More than 85% of the city of Venice was submerged, flooding the famous San Marco Square and Basilica, causing damage to the interior and exterior of the monument with high costs. Local authorities have set up several walkways to facilitate pedestrian movement, most of the shops, schools and administrative buildings have been closed. There are also two deaths reported on Pellestrina Island, one of the sand tongues that separates the city of Venice from the ocean, following flooding in dwelling houses. The “Mose” project, underwater mobile barriers designed to protect the city from flooding caused by southerly winds pushing the tide to Venice, is under construction. This project has been delayed several times due to excessive costs and corruption scandals. The authorities called for the rapid completion of the "Mose" project. The situation in the city took 5 days to normalize.

Only on March 19, the water level began to drop allowing rescue teams to reach the most affected areas. After the cyclone, the challenge of the medical teams was to contain the outbreak of cholera and malaria, registering about 1000 cases in the city of Beira, one of the most affected. The UN said “it is possibly the worst natural disaster ever to hit the southern hemisphere."

IDAI has also left its trail of destruction in Madagascar, Malawi, and Zimbabwe, where more than 700 people have lost their lives and hundreds of thousands of people were affected. The experts drew attention to the magnitude of this catastrophe which "sends a clear message that much more needs to be done in terms of disaster planning, emergency preparedness, and climate adaptation."
