Hurricane Helene live updates: 121 dead, including 35 in hard-hit county

President Joe Biden said Monday that Helene is "not just a catastrophic storm -- it's a historic, history-making storm."

Biden said he will travel to the impact zone as soon as possible, ideally Wednesday or Thursday. He said he’s been told it’d be disruptive to visit immediately, and he does not want to interfere with these areas accessing the relief they desperately need.

"Communities are devastated. Loved ones waiting, not sure if their loved ones are OK, and they can't contact them because there’s no cellphone connections. Many more folks displaced have no idea when they’ll be able to be return to their home, if ever, if there’s a home to return to," he said.

"There's nothing like wondering, 'Is my husband, wife, son, daughter, mother, father, alive?' And many more who remain without electricity, water, food and communications," he said.

Biden said he’s directed his team "to provide every available resource as fast as possible."

Biden vowed, "We're not leaving until the job is done."

Hurricane Helene "literally spared no one" in Georgia, Gov. Brian Kemp said Monday.

Twenty-five people in Georgia have died in the storm, Kemp said. The victims include: a 27-year-old mother and her 1-month-old twin boys, who died when a tree fell on their home; Leon Davis, an assistant fire chief from Blackshear, who died when a tree fell on his car while he was responding to a call; and a 7-year-old boy and a 4-year-old girl who died when a tree fell on their burning house, he said.

More than 500,000 customers in Georgia remain without power after Helene damaged over 5,000 poles, the governor said. Kemp said Georgia Power officials are calling Helene the most devastating storm they’ve faced.

Former President Donald Trump is scheduled to visit hard-hit Valdosta, Georgia, on Monday.

Thirty-five people are dead and 600 people remain unaccounted for in hard-hit Buncombe County, North Carolina, which encompasses Asheville, according to county officials.

County officials said people will go door-to-door to check on those who have been reported missing.

Shelters are at capacity, officials said.

The city of Asheville has partnered with Verizon to establish a temporary cellphone tower, officials said. County officials said they’ll start distributing water Monday afternoon.
