Violent storms, hail, and winds over 100 km/h to hit France this weekend

France is bracing for a significant shift from intense heat to violent thunderstorms this weekend, particularly affecting the country's southeast. After days of soaring temperatures, with some regions nearing 40°C, a depression moving in from the Atlantic on Saturday will trigger a clash of air masses, creating conditions ripe for severe weather.

This 'air mass conflict' will create conditions favorable for sometimes violent thunderstorms.

The meteorological service La Chaîne Météo forecasts that regions like Languedoc, Provence, and much of Auvergne-Rhône-Alpes will be most exposed. Storms are expected to develop Saturday afternoon and intensify into the evening and early night, bringing potentially dangerous phenomena. These include heavy rainfall of 30 to 60 mm in short periods, which could lead to flash floods, as well as significant hail and wind gusts potentially exceeding 100 km/h.

Under the most active cells, La Chaîne Météo forecasts 'heavy rain in a short time (30 to 60 mm, locally more)', likely to cause 'localized runoff and flooding'.

While the rain might offer some relief to dry soils in areas spared from hail, its localized nature will limit its overall impact. Authorities are urging caution, especially with many people traveling for holidays and outdoor events planned. The combination of extreme heat followed by severe storms highlights the volatile weather patterns affecting France.

Hailfalls sometimes significant and wind gusts that could 'exceed 80 to 100 km/h' are also possible.
