Emergency management authorities in North Carolina said an earlier toll of 17 had risen to 25 since Florence made landfall Friday as a Category 1 hurricane, with its aftermath threatening further flooding as well as potential dam failures and landslides.
Experts are also concerned that Florence could produce damage similar to that wrought by the 1999 storm Hurricane Floyd, which contaminated North Carolina's waterways, drowned animals and produced harmful algal blooms.
That figure is down from a peak of over 2.2 million customers who were affected by the storm in several Southeast, Mid-Atlantic and New England states over the past week.
He described the period that SC is in as "the calm before the storm" and noted that residents of the area about to have a "rough few days" followed by a period of recovery that could last a long time.
Water appears to have receded in some areas of the Carolinas, but more flooding from Hurricane Florence could arrive through the weekend, officials say.
Twenty-four school districts remained closed as of Thursday, CBS affiliate WNCN-TV in Raleigh, North Carolina, reports.
Fox News only brought up climate change with regard to Hurricane Florence in order to dispute the connection. North and SC both backed Trump in the 2016 election, and the president largely saw people who were happy to greet him.
Access improved at least temporarily to Wilmington, a North Carolina port city of 120,000 that has been isolated for days by high water.
Rising water from the Waccamaw River and smaller creeks have started to close bridges around Conway, backing up traffic to the few roads left open.
More than a thousand other roads from major highways to neighborhood lanes are closed in the Carolinas, officials said.
"You're going to have a rebuilding process, and we are behind you from day one", Trump said, calling this the "calm before the storm, because you're going to have a lot of water".
In Fayetteville, the Cape Fear River was expected to reach major flood stage at 58 feet (17.6 meters) on Monday and to hit almost 62 feet (18.9 meters) on Tuesday before receding. Some of them have been washed out entirely.
Two years ago, flooding ruined the baseboards and carpet.
"I have just signed off on North Carolina's request for $14 million in immediate emergency relief funds to help address the infrastructure impact of Hurricane Florence", Secretary of Transportation Elaine Chao said in the press release.
This year, water from the Little River water broke the windows, leaving the pews a jumbled mess. One man had time to build a 6-foot-high (1.8-meter) dirt berm around his house.
He asked if everyone was OK, then said it was "going to be OK". Though the hurricane packed 90 miles per hour (145 kph) winds as it came ashore, the amount of water Florence pushed ashore and dropped inland has swamped vast areas still vulnerable to rising rivers.
