Pommeuse's first deputy mayor Lysiane Finot has often heard her phone ringing. The fault is the rising waters of the Grand Morin, which is acting up again.

“It’s normal, people were scared. In places, there were real stunts in the streets. Already last Wednesday, we had to ban parking on Place Alphonse-Vion. But this is worse,” she says. The only bridge still open, which allowed access to the square, was finally closed to traffic.
