Extreme flooding forced thousands to evacuate their homes across Europe this weekend, with officials warning that historically high flood waters that have already claimed the lives of eight, are expected to rise further.

Four countries, Germany, Austria, Switzerland and the Czech Republic, are all under watch for potentially worsening conditions after officials confirmed the water levels are the highest they have been in 70 years, reported CBS Monday.

BBC reported that at least seven passed away from flood-related deaths this weekend, two dying in Prague after a cottage collapsed from flood waters, three others reportedly passing due to separate incidents. Two lives were also claimed in Austria due to the surge. Several others are still uncounted for, according to Czech police. CBS reported that eight perished from flood-related deaths with nine individuals still missing, as of Monday morning.

Flooding forced more than 7,000 residents in Eilbenburg, Germany, to be evacuated from their homes. An estimated 3,000 in Prague were also evacuated; animals at Prague's zoo were transported to safer conditions, reported the BBC.

“We will do everything to protect people’s lives and health,” said Czech Prime Minister Petr Necas. “Tonight and tomorrow will be critical,” he said.
