The death toll from floods in Myanmar is expected to rise over the coming days, the United Nations has warned.
Four western regions have been declared disaster zones after heavy floods, caused by monsoon rains, left at least 27 people dead.
But rescue teams have not yet reached many areas and are still awaiting reports on the worst-hit regions.
In the neighbouring eastern Indian state of Manipur, a landslide buried a village, killing at least 21 people.
Heavy rains are normal in monsoon season, but many people in Myanmar - also known as Burma - told the BBC that the rains were particularly strong in recent weeks.
Wind and rain from Cyclone Komen added to damage.
On Sunday, the UN Office for the Coordination of Humanitarian Affairs said some 156,000 people were affected by the floods in 12 districts but the total could be "significantly higher".
The UN also said:
Heavy rains are expected in many states, including Chin, Rakhine and Magwe, over the next two days, forecasters say.
Thousands of people are sheltering in Buddhist monasteries, but one report said people from the Rohingya Muslim minority were turned away from some shelters.
The Burma Times said security forces turned away Rohingya Muslims from abandoned schools and community centres in Rakhine.
More than half a million acres of rice paddy fields have been flooded, the Ministry of Agriculture and Irrigation said.
The landslide in Manipur state hit a remote village in Chandel district, bordering Myanmar, early on Saturday.
Rescue teams are expected to reach the area only on Sunday because of heavy rains and landslides, a local MP said.
Continuous rain in recent days has washed away bridges and roads and left thousands homeless, India's NDTV reported.
Elsewhere, floods in Vietnam left at least 17 people dead and in western Nepal, some 36 people were killed after torrential rain triggered landslides.
