On Tuesday, the Royal Irrigation Department warned 11 provinces – Bangkok, Samut Prakan, Pathum Thani, Nonthaburi, Chainat, Singburi, Angthong, Suphanburi, Phra Nakhon Si Ayutthaya, Lopburi and Uthai Thani – to be ready for more water released from the Chao Phraya Dam in Chai Nut province. 
Aswin explained that Bangkok’s flood barriers along the Chao Phraya River can resist water levels of 2,500 to 3,000 cubic metres per second. City officials have been ordered to check and repair barriers along the city’s main river and canals. 
Officials have also placed sandbags in flood-prone communities to protect residents. The governor said that city workers were on standby to build temporary bridges in case flooding overwhelmed some areas.
