Unusually heavy monsoon rains during July and August 2015 caused severe floods in large parts of Myanmar. The country annually receives abundant rain during these months, but during the 2015 monsoon season the precipitation amount was much higher due to cyclone Komen. The floods affected several million people and destroyed more than 5,000 km^2 of farm land (source: United Nations Office for the Coordination of Humanitarian Affairs [OCHA]).
