The government of Italy has announced an emergency in Venice, following the devastating floods this week (Tuesday and Wednesday) that have submerged 85% of the city. High tides (also called Acqua alta) powered by Southerly winds have caused hundreds of millions of euros worth of damage. This is the worst flood to hit the city in 50 years, recording water levels at 1.87 metres on late Tuesday. The only other flood to beat this number was that of 1966 when 1.94 metres were recorded.
