DDPM warns of high tides and potential flooding in 6 provinces and Bangkok from January 18-22

The Department of Disaster Prevention and Mitigation (DDPM) on Friday issued a warning for 7 provinces in central Thailand to prepare for high tides between January 18-22, 2026. The affected provinces are Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram, Samut Prakan, and Bangkok. Local authorities are advised to alert businesses and residents living along rivers and canals, especially in low-lying areas outside the flood barriers, to monitor water levels and prepare for potential flooding.

DDPM Director-General Teerapat Khajamat explained that during the period between 07:00 - 10:00 on January 18-22, the high tide will cause water levels in the Chao Phraya River, particularly near the Naval Command Headquarters and Phra Chulachomklao Fort, to rise. This could lead to overflowing rivers and an increase in water levels, potentially flooding low-lying areas along the riverbanks, including communities outside flood barriers or temporary embankments.

The provinces at risk include:

• Pathum Thani (Muang Pathum Thani and Sam Khok districts)
• Nonthaburi (Muang Nonthaburi, Pak Kret, and Bang Kruai districts)
• Nakhon Pathom (Bang Len, Nakhon Chai Si, and Sam Phran districts)
• Samut Sakhon (all districts)
• Samut Songkhram (Muang Samut Songkhram district)
• Samut Prakan (Muang Samut Prakan, Phra Samut Chedi, Phra Pradaeng, and Bang Bo districts)
• Bangkok

DDPM urges local governments to inform the public about the high tide periods and warn private sector businesses operating along rivers, such as riverbank construction projects and food vendors. Residents in low-lying areas along the river are also advised to remain vigilant and monitor the situation closely. Authorities are preparing public disaster response teams and equipment to be on standby and ready to assist affected communities.

For updates, residents can track alerts through the 'THAI DISASTER ALERT' app. Those in need of assistance during an emergency can contact DDPM via Line ID: @1784DDPM or call the emergency hotline 1784 (available 24/7) for immediate support.
