Violent Thunderstorms Expected Across France This Weekend: What You Need to Know
Introduction
As France transitions into spring, a major weather shift is set to bring violent thunderstorms and heavy rain across the country starting Friday, March 21, 2025. With several departments already on alert, here’s everything you need to know to stay safe and prepared.
Severe Weather Forecast: What to Expect
A depression forming over the Atlantic will introduce unstable atmospheric conditions, leading to widespread thunderstorms and heavy rainfall across various regions in France.
- Friday, March 21: The first storms will develop from the southwest, extending to the Île-de-France region by the afternoon and evening. These storms may bring heavy rainfall, occasional hail, and strong winds. The Cévennes region should be prepared for significant rainfall, while the southwest may experience powerful Autan winds with gusts exceeding 100 km/h.
- Saturday, March 22: Instability will persist, causing scattered showers and thunderstorms across much of France. Although the storms may not be as intense, the Cévennes region will continue to see sustained heavy rain, leading to possible localized flooding.
- Sunday, March 23: The storm activity will start to weaken, but occasional showers may still occur. Cooler oceanic air will move in, gradually bringing more stable conditions.
Is This Related to a Saharan Dust Event?
Saharan dust events occur when strong winds carry sand particles from the Sahara Desert into Europe, sometimes affecting France. These events can result in hazy skies, reduced air quality, and an orange or yellow tint in the atmosphere. While such events have impacted France in the past, the upcoming thunderstorms are not linked to Saharan dust. The current weather system is primarily caused by an Atlantic depression, leading to heavy rain and stormy conditions rather than dust transport.
