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

One person died from the storm in Georgia when a tree fell on a car in Lowndes County, along the Florida border, according to James Stallings, director of the Georgia Emergency Management and Homeland Security Agency.

Gov. Brian Kemp plans to visit south Georgia on Friday.

Florida Gov. Ron DeSantis said Thursday that he'll tour some of the hard-hit areas, like Cedar Key, to assess the damage.

Idalia has ripped down buildings, toppled trees and submerged entire neighborhoods.

DeSantis said there's a massive amount of debris left behind because Idalia struck a region with a lot of trees.

FEMA Administrator Deanne Criswell, who joined DeSantis at his briefing in Florida, added, "We are committed to bringing the entire federal family in here to support."

President Joe Biden spoke with DeSantis Thursday morning and signed a Major Disaster Declaration, according to the White House.

While at least two fatalities have been reported in Florida, Kevin Guthrie, director of Florida's Division of Emergency Management, said there are no confirmed deaths.

Over 140,000 customers in Florida are still without power and another 105,000 customers are waking up in the dark in Georgia in the wake of Hurricane Idalia.

Taylor County in Florida's Big Bend region, which includes the hard-hit city of Perry, is completely without power, Gov. Ron DeSantis said.

Idalia, now a tropical storm, churned over eastern North Carolina on Thursday morning, unleashing gusty winds and heavy rainfall as far as southern Virginia.

Meanwhile, a storm surge and coastal flooding was hitting North Carolina and its Outer Banks barrier islands.

A tropical storm warning remains in effect for the Carolinas, mostly for North Carolina.

Idalia is forecast to move out to sea by Thursday afternoon, taking the winds and rain with it.

The storm could bring gusty winds and heavy rain to Bermuda by late Sunday into early Monday.
