Due to the rising water levels of the Thanlwin River, widespread flooding has occurred in Hpa-an Township, Kayin State, resulting in the displacement of thousands of residents, according to local social rescue organizations.

As of 6:00 a.m. on July 25, the river level had surpassed the danger mark of 750 centimeters in Hpa-an, reaching 778 centimeters. By 6:00 a.m. on July 26, the level had further increased to 850 centimeters, leading to flooding in the town's low-lying areas.

The flooding has primarily affected Wards 1, 2, and parts of Ward 5, as well as other riverside communities. Social relief organizations in Kayin State, including the Myanmar Rescue Organization (Kayin), have assisted with the relocation of flood victims to designated shelters such as Basic Education High Schools (BEHS) 1 and 3, and the covered sports stadium.

An official from the rescue group stated, "As of the night of July 26, more than 4,000 people had been displaced. With river levels still rising today (July 27), that number is expected to increase."

Flooding has also been reported along other stretches of the Thanlwin River, with communities along its banks experiencing similar inundation.

Additional areas in Kayin State affected by the flooding include Hlaingbwe, Shwegun, Kamamaung, Hpa-an, and the Myinekalay region on the western bank of the Thanlwin River, as confirmed by local residents and rescue teams.

Efforts to relocate affected individuals are ongoing, with joint assistance provided by the Myanmar Fire Services Department, local rescue groups, and community members.

As of 1:30 p.m. on July 27, the river level in Hpa-an had risen to 896 centimeters—well above the danger level—prompting authorities to urge all residents in low-lying and riverside areas to evacuate to safer locations.
