Greenville was by far the hardest hit area for power outages in Duke's South Carolina territory, reporting 1,233 locations without power.
In the Midlands, Fairfield County reported 672 power outages at noon and Kershaw County reported 385.
"The outages are due to a combination of saturated ground, heavy rains, and moderate wind gusts, and those create a perfect situation for downed trees and power lines," said Jennifer Jabon, spokeswoman for Duke Energy Carolinas in Greenville. "We do recognize there is still a potential for outages due to heavy rains and winds that are also forecast to continue across the area."
Teams of power crews in the Carolinas are working to restore the power losses, Jabon said, and additional crews from neighboring states also stand ready to respond if such needs arise, she said.

At least two to four additional inches of rain was expected by noon. Barbara Vaughn, a Charleston city spokeswoman, said several people were rescued from stranded cars there.
The Charleston Police Department has issued lists of dozens of street closings, and the city’s historic district was almost entirely shut down. Parts of the market area had sandbags piled up to keep the floodwaters out.
Portions of some streets were flooded, with water roughly 8 to 12 inches deep, reaching the wheel wells of cars in some spots. Police have stationed officers and set up barricades all over the city blocking roads. No one is being allowed into Charleston, and once people drive out, they won’t be allowed back in until the flooding subsides.
In one area, water swirled like a toilet down a storm drain. Public works crews patrolled the city, checking storm drains in case they needed to be cleared of debris.

Midlands residents are experiencing weather-related power outages this Saturday morning, particularly in Lexington and Richland counties, according to SCE&G.
As many as 1,200 customers lost power in Lexington County overnight when a tree fell on a line, said SCE&G spokeswoman Ginny Jones. About half those customers had been restored by 6:30 a.m., she said. At last check, 679 customers were without power, but crews were working to restore those as quickly as possible, Jones said, within the next couple of hours.
In Richland County, about 100 customers were without power as a result of the weather, Jones said. SCE&G has about 159,000 customers in Richland County, and about 97,000 customers in Lexington County.
Surprisingly, Jones said, Charleston County, where significant flooding and street closures are being reported, only about 55 customers are out of power in the SCE&G service areas.
Columbia had yet to be hit by floods from the storm as of 6:20 a.m. Saturday, assistant city manager Missy Gentry said.

A spokesman with the S.C. Emergency Management Division said a slow, steady rain has begun around the state.
The National Weather Service in Columbia issued a flood warning for the Congaree River, which affects Calhoun, Lexington and Richland Counties.
“Heavy rainfall overnight with amounts from 2 to 4 inches combined with releases from area reservoirs has produced rises along the Congaree River at Carolina Eastman,” in Calhoun County, the advisory said.
Additional heavy rainfall will cause the river to rise over the next several days.
In Charleston, roads are mostly closed because the peninsula has limited access due to tidal flooding.
Midlands city officials remain braced for the forecast deluge over the weekend and into next week.
There were no major problems in Lexington overnight said public safety director David Kerr. The night was “actually pretty calm.”
Two trees that fell blocked side roads, but they are being removed, he said.
By 6:30 a.m. there had been no significant flooding on roads or an increase in calls for help to 9-1-1.
Richland and Lexington counties had gotten 1 to 2 inches of rain by 5:30 a.m., said meteorologist Mike Proud with the National Weather Service.
But the areas were getting rain rates between half an inch to three quarters of an inch an hour early Saturday morning.
“We’re going to start to see more and more flooding,” Proud said.
By 5:30 a.m. there had not been any reports of flooding from the Columbia area, Proud said.
Another concern is wind gusts, Proud said. The rain last week combined with the current system may blow weakened trees into roadways and on power lines, he said.
