Dry conditions, wind and trees downed by Hurricane Helene fueled wildfires in North Carolina and South Carolina, where evacuation orders were in effect Tuesday.About 80 miles (129 kilometers) west of Charlotte, North Carolina, officials ordered mandatory evacuations for roughly 165 properties in rural Polk County. Three fires there have burned at least 9 square miles (23 square kilometers). The North Carolina Forest Service says two of the fires are uncontained as of Monday night.The Black Cove Fire is one of the larger blazes. Officials said a downed power line sparked that fire, but the causes of the other two fires are under investigation.Neighboring Henderson County issued voluntary evacuation orders and opened an emergency shelter. Volunteer fire departments were on standby, Henderson County spokesperson Mike Morgan told WLOS-TV.“Especially near some of the homes where if the fire did jump, we can be there to help protect those homes,” Morgan said. “We’re here to monitor the situation very closely.”Two fires were burning in the mountains of South Carolina. The fires in Table Rock State Park and nearby Persimmon Ridge have burned a combined 2.3 square miles (5.9 square kilometers), the South Carolina Forestry Commission said. Officials said both fires were ignited by human activity and neither were contained as of Monday night.No injuries were reported, and no structures were imminently threatened as of Monday night, but voluntary evacuations were issued for about 100 homes over the weekend. On Tuesday morning, officials called for voluntary evacuations along a road northeast of the Persimmon Ridge Fire, encouraging residents and businesses to evacuate because of winds that could push the flames eastward, the forestry commission said in a social media post. It wasn't immediately clear how many homes and businesses were affected.“The weather over the next few days remains concerning, as relative humidities are expected to remain very low, and the forecasted wind speeds will still be conducive to spreading the fire,” the forestry commission said.Subscribe to WXII's free YouTube channel hereDry weather and millions of trees knocked down by Hurricane Helene last year are creating a long and active fire season in the Carolinas, according to North Carolina State University forestry and environmental resources professor Robert Scheller.
