Idalia updates: Damaging tornadoes, severe flooding from Florida to Carolinas

Despite reports of fatalities from Hurricane Idalia -- including at least one death in Pasco County confirmed by the Florida Highway Patrol -- Florida Gov. Ron DeSantis said Wednesday that none of the reported deaths have yet been confirmed.

"There’s a process for confirmed fatalities that just goes through law enforcement and medical examiners. … That has not been done yet where we've had a confirmation," he said.

Health facilities largely avoided damage and evacuations, Florida Division of Emergency Management Kevin Guthrie said.

"As of this minute, there have been no reports of any issues inside the health and medical industry, whether that’s assisted living facilities, skilled nursing facilities, nursing homes or hospitals," he said.

The city of Perry, Florida, suffered some of the heaviest damage, officials said. Multiple businesses were on fire and several buildings lost their roofs.

Over 270,000 customers in Florida lost power due to Idalia. The governor said crews are working quickly to restore power to those still in the dark.

A 100-year-old oak tree split open and toppled onto the governor's mansion in Tallahassee, Florida, on Wednesday, according to a tweet from Casey DeSantis, wife of Gov. Ron DeSantis.

Casey DeSantis said she and their children were home at the time but were not hurt.

In Pasco County, Florida, just north of Tampa, authorities helped evacuate more than 60 people from flooded homes, according to the sheriff's office.

The county is facing flooded roads, downed trees and downed power lines in the aftermath of Idalia, the sheriff's office said.

American Airlines said it's suspended operations in Tampa, Sarasota, Tallahassee, Gainesville and Savannah as Hurricane Idalia tears through.

Tampa International Airport, which closed ahead of the storm, will reopen at 4 p.m. Wednesday.
