Flooding struck 16 provinces on Sunday, mostly in the Central Plain hit by deluges of water from the Chao Phraya River, and the highest number of affected households was in Ayutthaya province.
However, the present flow in the Chao Phraya River was not affecting Bangkok, according to its governor.
The Department of Disaster Prevention and Mitigation reported that flood levels were either stable or lower in six northern provinces – Nakhon Sawan, Phetchabun, Phichit, Phitsanulok, Sukhothai and Uttaradit.
Meanwhile, the Chao Phraya River basin in the Central Plain was receiving deluges of water from the upper section of the Chao Phraya River. The river basin is low-lying and the local section of the Chao Phraya River is a bottleneck, the DDPM said.
Floods struck parts of eight provinces in the Central Plain, namely Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Suphan Buri, Ayutthaya, Pathum Thani and Nakhon Pathom.
Floodwater receded in Uthai Thani and Sing Buri and remained unchanged in Chai Nat and Suphan Buri.
Flood levels were rising in Ang Thong, Ayutthaya, Pathum Thani and Nakhon Pathom. The highest number of affected households nationwide was 43,458 in 11 districts of Ayutthaya.
The DDPM warned people in Muang and Sam Khok districts of Pathum Thani that the levels of the Chao Phraya River were increasing there.
In the Northeast, only Ban Khawao district of Chaiyaphum province suffered flooding and its level was rising.
In the East, people in Bang Nam Prieo district of Chachoengsao province saw declining flood levels.
The DDPM said 102,051 households were affected in the 16 flooded provinces and the dealth tolls in the provinces reached 12 as of Sunday.
