MCCLELLANVILLE -- Two state Forestry fire investigators will be in McClellanville Thursday morning, looking into the cause of the fire that has now burned 1,100 at the Georgetown/Charleston County line.
The fire is now being officially called "The Windy Fire."
Agencies began responding to the fire at about 2:47 p.m. It was reported originally as a 200 acre wildfire with 20-30 foot flames.
The fire is contained, but crews are still monitoring the fire and putting out hot spots.
Smoke from this fire has been reported throughout Horry and Georgetown counties.
Highway 17 North through Charleston County was closed Wednesday evening and overnight, but it was opened to traffic Thursday morning.
The South Carolina Forestry Commission says three structures burned in the fire, but there may be more.
They also report power lines are down in the area.
South Carolina Forestry Commission spokesman Scott Hawkins says although some rain fell in the area of the fire over night, it wasn't enough to dampen the risk of wildfires that still exists today. People are encouraged not to burn outdoors.
Hawkins says an illegal trash burn is to blame for a brush fire that burned 50 acres in Little River Wednesday.
