Bangladesh is lashed by typhoons, and the Rohingya camps are clustered in a part of the country that records the highest rainfall.
Several days of constant rains have caused rivers to burst their banks in western Chin State, with the townships of Falam and Kalay particularly affected.
Flooding has driven thousands of people from their homes in Mandalay Division as seasonal monsoon rains wreak havoc on the region.
Water levels have risen steadily since unrelenting monsoon rain began in early July, driving some people to higher land or seek shelter in Buddhist monasteries, says official.
“Floodwaters have swept away 23 houses and affected more than 10,000 people,” said Dr. Zaw Win, the regional minister of social affairs for Sagaing Division.
“A day before, the flooding has been about a metre to two metres in the streets,” said a local resident.
