A state of emergency has been declared in South Carolina as wildfires caused by dry and gusty conditions have forced people to evacuate some areas.
More than 175 fires covered 6.6 square miles in the state on Sunday as the National Weather Service warned of an increased risk of blazes in the region.
The number of fires was down to 163 by early Monday, the state’s forestry commission said.
South Carolina governor Henry McMaster declared a state of emergency on Sunday to support the wildfire response effort and a state-wide burning ban is in effect.
People in eight neighbourhoods were forced to evacuate as several fires raged in the state’s Horry County, officials said.
Soldiers used two Blackhawk helicopters to drop water 600 gallons at a time on the blazes, the South Carolina National Guard said on Sunday.
Meanwhile, firefighters made progress containing a fire in Carolina Forest, where people had been ordered to evacuate several neighbourhoods, according to Horry County Fire Rescue.
Footage showed some people running down the street as smoke filled the sky.
However, Horry County Fire Rescue announced by late Sunday that Carolina Forest evacuees could return home.
The Red Cross of South Carolina said approximately 135 Carolina Forest residents had taken shelter in a county recreation centre.
The fire in the area had burned 2.5 square miles as of Sunday evening, the South Carolina Forestry Commission estimated.
No structures had succumbed to the blaze and no injuries had been reported as of Sunday morning, officials said.
It came as fire crews were working to contain multiple wildfires burning in four forests across North Carolina.
The largest covered around 0.6 square miles and burned in Uwharrie National Forest – about 50 miles east of Charlotte.
The North Carolina Forest Service said on Sunday that it had been made progress on the fire, reaching about one-third containment.
The small southwestern town of Tryon in Polk County, North Carolina, had urged some residents to evacuate on Saturday as a fire spread rapidly there.
The evacuations remained in effect on Sunday.
A decision on whether to lift the evacuation orders was expected to be made on Monday after intentional burns are set to try to stop the fire from spreading.
That fire had burned about 0.8 square miles as of Sunday evening, with 0% containment, according to the Polk County Emergency Management and Fire Marshal’s office.

The North Carolina Forest Service was conducting water drops and back-burning operations on the ground and residents should expect a lot of smoke during those operations, officials said.
It comes as at least six active fires were burning in Georgia on Sunday, with nearly 5.8 miles burned in a seven-day span that brought the region gusty winds and low humidity, according to a Georgia Forestry Commission fire summary.
Officials have not said what caused any of the fires.
The dry and gusty conditions fuelling the fires are expected to fade as a cold front pushes out the dry air mass over the southeast of the US and brings rain by Tuesday, the National Weather Service said.
The convergence of warmth, dry air and gusty winds is not inconsistent with the season’s La Niña weather phenomenon, which is associated with warmer, drier winters in the Carolinas, according to North Carolina State University.
