Heavy rain in Nan province in northern Thailand caused local rivers to overflow earlier this week, flooding several districts in the province. Further flood warnings have been issued for 20 provinces, especially in northern and north eastern areas.
One person is said to be missing in Thung Chang district after being swept away by the flood water. Flooding has particularly affected the districts of Thung Chang, Muang and Song, where around 50 houses and areas of farmland have been damaged.
Although the flood water was said to be receding by late Wednesday 20 August in Nan, flooding has since affected the northern provinces of Phrae, Lampang and Phayao.
Flood Warnings for Northern Thailand
Thailand authorities have warned that heavy monsoon rains will increase the likelihood of flooding and landslides over the next few days, particularly in the north and north east.
According to the Thai News Agency, at least 20 provinces are likely to be affected, including Tak, Sukhothai, Pitsanulok, Uttaradit, Phetchabun, Chiang Mai, Mae Hong Son, Lampang, Lamphun, Chiang Rai, Phayao, Phrae, Nan, Nakhon Phanom, Sakhon Nakhon, Nong Khai, Bueng Kan, Udon Thani, Loei, and Nong Bua Lam Phu.
The heavy rain is also likely to affect parts of Myanmar, Vietnam and Laos where flooding has already been reported in areas bordering Thailand. In a 24 hour period, 122 mm of rain fell in Savannakhet Province between 20 and 21 August 2014, according to WMO.
