From Euronews:
"There are warnings of thunderstorms in many parts of France on Wednesday, in an abrupt interruption to the heatwave the country has been experiencing for weeks.
Violent storms and flooding was forecast for much of southern France, where an "orange" alert — the second highest level — was issued in five Mediterranean departments.
Paris was already struck by intense storms on Tuesday evening, dumping a large proportion of the French capital's average monthly rainfall in an hour and a half. "
I think it was 1971 when we were in Paris when there was a huge thunder and lightning storm. We had been out to the Champagne area and been doing tastings and had bought a very expensive bottle (forget the actual price) of Champagne called Rene Lalou which we were going to save for our first born. We got soaking wet running to our hotel room from the Metro so took off our wet clothes, dried off, and opened the bottle and drank it. At the time, it did seem miraculous we survived the lightning strikes and felt a celebration was in order.
We did keep the bottle for many years but I think it has now been lost in the shuffle.
