The death toll from Hurricane Ian has reportedly risen to nearly 100 in Florida as rescue personnel continue to search for survivors.

On Monday, Mr Biden visited Puerto Rico - which was struck by Hurricane Fiona just days before Ian struck Florida - where he promised $60m (£53m) in aid to help the US territory.

According to the BBC's US partner network CBS, the hurricane's death toll in Florida climbed to at least 99 on Monday night.

Florida officials said the latest death toll is at least 68.

The figures differ as while local officials may report additional storm-related deaths, the medical examiner's officer is only attributing a death to the hurricane after an autopsy is performed.

The majority of the deaths - 54 - have been reported in Lee County, which includes the hard-hit areas Fort Myers, Sanibel and Pine Island, Sheriff Carmine Marceno said at a news conference.

On Friday, Florida governor Ron DeSantis described the county as "ground zero" for the hurricane.

While the death toll from Hurricane Ian already makes it one of the deadliest hurricanes in recent memory, it still pales in comparison to 2005's Hurricane Katrina, which killed more than 1,800 people.

In the wake of the storm, officials in Lee County have faced questions about the timing of their evacuation order, which was issued on 27 September, less than 24 hours before Ian made landfall.

The death toll cited by Florida officials does not include at least 16 Cuban migrants who remain missing after their boat capsized off the state's coastline during the hurricane.

The utility company with the largest number of outages, Florida Power & Light Co, said that the majority of customers will have their power restored by 7 October, but that storm damage has made some properties "unable to safely accept power".
