A massive flood wave moving across Central Europe was threatening new areas and raising concerns among residents and leaders. It also prompted European Union head Ursula von der Leyen to plan a visit to the region on Thursday.

The storms battered 19 localities in eight counties in Romania, with strong winds downing dozens of trees that damaged cars and blocked roads and traffic.

At least four people died and thousands of homes were damaged by flooding in eastern Romania on Saturday, officials said, as surging river levels put authorities on alert in much of central and eastern Europe following days of torrential rain.
