The floods began in late August, and at their peak in early October had inundated 47 of Thailand's 76 provinces, as well as broad swathes of central and eastern Myanmar.
In Thailand, 207 people have been killed, the interior ministry said in a statement. Nineteen others have been killed in Myanmar.
The Thai ministry said 15 central provinces were still battling high waters.
Thailand's public health ministry also said in a survey that 90 percent of flood victims had drowned, and some 27 percent of those drowning victims were drunk at the time.
Thais are among the world's heaviest drinkers. A health ministry study two years ago found Thailand ranked only behind Portugal, Ireland, the Bahamas and the Czech Republic in terms of alcohol consumption.
