A Florida law enforcement spokeswoman confirmed to AFP on Saturday morning a provisional toll of 23 victims, most of them drowning and the vast majority of them elderly.
Some American media have mentioned an even heavier human toll, the CNN channel putting forward the figure of 45 deaths.
At the same time, the search continued to find 16 passengers from a migrant boat which capsized due to bad weather on Wednesday near the Keys archipelago.
The Coast Guard said it found two people from the boat dead in the water, with nine others rescued either offshore or after swimming to shore.
After ravaging Florida, Ian headed for South Carolina, where it made landfall Friday afternoon near Georgetown as a Category 1 hurricane, with winds up to 140 km/h, according to the Miami-based National Hurricane Center (NHC).
– Unprecedented –
Saturday morning, Ian was carrying winds of up to 35 km / h with still “heavy rain” on the Appalachian Mountains in the southeastern United States, the NHC said in its latest bulletin.
“Post-Tropical Cyclone Ian will continue to weaken near the Virginia-North Carolina boundary well into the day,” the NHC said.
Despite its weakening, the authorities of several southeastern states still called on the population to be cautious because of the heavy rainfall expected.
More than 500,000 homes and businesses were without power Saturday at midday in North Carolina, South Carolina, and Virginia, according to the specialized site poweroutage.us.
Florida still had 1.2 million homes and businesses without power.
In the peninsula, in addition to the heavy human toll, the material damage is “historic”, the level reached by the rising waters having been unprecedented, according to Governor Ron DeSantis.
Streets and homes were flooded and boats moored in marinas were tossed onto land by the storm. On Friday, in Kissimmee, not far from Orlando, the authorities crossed the flooded areas in boats to rescue residents trapped in their homes.
– Years to rebuild –
In this state, “we are just beginning to see the extent of the destruction”, “likely to rank among the worst” in the history of the United States, said Joe Biden during a speech.
“It will take months, years to rebuild,” he lamented.
In the coastal town of Fort Myers, called the “epicenter” by Ron DeSantis, a handful of restaurants and bars had reopened and dozens of people were seated on terraces, offering residents a semblance of normalcy between broken trees and destroyed facades.
“It was pretty terrible, but we held on. The roof of our house blew off, a big tree collapsed on our cars, our garden was flooded, but other than that, it’s fine,” said Dylan Gamber, 23, welcoming the solidarity that reigned between neighbors.
According to initial estimates, the passage of Hurricane Ian could cost insurers tens of billions of dollars and will weigh on American growth, in particular due to flight cancellations and damage to agricultural production.
– “Wetter” –
According to a first rapid study by American scientists made public on Friday, the rains linked to Hurricane Ian have increased by at least 10% due to climate change.
“Climate change didn’t cause the hurricane, but it did make it wetter,” said one of the scientists involved in the study, Michael Wehner, of the Department of Environment’s Lawrence-Berkeley National Laboratory. Energy, .
Before Florida, Ian had hit Cuba, causing three deaths and extensive damage and leaving many homes without power there too.
