Subsidence had led to the seasonal Acqua alta when much of the city's surface is occasionally covered at high tide.
Well, we are here at this very special time!!!! And there's more!!!
Not only does the water in the canals rise and fall with the tide of the Adriatic Sea, there's been a full moon which increases the rise and fall. There is also a big storm moving through this part of the country, bringing with it a lot of rain and wind.
