The Seine at 5.10 m
In Paris, the Seine continued its rise Wednesday and exceeded 5.10 m. It is expected to peak in the night from Friday to Saturday, at levels comparable to the flood of June 2016 (6.10 m).
The RER C line was closed on Wednesday in the capital and at least until Friday.
“In Paris, outside the banks, the consequences should be the same in 2016,” especially with a risk of infiltration by Jérôme Goellner, head of state services in charge of the environment in the region (DRIEE ).
However, forecasters were watching closely the development of the Marne Wednesday.
“Downstream of the confluence with the Marne, the heights will be comparable to 2016,” warns Joel Hoffman, deputy director of Vigicrues. “It monitors the downstream portion Yonne Joigny, Pont-sur-Marne …”
In contrast, “the water rises in Melun, Villeneuve-Saint-Georges, but at lower heights in 2016”.
At the origin of this national phenomenon, significant rainfall fell on waterlogged soils. France has experienced the second two-month period from December to January the wettest since records began in 1900, according to Météo France.
This phenomenon is still “relatively conventional for the winter. But its size gives it exceptional, “notes Marc Mortureux, director of risk prevention at the Department of Ecological Transition.
“The situation is serious but there is no need to unduly anxious today,” said Tuesday the Secretary of State Ecological Transition Brown Poirson.

Elsewhere, a “moderate” flood was under way on the Rhone downstream of Lyon.
In the Northeast, “levels remain high in many rivers, especially on the Maas and the Rhine.”
The propagation of the wave of the upstream raw Doubs, was to join the Saône, “who will have to cash in,” warns Vigicrues.
In the east, the Rhine flood peak was reached Tuesday night, said the prefecture of Bas-Rhin, who stressed that the decision to fill a polder 600 hectares had “done its work by stopping the flood.”
“The decline starts slowly, even if the water levels are still very high,” she added.
Navigation on the river, arrested Tuesday was able to return to “some very minor sections below, but conditions remain difficult for navigation,” she said.
In red alert on Monday after overflow of rivers Loue and Doubs Montbéliard reached its flood peak. This should also be the case in Besancon at night.
