Hurricane Ian, which peaked at a category four storm, is bringing severe flooding, high winds and storm surges to the Florida coast.

It is now losing power as it moves inland, and has been downgraded to a category one system.

More than two million customers in Florida have no electricity as a result of the hurricane.

The roof of the ICU ward at a hospital in Port Charlotte has been ripped off, a doctor who works there has said.

Dr Birgit Bodine told US media that the lower levels of the building were also flooded, meaning the sickest patients – who are all on ventilators – had to be evacuated to other parts of the hospital.

Videos shared on social media show puddles of water on the floors, with towels scattered trying to dry them up and buckets all over the place.

“For us, as much as everything is terrible and we’re exhausted... as long as our patients do OK and nobody ends up dying or having a bad outcome, that’s what matters,” Dr Bodine told the Washington Post.

The hurricane made landfall on Wednesday afternoon with maximum sustained wind speeds of 241km/h (150mph) near the city of Fort Myers.

Florida Governor Ron DeSantis warns people in the storm's path to get ready for "a nasty, nasty" couple of days.

US Border Patrol is looking for up to 23 migrants missing after their ship sank during the storm.

The hurricane barrelled through Cuba on Tuesday, killing two people and shattering the country's electrical grid. (Pieced together from BBC reports)
