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

Idalia, now a tropical storm, touched down in Florida as a Category 3 hurricane.

Idalia touched down in Florida's Big Bend region on Wednesday morning as a powerful Category 3 hurricane -- the strongest hurricane to ever make landfall in the Apalachee Bay.

Idalia has since weakened into a tropical storm and moved inland over Georgia and the Carolinas.

Biden to visit Florida on Saturday

President Joe Biden plans to travel to Florida on Saturday to survey the damage from Hurricane Idalia, he told reporters during a visit at FEMA headquarters.

The visit was billed as one to thank FEMA staff for their work during the hurricane and the Maui wildfires.

Biden noted that he once again spoke with Florida governor and 2024 presidential candidate Ron DeSantis on Thursday.

"Governor DeSantis and I spoke again this morning and let him know that I accrued his major disaster declaration," Biden said.

Charleston 'dodged the bullet': Mayor

Charleston, which is vulnerable to flooding, recorded a storm surge of 3.47 feet -- its fifth highest on record.

But Charleston Mayor John Tecklenburg said the city "really dodged the bullet" of Hurricane Idalia.

"The wind and the rain impact were pretty minimal," he said Thursday.

Twenty-two water rescues were reported, which mostly were for people trapped in flooded cars, the mayor said.

'Significant damage' in the Big Bend region: DeSantis

Gov. Ron DeSantis said there is "significant damage" throughout the Big Bend region, with Columbia, Madison and Dixie counties hardest hit.

"There is, of course, a lot of debris to clean up. But we will get working with that with the local communities to make sure that the roads are cleared and people can go back to their lives," DeSantis said during a press briefing.

As of 6 p.m. there is one unconfirmed fatality due to the storm involving a traffic incident that the Florida Department of Law Enforcement is reviewing, the governor said.

"That may end up being a confirmed fatality, it has not been confirmed yet," DeSantis said.

Thirty of the 52 school districts that closed due to the storm will reopen Thursday, and an additional eight will reopen on Friday, the governor said.
