It’s important to acknowledge that different weather influences can impact snow conditions across mountain regions. For instance, in the northwestern Alps (cluster 6 and 8), weather plays a significant role in shaping snow conditions and skiing experiences. The region is more susceptible to the warming influences of the Atlantic Gulf stream resulting in increased precipitation and a heightened risk of rain at lower-altitude ski resorts. Moreover, its complex topography create a diverse weather landscape, impacting snowfall patterns and temperatures across various ski resorts. During the winter season, prevailing weather systems from the west and northwest bring the bulk of snowfall to the northwestern Alps. While western winds ensure widespread snow coverage, northwesterly winds may struggle to reach certain areas, influencing the distribution of snow across the region. Additionally, the northern Alps experience occasional weather anomalies, such as Föhn winds or retour d’est events. Föhn winds, originating from the southwest, can bring mild temperatures and precipitation to higher elevations, affecting snow quality and ski conditions. In contrast, retour d’est events, characterized by easterly or south-easterly airflows, favor specific areas like Haute Maurienne, the far south-east of the Savoie and eastern Vanoise with enhanced snowfall, offering opportunities for exceptional powder days.

Resorts nestled within the southwestern Alps (Cluster 3) exhibit notable fluctuations in snowfall patterns due to their close proximity to the Mediterranean Sea. This geographic adjacency engenders a nuanced interplay of atmospheric dynamics, profoundly shaping snow accumulation and skiing conditions across the region. The influence of the Mediterranean imparts distinct characteristics to the winter climate, often resulting in varied snowfall throughout the season. The most significant snowfalls are generated when the weather comes from between the west and south. The one major exception is the border areas of the far south-east of the French Alps, like Isola 2000, which get their biggest snowfalls from the east or south-east in a retour d’est. With mild maritime air masses periodically affecting the area, temperatures tend to be moderated, albeit with occasional deviations. Consequently, snow conditions may become less predictable, with instances of rain occurring at lower elevations and wetter, heavier snow at higher altitudes, impacting the skiing experience for visitors. However, despite the inherent variability influenced by Mediterranean proximity, the southwestern Alps boast resilience and advantageous snowfall dynamics. During episodes of cold fronts or intense storms fueled by moisture-laden air masses from the Mediterranean, the region experiences substantial snowfall.

In the eastern sector of the Southern Alps (Cluster 7), which encompasses areas like the Dolomites, weather dynamics are influenced by a complex interplay of geographical and climatic factors. Proximity to the Mediterranean Sea introduces variability in weather patterns, with the Genoa Low serving as a significant atmospheric feature driving moisture-laden air masses into the region. Despite this, recent years have witnessed prolonged periods characterized by diminished snowfall, presenting challenges to the ski industry in the area. This variability in precipitation, coupled with fluctuations in temperature and atmospheric pressure, contributes to a dynamic snowfall regime and variable skiing conditions in the Eastern Southern Alps.
