The flood release 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 could also cause canals and tributaries to overflow.

Nation TV reported on September 26th that flooding caused by the overflowing Ping River in Mueang County, Chiang Mai Province, was even worse than in 2011.

Heavy rains on the Ping River caused flooding in residential and commercial areas of Mueang County on the night of September 25, including the San Pa Khoi market, Charoen Prathet neighborhoods, and the Night Bazaar. At least 2,000 households are expected to be affected by the flooding, particularly those in and around the Night Bazaar, where water levels exceeded 1 meter.
