As the rain continues to fall, the authorities are preparing to face significant flooding in Seine-et-Marne. The department was placed on red flood alert this Wednesday at 4 p.m. by Météo France, due to the risk of flooding around Grand Morin. “The expected amounts of rain could cause a strong to exceptional flood”warns the government site Vigicrues, “with very rapid water rises and overflows from this Wednesday evening.”
At 4 p.m., Météo France recorded between 15 and 30 millimeters of rain having fallen since the start of the day in Seine-et-Marne. And up to 80 mm cumulative could fall by Wednesday evening, the equivalent ofa month of rain in one day. These accumulations of rain could cause numerous floods in the communities around Grand Morin. And the water will continue to rise on Thursday. “The maximum in the Pommeuse sector should be observed in the morning or during the day on Thursday”specifies Vigicrues.
School transport suspended Thursday
The Seine-et-Marne prefecture has decided to suspend school transport for Thursday. In La Ferté-Gaucher, schools will be closed on Thursday, the mayor told France Bleu Paris. All outdoor activities and events are also prohibited, by prefectural order, until Friday noon.
In several towns, the municipal safeguard plan has been activated. This is the case in Bellot, a town which suffered significant flooding last summer, at the beginning of August. “As the town hall is in a flood zone, we moved ittells France Bleu Paris Frédéric Morel, the mayor of Bellot. “There is going to be more rain than in August, the peak is expected at 10 p.m. But here, we are affected by runoff floods so depending on where the water falls, we can move on to through”he explains.
In Crécy-la-Chapelle, we are also preparing for the worst. “We expect to be flooded”explains to France Bleu Paris M. Pailloux, the general director of services. “We distributed concrete blocks to residents so that they could secure their homes and the municipal police went around to the elderly people in the town to warn them”he continues.
In La Ferté-Gaucher, already affected three times by overflows from the Grand Morin this year, the mayor recommends that residents limit their travel. Michel Jozon therefore issued an order to keep the schools and colleges in his town closed on Thursday October 10. The Forgeard community hall was also opened to accommodate possible victims.
