- Authorities confirmed two deaths: a woman killed by a falling tree in Saint-Victurnien (Haute-Vienne) and a man who died after lightning sparked a workshop fire in Dolomieu (Isère).
- Enedis reported about 53,000 households remained without power Friday morning as crews worked to repair fallen poles and lines while regional TER services and the Saint-Étienne–Lyon rail link faced sustained disruptions.
- Keraunos recorded roughly 35,000–40,000 lightning impacts in about 24 hours and emergency services mounted large operations, with hundreds of firefighters conducting hundreds of interventions in the Loire alone.
- The storms followed a 12-day heatwave and caused heavy material and agricultural damage, including hail losses in parts of Ardèche estimated at 30–80% on some parcels, with recovery and damage assessments still under way.
