Paris, France - A winter storm named "Xynthia" battered the western coast of Europe Sunday, its high winds downing trees and power lines and leaving as many as 51 people dead, authorities said.
Hardest hit was France, where at least 45 people were killed, French Prime Minister Francois Fillon announced.
The extra-tropical cyclone whipped the country's coastal regions and moved inland, bringing sometimes heavy flooding with it.
"It's a national catastrophe," Fillon said in a brief news conference. "Many people drowned, surprised by the rapid rise of the water."
The departments of Vendee and Charente-Maritime, on the French coast west of Paris, had severe flooding flooding when the strong winds whipped up the water at high tide.
