The river Seine could hit a level of 6 metres in Paris on Friday, according to a regional government website, further dousing a city that had already seen 5 metres of water the day before.
The forecast on the Ile-de-France site called for between 5.7 and 6 metres and listed a series of closures throughout the city, focused on the central Austerlitz underground station.
The Energy, Ocean and Environment Ministry classified river levels around Paris as being at level orange, the second-highest risk level.
The flooding has prompted the Louvre museum to close its doors so staff members can bring artwork upstairs and out of areas vulnerable to flooding from the Seine River
France's culture minister was meeting with representatives of museums and cultural institutions affected by flooding at the Louvre Museum on Friday.
"Today due to the level of the river Seine, the Louvre is closed to ensure the protection of the works," the museum said. Culture Minister Audrey Azoulay said she would meet affected institutions in the late morning.
The Seine is swollen from a week of rain that has caused high waters and thousands of evacuations in northern France.
