BMA urges 11 riverside communities to move valuables ahead of high tide

The Bangkok Metropolitan Administration (BMA) has urged residents in 11 communities outside flood embankments along the Chao Phraya River to move belongings to higher ground ahead of possible high-tide flooding on October 28, 2026.

The Royal Thai Navy’s Hydrographic Department forecasts that the tide will peak at 8.29am, with the river level at Pak Khlong Talat potentially reaching 2.02 metres above mean sea level.

City authorities warned that rising water could overflow into riverside homes and community access routes, particularly in areas without permanent flood barriers and locations with a history of flooding.

Eleven communities in six districts on alert

The warning covers riverside areas in Dusit, Phra Nakhon, Bang Kho Laem, Yan Nawa, Bangkok Noi and Khlong San districts.

Residents in the following 11 communities outside flood embankments have been urged to monitor water levels closely and move electrical appliances, valuables and other possessions to higher ground:

• Ratchapha Thapthim Ruam Chai — Dusit.
• Thewarat Kunchon — Dusit.
• Tha Wang — Phra Nakhon.
• Wat Bang Khlo Nok — Bang Kho Laem.
• Wat In Banchong — Bang Kho Laem.
• The community behind Charoen Krung Pracharak Hospital — Bang Kho Laem.
• Matanuson — Bang Kho Laem.
• Rong Si — Yan Nawa.
• Wat Dusit Nimit Mai — Bangkok Noi.
• The community at the end of Soi Charoen Nakhon 29/2 — Khlong San.
• Chang Nak–Saphan Yao — Khlong San.

Residents behind embankments urged to watch for seepage

The BMA also advised residents behind flood embankments along the Chao Phraya River, including royal-initiative and city flood defences, to remain alert for leaks.

The warning extends to communities along Bangkok Noi and Maha Sawat canals.

Higher water pressure could cause seepage through joints in flood barriers, beneath homes or through drainage outlets. Residents who notice leaks should promptly notify officials and, where safe, use sandbags as a temporary protective measure.

Five precautions for households in flood-risk areas

Residents have been advised to take the following precautions:

1. Follow official updates. Monitor warnings from the BMA and the Royal Thai Navy’s Hydrographic Department, particularly around the forecast high-tide period.
2. Move belongings to higher ground. Raise electrical appliances, extension leads, important documents and valuables above any floodwater expected to enter the property.
3. Prepare to disconnect electricity safely. Locate circuit breakers and check electrical sockets in advance. If water begins entering the home, switch off power to affected floors only if the breaker can be reached safely from a dry location.
4. Prepare emergency supplies. Keep drinking water, regular medicines, torches, power banks and other essential items ready for use.
5. Plan assistance for vulnerable residents and pets. Pay particular attention to children, older people and bedridden patients, and prepare to move them and pets to a safe area if water rises rapidly.

City checks flood barriers and prepares standby pumps

The BMA said it had assigned officials to inspect the condition of embankments, accelerate drainage through major canals and prepare standby pumps at vulnerable locations.

High tides can combine with water flowing downstream from northern Thailand and accumulated rainfall to raise river levels further. Residents have therefore been urged to continue monitoring conditions and follow official instructions.
