Thousands of people have been evacuated as floods continue to threaten homes and businesses across the Paris region.
French authorities said areas along the River Loing, a tributary of the Seine, had seen waters rise to levels unseen since 1910, when a massive flood swamped the capital.
Media reported evacuations in the town of Nemours, about 50 miles (80km) south of Paris. The iTele broadcaster said 400 firefighters and police were at work there removing people from flood-hit homes.
France's meteorological service said on Thursday that severe flood watches are in effect in two Paris-area departments - Loiret and Seine-et-Marne.
Eight other departments, including three on the German border, face flood warnings.
The German state of Bavaria has promised quick financial help to residents in areas near the Austrian border hit by flooding.
According to the dpa news agency, Bavaria's governor, Horst Seehofer, has pledged "quick and un bureaucratic help", saying his state "won't abandon those affected, some of whom have lost their whole homes".
Four people have been confirmed killed in the flooding, which swept through the towns of Simbach am Inn and Triftern, while others have been reported missing.
The waters have receded, and disaster relief crews were on the scene helping to clear the wreckage, while helping to prepare for more possible flooding. There are warnings of more storms in the forecast.
