Roads in parts of Germany and France transformed into icy rivers and towns were blanketed in white following severe hailstorms and powerful winds. These violent storms occurred even as much of France remained under a heatwave alert, underscoring the volatile weather patterns affecting the continent.
Social media footage depicted vehicles navigating flooded streets and icy roads, while other clips showed hailstones described as golf-ball-sized impacting the ground. One video documented the damage inflicted on a car windshield by large hailstones.
In France, regions including Charente-Maritime, Ardeche, and Côte-d'Or experienced intense hailstorms on Wednesday. Overnight storms in Charente-Maritime damaged roofs and vehicles, and devastated vineyards. One agricultural professional reported that approximately fifteen hectares were affected, with seven to eight hectares suffering at least 50 percent damage, describing hailstones as large as ping-pong balls.
The Ardeche region later experienced a powerful hailstorm lasting nearly an hour and a half. Hailstones measuring several centimeters across shattered car windshields and caused substantial damage in Aubenas. The town's mayor, Jean-Romain Ribeyre, characterized the event as an "exceptionally violent phenomenon." According to local authorities, the storms brought heavy rain, intense lightning, strong winds, and hailstones exceeding five centimeters in diameter in some areas. Emergency services responded to over 200 calls, and 600 homes lost electricity. Approximately 30 firefighters were dispatched to address a fire suspected to have been caused by lightning.
Residents in Dijon, Côte-d'Or, were similarly surprised by the sudden storm. One resident described witnessing the wind intensify, followed by a dull thud before white hailstones began to fall, becoming so severe that blinds had to be lowered. Some hailstones were reported to be the size of ping-pong balls.
Further east, a supercell thunderstorm and a violent hailstorm struck the southern German city of Reutlingen on Thursday morning, resulting in widespread damage. The storm caused flooding and covered roads with thick layers of hail, turning streets into icy conditions as emergency crews worked to clear debris.
Meteo France indicated that further storms were anticipated for Thursday, particularly in the morning across Brittany, Gironde, and the Pyrenees. The agency warned of a more significant storm system developing around midday, moving from the Pays de la Loire region towards Massif Central, Burgundy, and the northern Rhône-Alpes region. These storms could bring hail, strong gusts of wind, and between 30 to 50 mm of rain, with localized amounts potentially higher. Another strong storm system was also forecast to form around midday over Languedoc-Roussillon.
These severe weather events coincide with expert warnings that temperatures of 50°C (122°F) are "perfectly possible" in southern Europe in the coming weeks. Europe is currently experiencing a significant heatwave, with parts of Spain reaching 44°C (111.2°F) over the past week. This intense heat has fueled wildfires across France and Spain, leading to the evacuation of thousands of people. Official figures show that deaths in France increased by nearly a third during the hottest week recorded in June, with over 2,000 excess deaths attributed to the June heatwave and 300 during temperatures in May. Temperatures reached 40°C (104°F) in western and central France, peaking at 37°C (98.6°F) in Paris, marking the country's third heatwave since May.
In response to the extreme heat, the French government announced the opening of "cooling centres" for vulnerable populations, including the elderly and homeless. Experts from the Copernicus Climate Change Service (C3S) confirmed that the past month was the hottest June ever recorded for western Europe. Samantha Burgess, Strategic Lead for Climate at ECMWF, stated that the records underscore the profound changes in the climate, leading to increasingly intense heatwaves, persistently warm oceans, and growing risks for people, ecosystems, and infrastructure across Europe and beyond.
