Heavy rain is continuing in flooded parts of Thailand where the government is trying to protect Bangkok.
At least 252 people have been killed since mid-July when there was a tropical storm followed by monsoon rains since then.
Prime Minister Yingluck Shinawatra is warning residents in Bangkok to prepare to be directly affected.
Parts of Bangkok near the swollen Chao Praya River are already flooded and Ms Shinawatra has warned there is more to come.
The ABC reports areas upstream of Bangkok are flooded to depths of more than two metres in places.
Ms Shinawatra has ordered the digging of seven new canals to help the water escape.
The flooding in parts of Thailand is the worst in 50 years,
