Florida Gov. Ron DeSantis shared a major update on power restoration progress in the state on Sunday.

DeSantis said a post on X that most customers who lost power after Hurricane Helene made landfall in Florida's Big Bend area last week, have had their electricity restored.

The governor said power was back for 2.3 million customers, and 99% of the state has power.

He added that power remains out for 111,000 customers.

President Joe Biden spent his Sunday evening receiving briefings on the damage from Hurricane Helene, and speaking to local officials from the impacted areas.

In a statement, the White House said Biden intends to travel to the impacted areas this week, "as soon as it will not disrupt emergency operations."

Additionally, Biden spoke by phone Sunday with Georgia Gov. Brian Kemp, North Carolina Gov. Roy Cooper, Valdosta, Georgia, Mayor Scott Matheson and Taylor County, Florida, emergency management director John Louk, according to the White House.

The president also reached out to additional officials across North Carolina, Tennessee, Florida and South Carolina.

"In each conversation, the President received updates on response and recovery efforts, and he shared how the Biden-Administration will continue providing support to impacted communities – for as long as it takes," the White House said in the statement.

Former President Donald Trump is scheduled to visit Valdosta, Georgia, on Monday to receive a briefing on the damage caused by Hurricane Helene, help distribute supplies and deliver remarks, his campaign said.

President Joe Biden said Sunday that the photographs showing Hurricane Helene's damage are "stunning."

When asked by reporters about his message to the victims, Biden said, "It's tragic."

"My FEMA advisor is on the ground in Florida right now. … We're working hard," Biden said.

Asked by ABC News if there are more resources the federal government could be providing, Biden responded, "No, we've given them. We have pre-planned a significant amount, even though they didn't ask for it yet -- hadn't asked for it yet."

Helene is "an unprecedented storm" for western North Carolina, requiring an "unprecedented response," North Carolina Gov. Roy Cooper said Monday.

"We’re dealing with a situation that is unlike anybody’s ever seen in western North Carolina," he said.

The damage is "extensive and devastating" and is "going to require significant resources, both in the short-term and the long-term," the governor said.

Ninety-two rescue teams are out conducting search and rescues right now, Cooper said.

More than 300 roads are closed and some bridges have been destroyed, officials said.

Over 7,000 North Carolina residents have registered for FEMA individual assistance and that money is already flowing in, according to Will Ray, director of North Carolina Emergency Management.

FEMA Administrator Deanne Criswell promised that the agency will "be here as long as it takes to finish this response and continue through the recovery."

"We have the resources here in North Carolina to help," Criswell said. "We will continue to send additional resources in."
