Thailand Warns 54 Provinces of Flash Floods, Landslides

BANGKOK — 3 September 2026, Thailand’s Department of Disaster Prevention and Mitigation (DDPM) has warned 54 provinces, including Bangkok, to prepare for possible flash floods, forest runoff, landslides and urban flooding from 4 to 7 September. DDPM Director-General Teerapat Katchamat said on 3 September that the Central Disaster Prevention and Mitigation Command had been monitoring weather conditions and assessing potential risks following a warning from the Meteorological Department about heavy to very heavy rain in upper Thailand from 4 to 7 September. The Meteorological Department said some areas, particularly in the North and upper Northeast, could experience heavy to very heavy rainfall as a monsoon trough moves across the North and upper Northeast. A moderate southwest monsoon is also prevailing over the Andaman Sea, Thailand and the Gulf of Thailand. The areas being placed under close watch for flash floods, forest runoff, landslides and flooding are: North — 17 provinces: Mae Hong Son, Chiang Mai, Chiang Rai, Lamphun, Lampang, Phayao, Phrae, Nan, Uttaradit, Tak, Sukhothai, Kamphaeng Phet, Phitsanulok, Phichit, Phetchabun, Nakhon Sawan and Uthai Thani. Northeast — 20 provinces: Loei, Nong Khai, Bueng Kan, Nong Bua Lamphu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Chaiyaphum, Khon Kaen, Maha Sarakham, Kalasin, Mukdahan, Roi Et, Yasothon, Amnat Charoen, Nakhon Ratchasima, Buri Ram, Surin, Si Sa Ket and Ubon Ratchathani. Central and eastern regions — 17 provinces: Kanchanaburi, Ratchaburi, Phra Nakhon Si Ayutthaya, Lop Buri, Saraburi, Nakhon Nayok, Prachin Buri, Sa Kaeo, Chachoengsao, Chanthaburi, Trat, Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram and Samut Prakan, as well as Bangkok. The Central Disaster Prevention and Mitigation Command, through DDPM, has coordinated with the 54 provinces, regional disaster prevention and mitigation centres and authorities in high-risk areas to prepare for increased rainfall and heavy to very heavy rain that could trigger flooding. Authorities have been instructed to closely monitor weather conditions, rainfall and water levels, while deploying response teams and disaster-relief machinery to vulnerable areas so they can respond quickly and assist residents when needed. Particular attention will be paid to areas at risk and locations that receive accumulated rainfall of more than 90 millimetres within 24 hours, with the aim of minimising the impact of flooding. Authorities have also been instructed to prepare temporary shelters with sufficient capacity to accommodate people who may need to evacuate. Natural tourist attractions, particularly caves, waterfalls and cave passages, must be closely monitored. If there is a risk of dangerous conditions, authorities have been told to issue warnings and strictly prevent people from entering affected areas. The DDPM also urged residents to closely follow official weather updates and disaster warnings and to prepare in advance if they live in vulnerable areas. People are advised to continuously monitor weather conditions, disaster alerts, local water situations and government announcements. Disaster warnings are available through the THAI DISASTER ALERT application. People needing assistance can report incidents through the DDPM’s “ปภ.รับแจ้งเหตุ1784” Line account or call the 1784 disaster hotline, which operates 24 hours a day.
