Seven Provinces Face Landslide, Flashflood Risk from Heavy Rain
Seven northern and northeastern provinces face landslide and flashflood risks from heavy rain expected through August 18, with authorities urging volunteer networks to monitor conditions closely.
The Department of Mineral Resources has named seven provinces at risk of landslides and flashfloods from heavy rain, urging volunteer networks in vulnerable areas to monitor the situation closely. On August 18, 2025, the Geohazard Operations Center of the Department of Mineral Resources, Ministry of Natural Resources and Environment, warned of landslides and flashfloods due to continuous heavy rain in at-risk areas and predicted rainfall that could trigger landslides, particularly in seven provinces: Tak, Nan, Chiang Mai, Phitsanulok, Phetchabun, Loei, and Sa Kaeo. The Meteorological Department forecasts heavy to very heavy rain in parts of Thailand over the next 24 hours, with the most intense rainfall in the upper Northeast and Eastern regions as the monsoon trough shifts southward through Laos into a low-pressure system over northern Vietnam, while the strengthening southwest monsoon affects the Andaman Sea, Thailand, and the Gulf of Thailand. The public should beware of dangers from heavy and accumulated rainfall, which may trigger flash floods, flashfloods, and overflowing banks, particularly in hillside areas near water channels and low-lying zones. Volunteer networks in these at-risk areas are instructed to closely monitor landslide and flashflood conditions and prepare for potential geohazards. If geohazards occur in any area, officials must immediately inspect the site to reassure residents and provide preliminary guidance.
