As the long drought comes to an end, Meteo Schweiz is forecasting heavy rainfall for the southern side of the Alps in the coming days. A robust southern to southeastern upper-level flow, combined with a low-pressure system over the Gulf of Genoa, is expected to bring significant moisture to the region, particularly on Wednesday, April 16, and Thursday, April 17, 2025. This weather pattern is likely to result in extreme precipitation amounts.
The southeastern Valais and western Ticino are anticipated to be the most affected areas, with a heightened risk of floods and landslides. The snow line is expected to be between 1500 m and 2000 m, meaning that some precipitation will fall as snow, temporarily delaying runoff into waterways.
Travelers considering a Mediterranean getaway during the Easter holiday might want to rethink their plans, as meteorologists are warning of severe storms threatening popular vacation regions, particularly in Italy. These storms could lead to life-threatening conditions, including heavy rainfall that may flood roads and isolate entire villages.
Recent weeks have already seen severe weather in Tuscany, with reports of flooding in Sicily. Northern Italy is predicted to bear the brunt of the upcoming storms, especially in the Aosta Valley. Meteorologist Dominik Jung has warned of potentially catastrophic rainfall, forecasting up to 300 liters in some areas. In addition, the southern part of Switzerland and southeastern France are also expected to experience significant rainfall, with some regions in the Balkans anticipating up to 150 liters.
Given the risk of landslides and flooding, particularly in mountainous and valley regions, camping vacationers are advised to consider an early departure from their plans. The peak of this inclement weather is expected on Holy Thursday, April 17, 2025, with unstable and rainy conditions persisting afterward. The storms are projected to shift further south starting Easter Monday, April 21, 2025.
For those with travel plans, it’s crucial to stay informed about the weather conditions. A travel law expert has indicated that travelers may be able to cancel their trips if "extraordinary circumstances" exist at their destination, which includes severe weather. However, they must provide proof, such as weather reports and news articles, and document any flight delays or cancellations.
As the weather unfolds, residents and travelers alike are urged to stay vigilant and prepared for the potential impacts of these severe storms. With significant rainfall expected across various regions, authorities are closely monitoring the situation to ensure public safety.
