Government Warns Three Provinces to Monitor Flooding

The Flood Information Center reiterates that rainfall in Bangkok is decreasing and warns Kanchanaburi, Phetchaburi, and Rayong to remain vigilant. Officials confirm that Khao Chuk Dam in Rayong has not ruptured—only the spillway is damaged. The public is advised to heed official warnings and avoid returning to flood-risk areas. The government is preparing to present a relief and rehabilitation framework to the cabinet.

At 10:45 a.m. on September 28, Government Spokesperson Ekapop Piaprasert announced that widespread flooding across Bangkok, its outskirts, the Eastern Region, and the Western Region was caused by drainage unable to keep pace with heavy rainfall. Currently, rainfall in Bangkok is light and moving west; rain is expected to decrease significantly by September 29. Water drainage in Bangkok continues, and many areas have returned to normal, though some communities remain flooded, including Keha Rom Klao, Khlong Chan, Ladprao, and Rama Kamhaeng 24. Drainage into Bang Pa Pong River faces difficulties and continues at full capacity. Thonburi-side water levels are lower than in previous days, reducing drainage risks into the Chao Phraya River. Residents needing assistance can contact Bangkok's hotline 1555 or the Department of Water Resources hotline 1784.

Rain systems in Bangkok are moving westward to Kanchanaburi, where both Vachiralongkorn and Srinakarin dams retain significant water-holding capacity. Authorities have reduced their spillage to protect downstream residents. Water flowing into Khlong Kwai toward Ratchaburi must also be monitored. The public in Nong Prue and Bo Ploy subdistricts, Kanchanaburi, should follow official announcements closely and prepare to evacuate. In Phetchaburi, four districts—Kaeng Krachan, Tha Yang, Ban Lat, and Mueang Phetchaburi—require increased spillage from Kaeng Krachan Dam due to local rainfall; low-lying and riverside residents should prepare and monitor updates.

In the Eastern Region, Rayong still experiences rain while Prasae Reservoir holds over 330 cubic meters—112 percent of capacity—requiring spillway discharge and necessitating vigilance downstream in Kaeng subdistrict. Khao Chuk Dam, subject to rumors of imminent failure, has been inspected and found intact; however, the right spillway wing has been damaged by water erosion. The Department of Water Resources is conducting repairs. The public should monitor official updates closely.

In the Eastern Region provinces of Prachuap Khiri Khan, Sa Kaeo, and Rayong, scattered rain continues despite falling water levels. Residents are urged to consult local authorities and municipal organizations before returning home. Those in Thung Khwam Kin, Kaeng, Wang Chanthorn, and Khao Chachachao subdistricts should remain in safe areas first; call the Department of Water Resources hotline 1784 for updates.

Recovery and rehabilitation will be handled in two phases: affected areas will compile data for budget proposals, while Bangkok's relief will follow the governor's framework with government supplementary support where needed. On September 29, a financial framework will be presented to the cabinet for consideration, pending final figures from Bangkok.
