Saint-Victurnien – 18/07/2026: The severe thunderstorms on Thursday evening claimed at least two lives in France. In Saint-Victurnien, in the Haute-Vienne department, a woman was struck by a falling tree and fatally injured. In Dolomieu, in the Isère department, a man was found dead after a fire in a workshop. According to initial reports, the fire was caused by a lightning strike.
The storms swept across large parts of the country on July 16, bringing heavy rain, hail, strong wind gusts and an exceptionally high number of lightning strikes. Météo-France recorded more than 20,000 cloud-to-ground lightning strikes. According to the weather service, this made it the day with the highest lightning activity in France so far in 2026.
Regions from Nouvelle-Aquitaine to Auvergne-Rhône-Alpes were particularly affected. Fallen trees, damaged power lines and flooded roads hampered emergency services. In several departments, firefighters, road maintenance crews and grid operators had to deal with numerous incidents simultaneously. Authorities had previously urged particular caution in many areas because of the expected severe thunderstorms.
According to electricity grid operator Enedis, around 53,000 households nationwide were still without power on Friday morning. The main affected areas were Auvergne-Rhône-Alpes, with around 25,000 customers affected, and Nouvelle-Aquitaine, with about 20,000 connections. The largest known outages were reported in Dordogne, Loire and Charente.
In the Loire department, firefighters carried out more than 600 operations, according to local authorities. They were called mainly because of fallen trees, damaged roofs, flooded areas and blocked transport routes. Emergency crews in Ardèche were also continuously deployed following severe thunderstorms. There, the prefecture reported numerous calls for help and several damaged transport and power connections as early as July 15.
The electricity grid operator deployed repair teams to inspect damaged lines and gradually restore service to households. Enedis initially did not publish a complete current update on outages on Saturday. It is therefore not possible to say with certainty how many households were still without electricity on July 18. The figure of 53,000 refers to the status on Friday morning.
The events followed a prolonged period of heat. Thunderstorms can be particularly intense after high temperatures when very warm and humid air discharges rapidly. For the affected communities, restoring the power supply, securing damaged buildings, removing fallen trees and fully clarifying the two deaths are now the main priorities.
