The European heatwave has triggered severe thunderstorms across France, Germany, and Poland, bringing golf ball-sized hailstones, flooding, and power outages. These storms follow an exceptional period of extreme temperatures, with hailstones ranging from 5cm to 7cm reported in southeastern French villages like Aubenas and Vals-les-Bains. Streets were blanketed in hail, damaging vehicle windscreens, buildings, and vineyards, while torrential rainfall and strong winds caused localized flooding.
Record Heatwave and Thunderstorm Impacts
Thunderstorms are common after prolonged heat, but the intensity of these storms has been unusual. In Wrocław, Poland, roads and tram tracks were closed due to flooding and fallen trees on cables. Residents were advised to stay indoors and prepare for potential power outages. Forecasts predicted 30-50mm of rain in France, with higher local amounts.
