SICILY, Italy - With the deaths of 12 people in Sicily, the death toll in Italy's historic flooding has grown to 29, the country's interior minister said.
"Twelve dead in Sicily, people that were having dinner and were swept up by the water," Interior Minister Matteo Salvini said in a statement to the press in the northern region of Veneto.
High winds and heavy rain have devastated parts of the country over the past week, causing the worst flooding in at least a decade in Venice, damages of more than 1 billion euros ($1.14 billion) in Veneto and landslides that have cut off villages, authorities said.
The situation in Sicily is "dramatic," Prime Minister Giuseppe Conte said Sunday.
Italy's Civil Protection Agency continues to monitor the situation, issuing weather warnings via Twitter, while volunteers from the Italian Red Cross work to rescue people.
Several of last week's deaths were caused by falling trees as winds as strong as 190 kilometers per hour (118 mph) toppled acres of woodland, including the famous "Violin Forest" that provided wood for violin maker Antonio Stradivarius' instruments.
Two young people died south of Rome when a tree hit their car. Another was hit by a falling tree while walking in Naples.
Around 300,000 trees were flattened after winds swept through the Val d'Assa in the Asiago plateau, Roberto Ciambetti, president of the Veneto Regional Council, told CNN.
"Tens of thousands of tall trees were felled like toothpicks," he said.
Much of Venice was under water as strong winds on Monday drove the high tide to one of the highest levels ever recorded.
St. Mark's Square became a lake, and floodwater spilled across the ancient marble floors of St. Mark's Basilica.
"In a single day, the basilica aged 20 years, but perhaps this is an optimistic consideration," Carlo Alberto Tesserin, head of the board responsible for St. Mark's Basilica, said in a statement.
This week's flooding was caused by a seasonal high tide and a strong low-pressure system in southern Europe that brought strong winds from the south and pushed water up the Adriatic Sea into Venice. This is the peak time of the year for seasonal flooding known as acqua alta, or high water, in the city.
Flooding at high tide has become much more common in Venice because of climate change -- a problem that will continue to worsen as seas rise because of increasing temperatures and melting ice sheets, according to CNN meteorologists.
