At least 105 people have died in Florida and five in North Carolina, according to CNN as of Wednesday.
US President Joe Biden traveled to Fort Myers, Florida, on Wednesday to survey storm-ravaged areas.
Nearly 300,000 customers in Florida were without power as of Wednesday afternoon, according to PowerOutage.us.
Ian made landfall in southwest Florida last week, bringing catastrophic storm surges, heavy rains, damaging winds, and dangerous flooding.
Biden previously said Hurricane Ian “will probably rank among the worst in the nation’s history.”
Estimated losses from Ian’s wind and storm surge are between $28 billion and $47 billion, according to CoreLogic, a US firm that estimates losses from natural disasters.
It could be Florida’s costliest storm since Hurricane Andrew in 1992.
