After Hurricane Ian passed through Florida, the death toll continued to rise.

As the broadcaster CNN and representatives of various local authorities reported on Thursday, at least twelve people were killed by the devastating storm.

After "Ian" temporarily weakened to a tropical storm, the US Hurricane Center NHC later classified it as a hurricane again and continued to warn of "life-threatening, catastrophic" storm surges, strong winds and rain.

US President Joe Biden had previously said in Washington during a visit to the headquarters of the US disaster protection agency Fema that "Ian" could be "the deadliest hurricane in Florida history".

The situation is still dangerous, warned Biden.

"We continue to experience deadly rains, catastrophic storm surges, flooded streets and houses," he said.

"We see millions of people without power -- and thousands sheltering in schools and community centers." These people wondered what was left of their homes, or if they would have homes at all.

The head of the civil protection agency Fema, Deanne Criswell, said: "Hurricane "Ian" will be a storm that we will be talking about for decades."

"Ian" made landfall on Wednesday as one of the strongest hurricanes in Florida's history and caused major damage there.
