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.
Maitree Pitinanont, irrigation director in Ayutthaya province, said he advised local residents living by the Chao Phraya River to move their belongings to higher ground because it would overflow from next Monday.
He said water from the North reached Nakhon Sawan province at a flow rate of 1,500 cubic metres per second, so the Chao Phraya dam must discharge water at 1,400-1,600 cubic metres per second. Consequently the level of the river below the dam will rise by 1-2 metres, especially in Bang Ban district, which was the lowest area, Mr Maitree said.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.
The Department of Disaster Prevention and Mitigation reported that since Aug 26 floods caused by heavy rains had hit 24 provinces -- Mae Hong Son, Lampang, Kamphaeng Phet, Kalasin, Buri Ram, Samut Prakan, Nakhon Si Thammarat, Phetchabun, Loei, Nan, Sukhothai, Chiang Mai, Chiang Rai, Udon Thani, Ang Thong, Uttaradit, Nong Khai, Phichit, Nakhon Sawan, Nakhon Ratchasima, Phitsanulok, Phayao, Tak and Mahasarakham. Nearly 10,000 families were affected.
Flooding remains in the five provinces of Phichit, Nakhon Sawan, Phayao, Nakhon Ratchasima and Tak.
