alps, bringing heavy snowfalls to some of Italy’s best ski resorts. Resorts such as Livigno, Cortina d’Ampezzo, Madonna di Campiglio and Breuil-Cervinia will benefit from these weather conditions. In Livigno, snowfall is expected to begin on Sunday, with maximum temperatures of around -5°C and minimum temperatures of -15°C, and to continue throughout the week, improving conditions for skiers. Similarly, Cortina d’Ampezzo and Madonna di Campiglio will experience cold temperatures and snowfalls that will contribute to a sufficient depth of snow for skiing. In Breuil-Cervinia, periods of snow are also forecast from Sunday, with maximum temperatures of -7°C and minimum temperatures of -13°C, which will favour the accumulation of snow on the slopes.

These wintry conditions will create a solid snow base in the resorts of the French, Italian and Swiss Alps, bringing the first generous, high-quality snowfalls to the slopes of the Alps.

The drop in temperatures and the arrival of humid air will encourage sustained snowfalls and, in some areas, snowstorms that will make road access to villages and mid-mountain resorts difficult. These unfavourable conditions will also increase the risk of avalanches, particularly in areas where the snowpack is unstable. It is therefore advisable to take extreme precautions and to follow the instructions of the local safety and meteorological services.

Perfect storm in the French and Spanish Pyrenees

In the Pyrenees, temperatures are expected to fall significantly, with highs around 7°C and lows close to -1°C. Precipitation in the form of snow is expected at altitudes above 900 metres, particularly on Saturday night. These conditions could generate significant snow accumulations, improving conditions for winter activities in the region.

The arrival of the cold front will affect the French and Spanish Pyrenees, causing a significant drop in temperatures and precipitation in the form of snow at relatively low altitudes. According to the weather forecasts, snow cover could drop to 500-900 metres, depending on the area, which will benefit several ski resorts in the region.

In the French Pyrenees, the more easterly resorts such as Font-Romeu and Les Angles will benefit from this polar front, as will the more westerly resorts of Peyragudes, Saint-Lary and Piau Engaly, which will be the most favoured by these conditions. Snowfall is expected to start on Sunday, with highs around -2°C and lows of -5°C, and to continue throughout the week, improving conditions for skiers.

In the Spanish Pyrenees, resorts such as Baqueira Beret, Formigal and Cerler will also receive heavy snowfalls. In Baqueira, for example, snow is expected from the early hours of Saturday to Sunday, with maximum temperatures of 0°C and minimum temperatures of -5°C, which will allow a snowpack to build up that will be ideal for skiing in the near future.

Warming likely to resume in mid-December

For the rest of the week, a cold and unstable environment will persist, with further precipitation and strong winds in the high mountains. This situation could persist until Wednesday, when the intensity of the snowfall will gradually diminish. However, the long-range forecasts point to a possible thermal recovery in mid-December, which could guarantee lasting winter conditions both in the ski areas of the Alps and in the ski resorts of the French and Spanish Pyrenees.

With this data, all the signs are that the resorts with slopes at altitude will be consolidated as the safest options for enjoying the snow over the coming days. Similarly, the snowfall could be the definitive boost for the full start of the season in the lower altitude resorts, where the snowfall expected from 900 metres upwards will guarantee sufficient depth to open the ski resorts based at lower altitudes.

Given the variability of weather conditions and the possibility of snowfall at medium and high altitudes, the public and travellers are advised to consult official weather reports and take the necessary precautions when travelling in the affected areas. In addition, local authorities and emergency services are advised to be prepared to respond to possible winter-related incidents.
