The combination of dry fuels, near critical low relative humidity, and gusty winds will lead to increased fire danger conditions during Saturday across southeast North Carolina. Relative humidity values are expected to drop to 25 to 35 percent during the afternoon, with the lowest humidities across inland areas. In addition, southwesterly winds of 10 to 15 mph with gusts to 15 to 20 mph are expected, with the highest winds along the coastal areas.

The combination of dry fuels, gusty southwest to west winds, and low relative humidity of about 20-30% in the afternoon into the evening will lead to an increased risk for the rapid spread of wildfires. Most dry grasses, dead leaves, and other tree litter could easily ignite and spread fire quickly. A statewide burn ban issued by the North Carolina Forest Service is currently in place. Open burning of any kind is illegal.
