Major Snowstorm Closes Ski Resorts and Transport Routes in Swiss Alps

Late-Season Snowstorm Disrupts Swiss Alps

A significant late-season snowstorm has hit southern Switzerland and northern Italy, causing widespread disruptions. The storm has forced the closure of ski resorts, cut off mountain towns, and raised avalanche risks to their highest levels. Heavy snowfall and rain have led to the shutdown of major transport routes, leaving several communities isolated and without power.

The storm's impact has been severe, with over a metre of new snow reported in parts of Valais. Authorities have closed crucial road and rail connections, including the Simplon Pass and Grand St-Bernard Pass linking Switzerland and Italy. Towns like Zermatt, Simplon Dorf, and Gondo have become inaccessible, with rail services suspended and replacement buses unable to reach them.

The avalanche risk has been raised to level 5 - the maximum - across several regions including Upper Valais, Saas Valley, and the Simplon region. The Swiss Institute for Snow and Avalanche Research has warned of the potential for numerous large avalanches at higher altitudes and wet snow avalanches at lower elevations. Flooding alerts have also been issued for the Rhône and its tributaries, with warnings of rising water levels, debris flows, and landslides.

The storm's timing coincides with the start of the Easter holiday period, traditionally a busy time for travel through the Alps. Most ski resorts in the affected areas have been forced to close due to the extreme weather conditions and high avalanche risk. Some resorts reported up to 75 centimetres of fresh snow in a single day.

Local authorities have urged residents and travellers to exercise extreme caution, avoid unnecessary travel, and stay away from potential hazards such as trees and watercourses. Emergency services are working to clear roads and restore essential services, but the ongoing precipitation is expected to cause further disruptions. Skiers and riders planning trips to the region should check local conditions and resort status before travelling, as the situation remains dynamic.
