Venice city officials say 28 percent of the lagoon city has been flooded by waters rising 110 centimeters (more than 43.3 inches) above sea level.
The tidal event will be characterized by a rather important astronomical component (81 centimeters) to which the effects of the perturbation will be added.
The tidal value of 110 cm occurs very rarely in May: the historical archive of the Centro Maree reports only 4 cases from 1872 to today and this only confirms the atypical nature of this year’s spring.
