A peat swamp fire in Phru Khuan Khreng, Nakhon Si Thammarat, has burned about 300 rai in Cha-uat district and is affecting seven villages on the edge. Officials expect it to be under control within a few days unless strong wind returns, and a helicopter is surveying its extent. For Thai SMEs in the south, the practical impact is possible smoke and air quality issues, and some disruption to local travel or deliveries near Cha-uat. No action is needed beyond staying alert to official updates.
