The North Carolina Forestry estimates more than 350 acres of woods and marsh have burned. Smoke billowed for hours forcing some nearby residents from the Summerise development to leave their homes.
Dean Lucas with N.C. Forestry says, "We're gonna try to secure some of the stuff that we haven't been able to during the day due to the weather and possibly set up a game plan to finish it off the first thing in the morning."
Authorities says the investigation into how the fire started is continuing but they believe foul play may be involved.

Another fire in Jones County, out of Pollocksville, scorched 6 acres on Trent Acres Road.
Fire departments from several counties responded and kept the quick moving flames from damaging several nearby homes.
