The flood surge caused by heavy rains in the North reached the Central Plain provinces of Sukhothai and Nakhon Sawan on Thursday.
Continuous rains in the Yom and the Ngao river basins in the North are swelling the level of the Yom River, that flows to the Central Plain.
The river overflowed its banks and flooded Wat Koh sub-district in Si Samrong district, swamping about 50 houses, the Si Samrong market and Pracha Uthit School. Floodwaters were 30-60 centimetres deep and the school was closed.
The river also overflowed in Pak Khwae sub-district of Muang Sukhothai district, inundating houses and farmland, and was 1.50 metres deep in some areas.
People in Sawankhalok and Kong Krailat districts of Sukhothai, Bang Rakam district of Phitsanulok province and Sam Ngam district of Phichit province were warned of possible flooding as the districts are downstream on the Yom River. Local residents were making sandbags in a bid to cope with incoming deluge.
Persistent rains also generated runoff that hit about 1.6 square kilometres of paddy fields in Sam Ngam district of Phichit, about 100 houses in Si Satchanalai district of Sukhothai, and about 1.6 square kilometres of paddy fields and four villages in Phaisali district of Nakhon Sawan.
