Hurricane Helene updates: Death toll surpasses 230 as rescue efforts continue

Vice President Kamala Harris called the storm damage throughout the Southeast the "worst destruction and devastation that we have seen in quite some time" during remarks from FEMA's headquarters in Washington, D.C., Monday afternoon.

"In coordination with state and local officials, President Biden and I will continue to make sure that communities have the support and the resources that they need -- not only to respond to this storm and its immediate aftermath, but also the resources they will need to recover," Harris said.

Harris said more than 3,300 federal personnel are on the ground to assist with recovery efforts, including deploying food, water and generators as well as helping to restore water and power.

"To everyone who has been impacted by this storm, and to all of those of you who are rightly feeling overwhelmed by the destruction and the loss, our nation is with you," she said. "We will continue to do everything we can to help you recover and to help you rebuild. No matter how long it takes."

Harris said she has spoken to Georgia Gov. Brian Kemp and North Carolina Gov. Roy Cooper and plans to be "on the ground as soon as possible" without disrupting any emergency response operations.

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."

Homeland security adviser Liz Sherwood Randall said the full extent of the damage from the hurricane is still unclear.

“It probably will take several more days, as communities begin to be opened up by the debris clearance on the roads, and we can get in, and really understand what's happened to them," she said.

Sherwood-Randall said about 600 people are unaccounted for.

“We're very hopeful that some of those people just don't have cellphones working and actually are alive," she said.

Sherwood-Randall said 3,500 federal response personnel have been deployed to the region and additional personnel is expected to arrive in the coming days.

With communication remaining a major challenge, Sherwood-Randall said, "Today, FEMA will install 30 Starlink receivers in western North Carolina to provide immediate connectivity for those in greatest need."

She also highlighted that in states that have received major disaster declarations, FEMA is working to distribute serious needs assistance, which gives "an immediate $750 direct payment to eligible households, to allow them to pay for essential items like food, baby formula, water, medications and other emergency supplies."

Sen. Rick Scott, R-Fla., is calling upon the Senate to reconvene to approve an emergency aid package for victims of Hurricane Helene.

"While I know from my experience with previous hurricanes that FEMA and [Small Business Administration] damage assessments take time, I am today urging Majority Leader Chuck Schumer to immediately reconvene the U.S. Senate when those assessments are completed so that we can pass the clean supplemental disaster funding bill and other disaster relief legislation, like my Federal Disaster Tax Relief Act, needed to ensure the full recovery of families in all impacted communities," Scott said in a statement Monday.

Any additional funding, beyond the funding approved by President Joe Biden and able to be drawn down from FEMA, would need to be approved by both chambers of Congress.

The Senate let out on Wednesday after approving a stopgap funding bill to keep the government funded through Dec. 20. The Senate is not scheduled to return until Nov. 12. The House is also out of session and would need to return to approve any aid.
