Gloomy weather during the past few days was caused by a high pressure covering the area. Although air quality is in the moderate level, forest fires, if occuring, could aggravate haze and smog in the province, the deputy governor said with concern.
Outdoor burning can also worsen the problem. Since January, more than 100 burning locations were found in the province, particularly in Chom Thong, Hot, and Mae Chaem districts, he added.
These areas are closely monitored to prevent forest fires, mostly caused by burning by locals who are seeking forest products, Mr Adisorn said. Since the beginning of this year, some 800 rai forest (about 320 acres) have been damaged by burning.
