The release of floodwaters is expected to raise water levels in the Phong Pheng Canal (Ang Thong Province), Bang Ban Canal and Noi River (Ayutthaya Province) by 1 to 1.5 meters. The rising water levels may also cause canals and tributaries to overflow.

The Thai Department of Irrigation reported that as of 7:00 a.m. on September 26, the water level at station C2 (Muang district, Nakhon Sawan province) had increased by 21 cm compared to the previous day, but was still 3.29 m lower than the bank. The flow rate at this station was 1,846 ^m3 /second.

At station C3, also known as Chao Phraya Dam, the water level rose slightly compared to September 25 but was still 3.52 m lower than the shore. The flow at this station was 1,498 ^m3 /second.

Nation TV reported on September 26 that flooding caused by the Ping River overflowing its banks in Mueang district, Chiang Mai province was even worse than in 2011.

Heavy rains in the Ping River flooded residential and commercial areas in Mueang district on the night of September 25, including San Pa Khoi Market, Charoen Prathet Street and Night Bazaar.
