As the Taninthayi River has risen about 4 feet above its danger level, trade on the Myeik-Mawdaung road has been temporarily cut off. 

The flooding has caused a halt in trade between the Hsinkhun border in Thailand and the Mawdaung border in Taninthayi Township, Myeik District, Taninthayi region.

"According to the observation made by the Department of Meteorology and Hydrology yesterday morning, the water level of Taninthayi River already reached over 27 feet and 7 inches. Many parts of the roads are submerged, and big vehicles cannot pass. Many vehicles are trapped in the Letaungyar village," said one of the drivers.

As of the morning of July 27, the Taninthayi River in Taninthayi Region was only six inches away from the danger level of 24 feet. By the afternoon, it had reached this critical point, causing flooding in over 10 villages, including areas in and around Taninthayi Town.

"Myeik-Mawdaung is one of the main trading areas. Since the night of July 28, trucks haven’t been able to pass on the Myeik-Mawdaung road. With heavy rains, the water level of Taninthayi River has increased, raising concerns about potential commodity losses," said a local resident.

While the Myeik-Yangon Union Highway remains in use, no vehicles can pass through on the Myeik-Taninthayi-Mawdaung road and the Myeik-Taninthayi-Kawthaung union highway. 

The Myeik-Mawdaung trading route, located in the Myanmar-Thai border trade zone, is vital for Myeik District, which primarily exports marine products to Thailand. Merchants are concerned about the potential costs and losses they may face due to the disruption.

The Taninthayi River's warning level is 17 feet, and the danger level is 24 feet. With ongoing rainfall, the river poses an increasing threat.
