The village of Lévis-Saint-Nom (Yvelines), 1,600 inhabitants, was severely affected by the heavy rainfall this Thursday morning. Cellars and garages transformed into swimming pools.

At the height of the downpour, a “tiny river, which doesn't even have a name”, overflowed. “When you have 70 cm of water in your living room, you lose a lot and it's difficult to overcome,” says the mayor.
