From Chiang Mai Mail> Forest fires have cancelled four air flights from Chiang Mai to Mae Hong Son in the past two days. Wild fires broke out around Mae Hong Son provincial town, resulting in very thick smoke with poor visibility forcing Nok Air to cancel flights on March 8. The volume of minute particles continues to rise since the 8th and is nearly at the maximum allowed level, Peerat Ruangsuksai, chief of the Meteorological Station in Mae Hong Son said on March 9, 2011. Nok Air has cancelled its four flights from Chiang Mai to Mae Hong Son on March 8, as well as two more flights on March 9 forcing visitors to cancel their plans. Locals complain of burning and itching eyes and officials have measured the air quality with a PM10 level of 110.1 and the Air Quality Index level at 94.0, near the maximum safe level. Above 120 PM10 and 100 AQI officials warn of health hazards. Wild fires broke out east of Wat Phrathart Doi Kongmu and in the mountainous areas of villages in Tambon Pang Moo and Tambon Huay Pooling, the remoteness of the locations has caused firefighters great difficulty in trying access the fires. “There are forest fires around Mae Hong Son city, but also in Pai and Pang Mapha (Sapong) districts, as well as along sides of Highway 1095 –Mae Hong Son –Pang Mapha-Pai,” he added.
