Current Weather Conditions and Severity

The intensity of the snowfall in the Southern French Alps is causing significant concern. Snow accumulation is exceeding 50cm in many areas, particularly in the departments of Hautes-Alpes, Savoie, and Haute-Savoie. These high snowfall totals, combined with extremely low temperatures, are creating hazardous conditions. Wind chill factors are pushing the perceived temperature well below freezing, increasing the risk of hypothermia. Furthermore, the avalanche risk is extremely high in the mountainous regions, including the Écrins Massif and the Vanoise Massif. Blizzard conditions, with strong winds and heavy snow, are being reported in several valleys and passes.

• Snowfall accumulation exceeding 50cm in areas around Briançon, Chamonix, and Grenoble.
• Extremely low temperatures, with wind chill factors reaching -15°C or lower.
• High avalanche risk in the Écrins Massif, Vanoise Massif, and Mercantour National Park.
• Blizzard conditions reported in the Maurienne and Tarentaise valleys.

Travel Disruptions and Safety Precautions

The heavy snowfall has caused widespread travel disruptions throughout Southern France. Numerous road closures are in effect on major routes and mountain passes, including the A43, A51, and many departmental roads. Several ski resorts are experiencing access issues due to road closures and difficult driving conditions. While some airports remain open, significant delays and cancellations are occurring at airports such as Chambéry (CMF) and Grenoble (GNB). Train services are also disrupted, with cancellations and delays affecting lines connecting major cities to the affected areas in the Alps.

Impact on Outdoor Activities and Tourism

The heavy snow has significantly impacted outdoor activities and tourism in Southern France's Alps region. Several popular ski resorts, while striving to remain open, are experiencing operational challenges due to the extreme weather.
