PARIS — Torrential rains across France and Germany left at least 16 people dead, drove thousands from their homes and forced the Louvre Museum to move its art treasures to higher ground.The floodwaters snarled traffic in this French capital and forced the closure of several railway and Metro stations. The Louvre was closed as staff removed artworks from lower rooms threatened by the rising River Seine that runs next to the museum. Leonardo Da Vinci's masterpiece, the Mona Lisa, is located on an upper floor and did not have to be moved.
