Severe monsoon rains cause flooding and displacement on Myanmar-Thailand border

What happened

The Democratic Voice of Burma (DVB) reports that heavy monsoon rains have caused the Thaungyin (Moei) River to overflow, resulting in severe flooding in the border towns of Myawaddy in Myanmar’s Karen State and Mae Sot in Thailand. Thousands of residents and commercial vendors in low-lying communities have been forced to evacuate as water levels continue to rise on both sides of the river.

The Thaungyin River, which separates Myawaddy Township from Mae Sot district in Tak Province, overflowed by more than one meter, inundating municipal wards, border markets, and residential areas. In Mae Sot, flash flooding submerged major markets under 30 to 50 centimeters of water, prompting rescue teams to deploy long-tail boats and emergency vehicles to evacuate vulnerable populations including the elderly, patients, and livestock.

In Myanmar, low-lying riverside wards in Myawaddy, located about 130 kilometers east of the Karen State capital Hpa-An, were flooded with thousands of families moving belongings to higher ground and seeking shelter in local monasteries. Flooding disrupted border transport beneath the First Thai-Myanmar Friendship Bridge, forcing more than 200 vendors to evacuate their inventory, highlighting the economic impact on border trade and local livelihoods.
